BS EN 14432:2023

This standard BS EN 14432:2023 Tanks for the transport of dangerous goods. Tank equipment for the transport of liquid chemicals and liquefied gases. Product discharge and air inlet valves is classified in these ICS categories:

• 13.300 Protection against dangerous goods
• 23.020.20 Vessels and containers mounted on vehicles
• 23.060.99 Other valves

This document specifies the requirements for valves useable on tanks with a minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail for the following functions: Tanks for transport of liquid products: - secondary closure of bottom discharge lines; - primary closure on top of the tank (liquid, air, other connections); - aeration valve on top of the tank; - and other valves as specified in Annex F of EN 14564:2019 according to the scope of this document. Tanks for gases: - secondary closure of bottom discharge lines; - secondary closure on top of the tank for poisonous gases: liquid phase and gas phase; - and other valves as specified in Annex F of EN 14564:2019. This includes the following types of closures: - valves (e.g. spindle operated valves, plug and ball valves, butterfly valves and gate valves); - dry disconnect couplings. Primary closures of the gas phase at the foot of a tank for liquefied gas are covered by the requirements of foot valves in EN 14433. NOTE The standard is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175 [3]
