BS EN 13953 is a document on LPG equipment and accessories. BS EN 13953 specifies the design, testing and marking requirements for spring-loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and including 150 l.
BS EN 13953 calls for the use of substances and procedures that may be injurious to health and/or the environment if adequate precautions are not taken. BS EN 13953 refers only to technical suitability.
BS EN 13953 on LPG equipment and accessories is useful for:
BS EN 13953 implementation on LPG equipment and accessories introduces a pressure relief valve for transportable refillable cylinders for Liquefied Petroleum Gas (LPG) which automatically, without the assistance of any energy other than that of the vapour concerned, discharges vapour at a predetermined pressure.
The more specified function of LPG equipment mentioned in BS EN 13953 is that these valves are designed to open at a pre-set pressure and discharge fluid until the pressure drops to acceptable levels.
Implementation of BS EN 13953 on LPG equipment and accessories is beneficial for you as this design protects life and property by venting fluid from an over-pressurized vessel.
