Test method for flammability of flame retardant materials1. Determination of decomposition temperatureThe decomposition temperature of plastics is generally determined according to the method specified in ISO 871-2006 (GB/T 4610-2008).According to the definition of this standard, the decomposition t
Investigate Factors for the Reaction of Materials to FireReaction to fire is an important feature for evaluating the fire performance of materials. Fire protection regulations usually consider the following factors:Flame spreadBurning drippingHeat releaseSmoke production: opacity and toxicityCone Ca

This week we completed our Indonesia customer's order for BS 476-4 Non-combustibility tester and Small Formaldehyde VOC Environmental Test Chamber.Non-combustibility tester comples with ISO 1182, BS 476-4 test standards. Formaldehyde VOC Environmental Test Chamber complies with JIS A 1901.
Cable Corrosion Tester for IEC 60754-1 and IEC 60754-2Cable corrosion tester includes the Electric control box, Heating furnace, Electromagnetic stirrer, Conductivity meter, and PH meter. It complies the IEC 60754-1 and IEC 60754-2. It is suitable for the acidity of the gas released by the materials
The flammability UL 94 rating is the most widely used plastic material flammability performance standard. It is used to evaluate the ability of a material to extinguish after being ignited. According to the burning speed, burning time, anti-drip ability and whether the drops are burning, there are many ways to judge. Many values can be obtained for each tested material according to color or thickness. When the material of a certain product is selected, its UL rating should meet the thickness requirements of the wall part of the plastic part. The UL rating should be reported together with the thickness value. It is not enough to report only the UL rating without the thickness.
Our horizontal and vertical combustion tester can fully meet the testing requirements of UL94, IEC 60695-11-10 and IEC 60695-11-20.
The flame retardant grades of plastics are gradually reduced from V-0, V-1, V-2 to HB:
V-0: After the sample is subjected to a 10 second combustion test twice, the flame is extinguished within 30 seconds. No burning objects should fall.
V-1: After two 10-second burning tests on the sample, the flame goes out within 60 seconds. No burning objects should fall.
V-2: After two 10-second burning tests on the sample, the flame goes out within 60 seconds. There may be burning materials falling.
HB: The lowest flame retardant grade in UL94 and CSA C22.2 No 0.17 standards. It is required that for samples with a thickness of 3 to 13 mm, the burning rate is less than 40 mm per minute. For samples less than 3 mm thick, the burning rate is less than 70 mm per minute, or extinguished before the 100 mm mark.
