The KR‑2522 mask flammability assessment unit is dedicated PPE laboratory apparatus for evaluating flame‑retardant characteristics of medical and respiratory protective masks. Under defined linear‑speed motion, a mask mounted on standard metal head‑form makes controlled contact with calibrated high‑temperature flame source. The instrument records after‑flame duration and smouldering time, to judge whether mask material meets anti‑ignition safety thresholds.
This enclosed‑chamber test rig reproduces accidental flame‑exposure scenarios encountered in real‑world application. It supports compliance verification for medical surgical masks, medical protective respirators and particulate protective masks. Widely implemented in mask‑manufacturing enterprises, medical‑device‑inspection institutions, occupational‑safety‑laboratories and accredited third‑party PPE‑testing‑organizations.

Standard Complete Test Operating Workflow
- Pre‑Test Preparation
Place tester on stable horizontal lab‑floor. Connect main power‑supply and propane gas‑supply pipeline, check gas‑joints for leakage. Power‑on unit, warm‑up instrument. Adjust burner flame‑height, calibrate flame‑temperature to 800 ± 50 ℃. Configure linear‑moving‑speed, pre‑heat interval via touch‑screen interface.
- Specimen Mounting
Fit mask test‑sample firmly onto metal dummy‑head form, simulate normal wearing tension and position. Adjust head‑form height so vertical gap between mask lowest‑edge and burner nozzle meets standard‑required 20 ± 2 mm dimension. Close and lock test‑chamber door.
- Execute Flammability Test Sequence
Ignite gas‑burner, start test‑run command. Motor‑driven translation system drives head‑form assembly to pass mask surface across calibrated flame source at set linear‑speed. After completing flame‑contact procedure, burner moves back to standby‑position. System automatically records after‑flame burning time and smouldering duration.
- Observation & Result Evaluation
Observe mask combustion behaviour through viewing window. Record ignition status, after‑flame time and smouldering‑time readings. Compare measured‑data against standard‑limit values to complete pass‑fail judgement for mask‑sample.
- Post‑Test Tidying
Shut‑off gas‑supply valve firstly. Wait for burner and internal cabinet components to fully cool‑down. Remove burned mask‑residues, clean soot inside test‑chamber. Cut‑off main‑power‑supply. Periodically inspect gas‑pipeline integrity, temperature‑probe condition and timing‑module accuracy.

Safety‑Operation‑Reminder
Strictly follow flammable‑gas safety‑regulations, inspect gas‑pipe‑sealing before ignition. Do not open test‑chamber‑door during burning‑test‑execution. Ensure good lab‑ventilation for smoke exhaust. Allow sufficient cooling‑period before cleaning internal‑chamber after‑test‑run. Reliable equipment grounding must be completed prior to power‑on.
