The material is classified as Class A, Class B or Class C according to the ASTM E84, providing the mandatory fire‑safety data for the interior‑finish and the building‑material acceptance. This fireproof and flame retardant bag testing plan verifies that the bag fabric will not contribute significantly to the fire growth in the storage or the occupancy environments.
- Euroclass reaction‑to‑fire classification according to EN 13501‑1 (Fire classification of construction products and building elements) using the data from the EN 13823 Single Burning Item (SBI) test and the EN ISO 11925‑2 small‑flame ignitability test: the bag material or the complete bag is mounted on a calcium‑silicate or a gypsum‑board substrate in the SBI room‑corner test, and the fire‑growth‑rate index, the total heat release, the lateral flame spread and the smoke‑growth‑rate index are measured. The product is classified as A2‑s1,d0, B‑s1,d0, C‑s2,d1 or a lower class, as required by the national building regulation for the interior‑lining materials of the European Union.
- Measurement of the heat‑release rate, the effective heat of combustion and the mass‑loss rate by the cone‑calorimeter method according to ISO 5660‑1 (Reaction‑to‑fire tests – Heat release, smoke production and mass loss rate) and ASTM E1354: a specimen of the bag material is exposed to a defined radiant‑heat flux of 35 kW/m² or 50 kW/m², and the ignition time, the peak heat‑release rate, the total heat released and the specific extinction area (the smoke parameter) are reported, providing the fundamental fire‑hazard data that the risk‑assessment engineer uses to model the contribution of the bag to a developing compartment fire.
- Vertical‑burn and the horizontal‑burn testing according to UL 94 (Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances, adapted for the textile and the composite materials) and the IEC 60695‑11‑10: the bag fabric is subjected to a defined 50 W or 20 mm gas‑flame, and the after‑flame time, the after‑glow time and the dripping‑ignition of the cotton indicator are recorded, providing the V‑0, the V‑1, the V‑2 or the HB flammability rating that is required for the electrical‑enclosure, the appliance‑component and the consumer‑product safety certifications.
- Small‑flame ignitability and the edge‑ignition testing according to EN ISO 11925‑2 (Reaction to fire tests – Ignitability of products subjected to direct impingement of flame): the surface and the edge of the bag material are exposed to a small propane‑gas flame, and the ignition, the flame‑spread to the 150 mm mark and the flaming‑droplet production are assessed, providing the supplementary ignitability data that are required for the Euroclass classification.
Mechanical Strength, Puncture Resistance and Durability – Fireproof and Flame Retardant Bag Testing According to ASTM D5034, ISO 13934‑1 and ASTM D4833
