Test methods and standards for flame retardancy



All flame retardancy testing methods are described in the relevant standards. Testers should select the appropriate regulatory standards for testing according to the type of test items and the requirements of the place of export. If both the purchaser and the local government have requirements, the test will be carried out according to high standards.

(1) Test methods and standards for flame retardant properties of plastics

1. Test methods and standards for flammability of plastics (UL94 flammability test)

2. DETERMINATION OF LIMIT OXYGEN INDEX OF PLASTICS

3. Measurement of smoke production (smoke density method)

(2) Test Method for Combustion Characteristics of Automotive Interior Materials

FMVSS-American Federal Automobile Safety Standard

SAE-American Association of Mechanical Engineers

ISO 3795 - International Standard

GB 8410-China National Standard

And Honda, Nissan, Mitsubishi, Volkswagen, BMW, General Motors and so on have their own standards.

(3) Fire hazard test methods for electronic and electrical products

Due to faults, abnormal use or wrong operation of live circuit, the phenomenon of excessive temperature, short circuit, flashover and so on will be caused, which will lead to the possibility of fire. Common test methods are:

· Test method for hot wire

Scorching wire test

。

· Needle Flame Test Method

IEC and GB/T have corresponding regulations.

(4) Summary of test methods for combustion performance of building materials

· Combustion Testing of Building Materials in USA

ASTM Vertical Furnace Combustion Standard

UBC Standard for Heat Release of Building Materials

Testing of Combustion Performance of ISO Paving Material-Radiant Heat

· Combustion Testing of Building Materials in China

Classification Method for Combustion Performance of GB Building Materials

Combustion Performance Test of GB/T Building Products-Non-combustibility Test

Test Method for Calorific Value of Combustion of GB/T Building Materials

Measurement of Combustion Performance of GB/T Paving Material-Radiation Heat Source Method

(5) Summary of test methods for combustion performance of wires and cables

UL Supply Air Combustion Test/Stern Sodium Channel Test

UL Vertical Combustion

UL Vertical Bracket Test

UL Vertical Combustion Test

UL Horizontal Combustion Test

IEC Vertical Combustion Similar

IEC Determination of Combustion Gas Volume

Horizontal and Inclined Combustion of GB Single Wire and Cable

Fire Resistance Characteristics of GB Wires and Cables

(6) Summary of test methods for fire retardant properties of fire retardant coatings

Relevant test methods

GB decorative fire retardant coatings (suitable for expansive decorative coatings)

There are three common methods: plate combustion, tunnel combustion and chamber combustion.

(7) Test method for combustion performance of furniture mattresses

· Standards for Mattress Flame Retardant Testing

TB mattress cigarettes

Open Mattress Fire (implemented on July 1, 2007)

Open Mattress Fire (1 January 2005)

Open Mattress Fire in High Risk Residence

Open fire on mattress of public residence

ASTM mattress open fire

· Relevant Standards for Flame Retardant Testing of Cushioned Furniture

TB, BS, ASTM, NFPA cushion materials

Cushioned furniture (cigarettes), seats (California mandatory), cushioned models or furniture (cigarettes).

(8) Test methods for combustion properties of textile fabrics

ASTM Common Fabric Combustion Test Method

Standard for testing flame retardancy of tents

Standards of BS, EN, ISO and GB/T on flame spread of textiles

British Pyjamas Burning Test; Children's Pyjamas Test Standard.
