Terms of Service

Editorial content

Articles are provided for professional reference and general information. They describe requirements as we understand them from the cited public sources. They are not the standard itself and they are not professional, legal or engineering advice.

You may read, print and quote articles with attribution and a link to the source page. You may not republish them wholesale, resell them, or feed them into a competing content site.

Reference packs and licence

A reference pack is a digital compilation of our published articles, assembled into a single PDF. Buying one grants you a non-exclusive, non-transferable licence for personal and internal professional use.

You may store the PDF on your own devices, print it for your own use, and share it with colleagues inside your organisation. You may not redistribute it publicly, resell it, upload it to a file-sharing or AI-training corpus, or use it to build a competing product.

Payment, delivery and refunds

Payments are handled by PayPal in US dollars. Delivery is by emailed download link, normally within seconds of payment confirmation; the link is time-limited and bound to a download allowance per purchase.

Because the product is delivered digitally and in full at the moment of download, statutory withdrawal rights for digital content may not apply once download has begun. That said, we offer a no-questions-asked refund within 30 days: write to us and we will refund the purchase.

Availability and changes

We aim to keep the site available but do not guarantee uninterrupted service. Content is continuously reviewed; articles may be corrected, expanded, retired or reorganised, and reference packs may be updated as the underlying articles change.

These terms may be updated. The version published on this page at the time of your purchase governs that purchase.

Liability

To the extent permitted by law, our total liability arising from your use of the site or a reference pack is limited to the amount you paid for the product in question. Nothing in these terms excludes liability that cannot lawfully be excluded.
