NFPA 1992 Standard on Liquid Splash-Protection Ensembles and Clothing for Hazardous Materials Emergencies, 2005 Edition.
When Liquid Splash Protection Is Needed
NFPA 1992 is the standard that tests a garment’s protection against liquid chemical splashes. It does not test for protection against vapour penetration, this is carried out under NFPA 1991.
Garments are tested under NFPA 1992 for penetration resistance against specific chemicals using test method ASTM F903. Penetration is defined as the bulk flow of a liquid through the material, seams or closures of a suit.
In addition to the fabric, the overall ensemble must also demonstrate liquid-tight integrity. NFPA 1992 provides test methods and criteria for making this assessment.
When Liquid Splash Protection Is Needed
Test method
The penetration test (ASTM F903, Procedure C) measures the resistance of protective clothing materials to penetration by liquids using a one hour, one-sided liquid exposure to the normal outside material surface. The test is initially conducted at atmospheric pressure. During the sixth minute, the test is conducted at 2 psi to simulate the pressure from a burst pipe. Liquid penetration is detected visually at the end of the test. Penetration results are recorded as either “PASS” or “FAIL”.
