A mask flame Retardant tester is a specialized testing device used to evaluate the flame retardant performance and combustion behavior of masks when exposed to open flame or high-temperature flame conditions.
Under specified conditions, a standard flame is applied to a mask specimen to determine:
Whether ignition occurs
Whether sustained combustion occurs
Burning duration
Flame spread behavior
Whether melting, dripping, or ignition caused by molten droplets occurs
Based on these observations, the tester is used to assess the safety risk level of mask materials when exposed to fire sources in use or accident scenarios (such as medical or industrial environments).
Essential characteristics:
Belongs to flammability / flame retardancy testing equipment
An important component of the personal protective equipment (PPE) testing system
Commonly used in medical protection, emergency protection, and quality supervision testing
(1) Quality control of medical protective masks
Medical surgical masks
Medical protective masks
Medical disposable masks
Used to verify the safety of masks in environments with potential ignition sources such as surgical procedures, electrosurgery, and laser equipment.
(2) Testing of respiratory protective equipment
Dust masks
Particulate respirators
Protective face masks (certain structural materials)
Flame retardant performance serves as an important supplementary indicator of protection level.
(3) R&D and material screening
Evaluation of flame-retardant modification of meltblown fabrics
Comparison of flame-retardant formulations for nonwoven fabrics
Study of combustion behavior of multilayer composite structures
(4) Third-party testing and certification bodies
Product type testing
Standard compliance verification
Supervisory sampling inspection and quality arbitration
Basic testing concept
Under controlled conditions, the mask specimen is exposed to a specified flame source, and its combustion response is observed and measured to evaluate flame retardant performance.
Core working principles
(1) Flame generation system
Typically uses butane or propane gas
Flame height, angle, and application time are adjustable
Flame stability is critical for test repeatability
(2) Specimen support and positioning system
The mask is fixed at a specified angle (e.g., vertical or inclined)
Ensures consistent flame application position
Prevents specimen movement during testing
(3) Combustion behavior monitoring
Record whether ignition occurs
Record burning duration
Determine whether dripping, melting, or smoldering occurs
(4) Timing and result determination
Burning time is measured using a timer
Results are compared with standard limit values
A “Pass / Fail” conclusion is output
This type of instrument is typically a phenomenon-based testing device, with standardized operation and repeatability as the core focus.
Mask flame retardancy testing does not usually correspond to a single independent standard, but commonly references or adopts flammability standards for protective clothing and personal protective equipment.
Relevant domestic standards (commonly referenced)
GB 19083 Technical Requirements for Medical Protective Masks
Clearly requires that mask materials possess a certain level of flame retardant performance.
GB 2626 Respiratory Protection — Non-powered Air-purifying Particulate Respirators
Involves material safety and combustion risk.
GB/T 5455 Textiles — Burning Behavior — Vertical Method
Commonly used as a reference test method.
International and industry reference standards
EN ISO 6940 / EN ISO 6941
Textile flammability (surface / vertical flame spread)
16 CFR Part 1610 (applicable to certain materials)
ISO 15025 Protective clothing — Limited flame spread testing
In practical applications, mask flame retardancy testers are usually customized or expanded based on the “textile flammability testing logic.”
Pre-test preparation
(1) Gas supply inspection
Correct gas type (butane / propane)
No leakage in gas lines
(2) Instrument status check
Ignition system functioning properly
Timer reset to zero
Specimen fixtures clean
(3) Specimen preparation
Specimens cut according to the standard or tested as complete masks
Specimens free of wrinkles and contamination
Record specimen identification numbers
Test procedure
(1) Specimen installation
Fix the mask onto the specimen holder
Ensure the test area is unobstructed
(2) Flame parameter adjustment
Flame height meets standard requirements
Flame positioned at the specified distance from the specimen
(3) Ignition and flame application
Flame contacts the specified area of the specimen
Maintain the specified flame application time (e.g., 1–3 s)
(4) Observation and timing
Whether ignition occurs
Burning duration
Whether self-extinguishing occurs
Whether melting, dripping, or flame spread occurs
(5) Result recording
Complete test records
Mark any abnormal phenomena
Operating environment requirements
Good ventilation
No flammable or explosive materials nearby
Fire extinguisher available
Standard operating procedure (SOP)
(1) Power-on and inspection
Connect the power supply
Check gas line sealing
(2) Flame calibration
Adjust flame height
Confirm flame stability and correct alignment
(3) Specimen testing
Test each specimen independently
Repeat according to the required number of test cycles in the standard
(4) Result determination
Burning time ≤ standard limit value
No sustained combustion permitted
No hazardous molten dripping allowed
(5) Test completion
Shut off gas supply
Clean combustion residues
Record and archive test data
Safety precautions
Operators must be trained
Do not leave the test unattended during operation
In case of abnormalities, immediately shut off the gas supply
