The DIN 2999 standard, an older German version of the Whitworth pipe thread standard, has been superseded by several newer standards, including BS EN 10226 series and ISO 7-1. To purchase the DIN 2999 standard, options include buying from BSI, where members may receive discounts, or checking if it’s available through a subscription. Libraries may also assist in obtaining it at no cost through national library services. These resources provide accessible avenues for acquiring the standard. Understanding the latest standards is crucial for compliance and accuracy in relevant applications.
