Protective Clothing Against Liquid Chemicals.
This standard specifies the minimum requirements for limited use and re-usable limited performance chemical protective clothing. Limited performance chemical protective clothing is intended for use in cases of a potential exposure to a light spray, liquid aerosols or low-pressure, low volume splashes, against which a complete liquid permeation barrier (at a molecular level) is not required.
The standard covers both chemical protective suits (Type 6) and partial body protection (Type PB).
Type 6 suits are tested using a mist or fine spray of water with a die added to aid the assessment of leakage. The test subject wears an absorbent suit underneath the one to be tested, which absorbs any leaks and is stained by the die. Success or failure is determined by measuring the total area of any stains on three suits and comparing this with the requirement. A range of other tests as specified, including resistance to abrasion, test strength, tensile strength, resistance to puncture, resistance to ignition, resistance to penetration by liquid chemicals and seam strength. In the test for liquid chemical repellency and resistance to penetration by liquid chemicals, a bank of four test chemicals is given in the standard although the requirement is that the suit material demonstrates adequate repellency and resistance to penetration against just one chemical from this list.
