Gas welding equipment — Decomposition blockers for high-pressure acetylene

This document establishes the general specifications, requirements and tests for decomposition blockers located on the high-pressure side in battery vehicles and gas containers as defined in EN?13807 or in acetylene bundles as defined in ISO?10961.

NOTE 1?????? The terms “upstream” and “downstream” refer to the normal direction of gas flow in the decomposition blocker. 1?bar = 0,1?MPa = 10⁵?Pa; 1?Pa = 1?N/m². All pressures are expressed in gauge pressures.

NOTE 2?????? This document can be used as a guideline for decomposition blocker for filling centre application.
