The Licensee shall pay the applicable price for the Product. Once a card payment has been processed, an invoice confirming the payment will be emailed to the Licensee. Orders are paid by credit card and are charged in full at the time the order is placed.
Where invoice payment has been approved by Nimonik in writing, an invoice will be issued for payment in accordance with the following terms:
Payment is due in full within thirty (30) days of the invoice date, unless otherwise agreed in writing by Nimonik.
Payments must be made in U.S. Dollars (USD) and include the relevant order number.
Nimonik may accrue interest on overdue amounts at the rate of 1.5% per month, or the maximum rate permitted by applicable law, whichever is lower, calculated from the due date until paid in full. The Licensee shall be responsible for all reasonable costs of collection, including legal fees.
Nimonik may suspend or withhold delivery of, or access to, any Product until all overdue amounts have been paid in full.
The Licensee is responsible for all bank charges, transfer fees, and foreign exchange risks associated with the payment. The Licensee is also responsible for any local taxes, customs duties, or other charges imposed by the destination jurisdiction.
Sales tax is applied to orders with a billing address in any U.S. state where Nimonik is required to collect such tax. Applicable sales or use tax is determined based on the Licensee’s billing or delivery address.
All orders placed through the Nimonik Online Store constitute an offer to purchase and are subject to acceptance by Nimonik. Nimonik may, in its sole discretion, refuse, limit, or cancel any order, or any quantity ordered, at any time prior to fulfilment, for any reason it deems appropriate.
Nimonik uses reasonable efforts to ensure that prices and product information displayed on the Nimonik Online Store are accurate. However, errors may occur. Nimonik reserves the right to correct any errors, inaccuracies, or omissions, and to change or update prices and information at any time without prior notice. In the event a Product is listed at an incorrect price or with incorrect information due to a typographical or other error, Nimonik may, at its discretion, cancel or refuse any order placed for that Product, whether or not the order has been confirmed and payment processed. If payment has already been taken for a cancelled order, Nimonik will issue a full refund of the amount charged.
Products are made available only in one of two formats:
in electronic format, accessible for authenticated users via the Nimonik Online Store, as either a downloadable PDF or a view-only PDF (depending on the digital rights management (DRM) requirements applicable to the Product), or
in hard-copy printed format, dispatched either from Nimonik’s facility in the United States or directly by the publisher or Owner of the Product, depending on the Product.
No other formats are offered.
Products are made available/dispatched once the order has been processed.
Any delivery times, dispatch times, or shipping estimates shown in the Nimonik Online Store or at checkout are approximate and provided for guidance only. Actual delivery times may vary and depend on a range of factors, including order processing, payment clearance, product format, carrier performance, destination, customs handling, and other circumstances beyond Nimonik’s reasonable control. Nimonik does not guarantee any specific delivery or dispatch date and shall not be liable for any delay in delivery.
Returns are not accepted for electronic Products (PDF).
Returns of hard-copy Products may be accepted only in cases of duplicate orders or, on an exceptional basis, on a case-by-case assessment. In all instances, returns are subject to Nimonik’s prior agreement and must follow the procedure specified by Nimonik.
For termination of the use rights, please refer to the End Customer Licence Agreement in Part B.
Nimonik processes personal data provided in connection with an order in accordance with applicable data protection laws, and only as necessary to process the order, deliver the Product, and meet its legal obligations.
For both hard-copy and electronic Products, license rights apply to the content of the Products. Content of Products is made available under licence, as further specified in the End Customer Licence Agreement (Part B), and not sold.
Products are protected by copyright law and other applicable laws. Use of Products, including permitted use, restrictions, intellectual property rights, compliance obligations, and termination, is governed exclusively by the End Customer Licence Agreement.
In the event of any inconsistency, the End Customer Licence Agreement shall prevail with respect to the use of Products.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE PRODUCTS ARE PROVIDED “AS IS” AND “AS AVAILABLE,” AND ARE SOLD AND LICENSED WITHOUT ANY REPRESENTATION OR WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NIMONIK SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH THESE T&Cs OR THE PURCHASE OR USE OF ANY PRODUCT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
NIMONIK’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR IN CONNECTION WITH THESE T&Cs OR ANY PRODUCT SHALL NOT EXCEED THE AMOUNT ACTUALLY PAID BY THE LICENSEE FOR THE PRODUCT GIVING RISE TO THE CLAIM. NOTHING IN THESE T&Cs EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING LIABILITY FOR DAMAGE CAUSED BY GROSS NEGLIGENCE OR INTENT.
IMPORTANT — READ CAREFULLY BEFORE DOWNLOADING, PRINTING, ACCESSING, OR OTHERWISE USING THE PRODUCT.
This agreement (the “Agreement”) sets out the terms on which the Licensee may use the Product. This Agreement is entered into together with, and forms part of the same overall agreement as, the T&Cs.
By placing an order for a Product, or by accessing, downloading, printing, installing, or otherwise using the Product, the Licensee accepts and agrees to be bound by this Agreement and the T&Cs. The Licensee shall ensure that it has read and understood all applicable terms before completing the purchase.
Any questions regarding this Agreement may be addressed to Nimonik via https://standards-nimonik.freshdesk.com/support/tickets/new
This Agreement sets out the terms under which Nimonik grants the Licensee access to, and rights to use, the Product, whether in whole or in part.
The licence granted under this Agreement applies only to the specific edition of the Product purchased or downloaded by the Licensee. It does not include any previous or subsequent edition. Unless expressly agreed otherwise in writing, Nimonik does not provide document updates, maintenance, or support services for the Product.
(a) Subject to full payment of the applicable Licence Fee and the Licensee’s compliance with this Agreement, Nimonik grants the Licensee a non-exclusive, non-transferable, limited, and revocable licence to use the Product for use by a single named user. This Agreement does not convey to you any ownership interest in or to the content of the Product.
(b) Permitted use includes the right to access, read, consult, and internally reference the Product, and to understand, evaluate, and apply its content within the Licensee’s own internal operations, processes, and management systems.
(c) Where the Product is provided electronically as a downloadable PDF, the Licensee, as a single named user, may only access the Product as an authenticated user via the Licensee’s Nimonik Online Store account. Unless the watermark or notice on the PDF itself states otherwise, the Licensee may download and store one (1) copy on a single personal device for use by that single user, and may print one (1) copy of the Product for personal use.
Where the Product is provided as a view-only PDF, the Licensee, as a single named user, may access and view the Product online as an authenticated user through the Licensee’s Nimonik Online Store account, but may not download, store, print, or otherwise reproduce the Product.
In all cases, concurrent use by two or more users, and any access to or storage of the Product on shared systems, networks, intranets, or shared drives, is not permitted.
(d) For identification and rights-management purposes, electronic copies of the Product may be watermarked with the account information provided by the Licensee at the time of purchase, including the Licensee’s email address.
(e) Where the Product is provided in hard-copy form, photocopying or reproduction in any form is not permitted without Nimonik’s prior written authorization.
(f) You shall provide Nimonik or any designee of Nimonik with all information reasonably necessary to verify compliance with this Agreement, and shall use your best efforts to cooperate with Nimonik to assure compliance.
The Product is protected by copyright law, database rights, trademark law, unfair competition law, trade secret law, and other applicable laws. The Licensee acknowledges and agrees to respect the Owner’s intellectual property rights in the Product and shall refrain from any act that may infringe, misappropriate, or otherwise violate such rights.
All right, title, and interest in and to the Product, together with any updates, corrections, derivative works, or ancillary materials, and all intellectual property rights therein, are and shall remain with the Owner. Where a Product is supplied in physical form, ownership of that physical medium may transfer to the purchaser; however, all intellectual property rights in the content of the Product remain with the Owner. Nothing in this Agreement assigns, transfers, or grants the Licensee any intellectual property rights in the Product, except for the limited rights expressly set out herein.
If Nimonik or its licensors are no longer authorized to license a Product, or if a claim of infringement arises or in Nimonik’s opinion is likely to arise, Nimonik may withdraw access to the Product temporarily or permanently, and the Licensee shall promptly suspend or cease all use of such Product. Nimonik may also, in its sole discretion, discontinue or withdraw any Product.
(a) General prohibitions. The Licensee shall not: use the Product outside the scope of the licence granted under this Agreement; grant use or access rights to the Product to, or disclose the Product to, any third party; sell, lend, lease, reproduce, distribute, import, export, or otherwise commercially exploit the Product, in whole or in part; merge, adapt, translate, or modify the Product; remove or alter any proprietary notice or label on or within the Product; or assign or otherwise transfer ownership of the Product to any third party.
(b) Artificial intelligence and machine learning. Except under a separate written licence granted by Nimonik or the Owner, the Licensee shall not access, use, or process the Product for or in relation to any machine learning, artificial intelligence (AI), or analogous computational purpose. This restriction includes, without limitation:
training, fine-tuning, or evaluating language models, machine-learning systems, generative AI models, or similar models or systems;
embedding, prompting, querying, comparing, or otherwise enabling an AI or ML model or system to ingest, reproduce, restate, summarize, translate, reformulate, or generate outputs derived from the Product;
structured extraction, text and data mining, harvesting, or processing of the text, structure, logic, metadata, or other elements of the Product for model training, dataset creation, benchmarking, or automated knowledge extraction; or
any other activity intended to enable an AI or ML system to ingest, analyze, internalize, or generate content based on the Product.
The Licensee may not rely on any statutory text-and-data-mining or similar exception to justify AI- or ML-related use of the Product.
The Licensee shall maintain accurate, complete, and up-to-date records relevant to its use of the Product and its compliance with this Agreement. If Nimonik has reasonable grounds to believe that the Licensee is not complying with this Agreement, Nimonik may, upon written notice, conduct an audit or require that an audit be carried out by an independent third-party auditor, during normal business hours at the Licensee’s premises or through remote access, as appropriate. Any underpayment of Licence Fees identified through an audit shall be invoiced to the Licensee and paid in full; if the audit reveals an underpayment, the Licensee shall also bear the reasonable costs of the audit and reimburse Nimonik within thirty (30) days of written notice.
Where the Product or any login credentials, passwords, or access tokens are provided to the Licensee, the Licensee shall keep them confidential and shall not share them with any third party or unauthorized user. The Licensee’s confidentiality obligations shall survive the expiration or termination of this Agreement, and the return or destruction of copies of the Product shall not relieve the Licensee of its continuing obligation to prevent unauthorized disclosure.
(a) Nimonik warrants for your benefit alone that, unless disclosed in the Product to the contrary, Nimonik and the Owner can license the Product and all copyright and trademarks related thereto or therein.
(b) THE EXPRESS WARRANTIES SET FORTH IN THIS SECTION 7 CONSTITUTE THE ONLY WARRANTIES WITH RESPECT TO THE PRODUCT, AND NIMONIK AND THE OWNER MAKE NO OTHER REPRESENTATION OR WARRANTY OR CONDITION OF ANY KIND, WHETHER EXPRESS OR IMPLIED (EITHER IN FACT OR BY OPERATION OF LAW), WITH RESPECT TO ANY OF THE PRODUCT, INCLUDING, WITHOUT LIMITATION, WITH RESPECT TO THE SUFFICIENCY, ACCURACY, OR UTILIZATION OF, OR ANY INFORMATION OR OPINION CONTAINED OR REFLECTED IN, ANY OF THE PRODUCT. NIMONIK AND THE OWNER EXPRESSLY DISCLAIM ALL WARRANTIES OR CONDITIONS OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
The Owner, Nimonik, any agent, representative, publisher, or distributor of the Product, and any of their respective directors, officers, employees, agents, representatives, or members (the “Nimonik and Owner Indemnified Parties”) shall have no liability for, and you shall defend, indemnify, and hold each of the Nimonik and Owner Indemnified Parties harmless from and against, any claim, loss, demand, liability, obligation, and expense (including reasonable attorneys’ fees) based upon or arising out of any injury or damage, or any product liability claim, including but not limited to any personal or bodily injury or property damage, arising out of, pertaining to, or resulting in any way from the use or possession of any of the Product by you and/or any of your directors, officers, employees, representatives, agents, or contractors, or from any breach of this Agreement.
(a) Whether or not Nimonik or the Owner has been advised of their possibility, neither Nimonik nor the Owner nor any of their representatives, agents, directors, officers, employees, or members shall be liable, whether under contract, tort (including negligence), or otherwise, for any indirect, special, punitive, incidental, or consequential loss, damage, cost, or expense of any kind whatsoever and howsoever caused that may be suffered by you or any third party. You are responsible for the consequences of any use of any of the Product.
(b) If an allegation of infringement of third-party rights is made, or in Nimonik’s or the Owner’s opinion is likely to be made, with respect to any Product, Nimonik may, at its option and expense, (i) obtain for you the right to continue using the Product, (ii) modify or replace the Product so as to avoid the claim, or (iii) refund the Licence Fee. Nimonik shall have no liability if any claim would have been avoided except for your refusal to use a modified or replacement Product or to cease using the Product. This Section 9(b) states the entire liability of Nimonik and the Owner with respect to any infringement or alleged infringement of third-party rights.
(c) TO THE MAXIMUM EXTENT PERMITTED BY LAW, AND NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, THE TOTAL AGGREGATE LIABILITY OF NIMONIK AND THE OWNER ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR ANY PRODUCT SHALL NOT EXCEED THE LICENCE FEE PAID BY THE LICENSEE FOR THE PRODUCT GIVING RISE TO THE CLAIM. NOTHING IN THIS AGREEMENT EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING LIABILITY FOR DAMAGE CAUSED BY GROSS NEGLIGENCE OR INTENT.
This licence is granted only for the edition of the Product confirmed in Nimonik’s order confirmation and does not grant any rights to revisions or new editions of the Product. This Agreement may be terminated immediately by the Owner or Nimonik upon breach of any provision by you. Upon any expiration or termination of this Agreement, you shall immediately discontinue all use of the Product and shall, within ten (10) days, either return any hard-copy Product to Nimonik or certify in writing to Nimonik that all electronic copies of the Product (including any printed copy and any backup copy) have been permanently deleted from your devices and eliminated from your premises. Provisions that by their nature are intended to survive termination shall so survive.
You may not load, export, or re-export any of the Product, or any underlying information or technology, except in full compliance with all United States and other applicable laws and regulations.
