BS EN 13274 discusses respiratory protective devices. BS EN 132747 is an international standard on the determination of particle filter penetration in respiratory protective devices to protect the wearer from inhaling hazardous air. BS EN 132747 is the seventh part of a multi part series that specifies the procedure for testing particle filter
