Flame-resistant garments for protection of industrial workers against flash fire.
Standard for Flame-Resistant (FR) Garments for Protection of Industrial Personnel against Flash Fire.
NFPA 2112:2012 - STANDARD ON FLAME-RESISTANT GARMENTS FOR PROTECTION OF INDUSTRIAL PERSONNEL AGAINST FLASH FIRE
This standard specifies the minimum performance requirements and test methods for FR fabrics and components and the design and certification requirements for garments developed to protect workers from a flash fire hazard. It requires FR fabrics to pass a comprehensive number of thermal tests.
Including the following tests:
• ASTM D6413 - Vertical Flammability Test – maximum 2.0 seconds after flame and 4.0 inch char length.
• ASTM F1930 - Thermal Mannequin Test - maximum predicted body burn after 3.0 second thermal exposure.
• ASTM F2700 - Heat Transfer Performance (HTP) test - minimum HTP of 6.0 cal/cm2 spaced and 3.0 cal/cm2 contact.
• Thermal Stability Test - fabric must not melt or drip, separate or ignite after 2.0 minutes in a 260° C (500° F) oven.
• AATCC 135 - Thermal Shrinkage Test - fabric must not shrink more than 10% after 5.0 minutes in a 260° C (500° F) oven.
