Watch now: NFPA 1970 Spotlight Series, Part 7: Moisture Barrier Changes
Learn from UL Solutions expert Andy Kaiser as he explores the critical updates in NFPA 1970 standards and their impact on moisture barrier materials and seams for structural and proximity firefighting gear. This episode delves into the latest performance and testing requirements designed to enhance garment durability and firefighter safety.
Moisture Barrier Standards: What’s New
NFPA 1970 introduces significant updates to moisture barrier materials and seams:
Liquid Barrier Performance Test Option
A new liquid barrier performance test is now available as an alternative to the viral penetration resistance test required under NFPA 1971. Moisture barriers and seams must meet Level 3 barrier requirements of ANSI/AAMI PB70, with testing protocols that include:
- AATCC 42: Water resistance using impact penetration.
- AATCC 127: Water resistance using hydrostatic pressure.
Alternatively, the viral penetration test remains an option, following the same method as NFPA 1971.
UV Light Degradation Test Updates
Testing now requires moisture barrier materials to be exposed to UV in composite form, providing a more accurate simulation of garment conditions. The barrier layer is tested separately for water resistance after UV exposure on both the outer shell and thermal barrier sides.
Heat and Thermal Shrinkage Resistance Test Updates
Moisture barrier materials and seams are now tested in composite form after undergoing laundry conditioning and heat exposure. This change mirrors real-world conditions and ensures accurate evaluation of material performance.
