EN 589:2025 pdf download

EN 589 details the technical requirements and testing protocols for automotive LPG, also known as low-pressure gas, which is designed for use in vehicles fitted with LPG-powered engines.

LPG is a highly volatile hydrocarbon that is commonly stored at high pressure. Upon depressurization, it can produce substantial amounts of gas, capable of forming explosive mixtures with air within a concentration range of roughly 2% to 10% by volume. The standard encompasses the procedures for sampling, handling, and testing LPG. Potential ignition sources include open flames, unshielded electrical appliances, and static electricity.

When in liquid form, LPG can cause frostbite-like injuries upon contact with the skin. Compliance with national health and safety guidelines is mandatory when dealing with LPG.

Additionally, LPG is heavier than air and tends to settle in low-lying areas, increasing the risk of asphyxiation if inhaled at high levels.

EN 589 describes a testing procedure that involves the operator breathing a blend of air and LPG vapor. It is crucial to follow the safety instructions provided in section A.1, which addresses this specific testing method.
