2 Classification system 1. Single layer garments (Type 1) 2. Multilayer garments (Type 2) 3. Disposable garments (Type 3) General requirement (design) Materials of construction (design) Design can neither adversely affect protective characteristics nor contribute to severity of burn injury to wearer. May be either flameresistant fabrics or 100% cotton or wool Closure system (design) Closure must be constructed to secure garment to provide protection consistent with standard Hardware finish (design) Must be free of rough spits, burrs, or sharp images Metal components (design) Contact with body not permitted Contact with body not permitted Laundering procedure (preconditioning) AATCC 135-3, IV, Aiii (permanent press machine cycle, wash temperature at 49 o C, tumble drying on permanent press setting) Multistage industrial laundering with break, carry-over, 3 rinse cycles, sour and extraction; drying with dryer temperature set at 82 o C (without load) Multistage industrial laundering with break, carry-over, 3 rinse cycles, sour and extraction; drying with dryer temperature of 68 o C (without load) CAN/CGSB-4.2 No. 48 Procedure III E (medium temperature 50 o C, moderate mechanical action, synthetic detergent and tumble drying) Dry-cleaning procedure (preconditioning) ASTM D 2724, paragraph 6.1 AATCC 158 AATCC 158 CAN/CGSB-4.2 No. 30 Page 2 of 6

3 Flame resistance (fabrics) Testing per ASTM D 6413 before and after 25 cycles of laundering or dry-cleaning; Afterflame 2 sec. Char length 152 mm No melting and dripping Testing per ASTM D 6413 before and after 100 cycles of laundering or drycleaning (applies to fabric and reflective tape); Afterflame 2 sec. Char length 100 mm No melting and dripping Testing per CAN/CGSB-4.2 No using edge ignition (fabric for Type 1 and 3, each layer for Type 2) before and after 50 cycles of laundering or 5 cycles of dry-cleaning; Afterflame 2 sec. Char length 100 mm No melting or dripping Flame resistance (primary Same as fabrics closures) Heat resistance (fabrics) Samples exposed to 260 o C for 5 minutes in forced air convective oven; no melting, dripping, or separation permitted; applies to textiles and components, excluding interlinings, collar stays, elastic, and hook and pile fasteners, when not in direct contact with the wearer s body. Samples exposed to 260 o C for 5 minutes in forced air convective oven, before and after 3 cycles of laundering or dry-cleaning; no melting, dripping, or separation permitted. Applies to fabric, other textile materials, and reflective striping; exceptions include label and emblems, and interlinings, collar stays, elastics, closures, and hook and pile fasteners, when not in direct contact with the wearer s body. Samples exposed to 260 o C for 5 minutes in forced air convective oven; no melting, dripping, or separation permitted; applies to textile materials including visibility trim, reinforcements, wristlets, collar and closure systems, binding and hanger loops; excludes hook and pile fasteners, labels, interfacing and emblems, when not in direct contact with the wearer s body. Heat resistance (hardware) Same as fabrics but must also remain functional Same as fabrics but must also remain functional Heat resistance (primary Same as fabrics closures) Thermal shrinkage resistance Same exposure as above; shrinkage 15% in any one Same exposure as above; shrinkage 10% in any one Same exposure as above; shrinkage 3% in any one Page 3 of 6
