Today we are together and we look for a mattress flammability testing standard. First, we first look at the standard of our country, China's current standards on the flame retardancy of the existing mattress for the evaluation of 17927- > GB 1999< upholstered furniture spring mattress and sofa anti ignition characteristics, the standard is applicable to the hotel the use of family and other occasions, the spring mattress and the sofa. Specified in the standard, at the temperature of 15 DEG ~25 DEG 40%~70%, relative humidity, air flow rate (0.02~0.2) test in the m/s environment. The lit incense smoke along the specimen surface elevation and level of the binding site, and close to the facade (most likely to ignite the mattress or other parts, such as seam inside and wire harness and other local pits such as depression), at the same time start time. In the 1H, if the observed detection sites of smoldering or flame combustion phenomenon, then the test pieces Did not pass the test; if not found the phenomenon, in the new position to repeat test; if it has not been observed this phenomenon, is the final check, immediately open the specimen, the specimen to check whether the internal smoldering phenomenon. If no smoldering phenomenon, then through the test specimen, or did not pass the test. Of course, GB 20286- 2006< public places of flame retardant products and components, combustion performance requirements and marking > on the bed, the use of indoor public places mattress, sofa and other furniture and combustion properties of components of the proposed requirements, fire flame retardant grade 1 upholstered furniture standard to judge the peak heat release rate is less than 150KW, the total energy is less than or equal to 30MJ in the 5min release, maximum smoke density the fire retardant is less than or equal to 75%; grade 2 upholstered furniture standard to judge the peak heat release rate is less than 250KW, the total energy is less than or equal to 40MJ in the 5min release, for the whole combustion specimen.

Secondly, we look at the relevant provisions of the EU flammability testing, the European standard EN 597- 1< furniture - mattresses and bed based combustion performance evaluation 1 ignition source smouldering cigarette and EN 2< furniture - > 597- mattress and soft beds based combustion performance evaluation of 2 fire: fire and matches, the same in the clear requirements > flame the mattress by the smouldering cigarette test and combustion test. Namely: the cigarette or flame respectively at a distance of other test traces or mattress edge 50mm or 100mm position parallel and close to the mattress (especially considering the inside seams and harness local pits such as depression), at the same time start time and observe the smoldering or burning phenomenon. If the observed detection sites of smoldering or flame combustion phenomenon, then the specimen did not pass the test; if not found the phenomenon, in the new position to repeat test; if it has not been observed in the phenomenon. At last check, immediately open the specimen, the specimen to check whether the internal smoldering phenomenon. If no smoldering phenomenon, then through the test specimen, or did not pass the test. In addition, the EN 1021- 1- 2006< furniture - Assessment of the ignitability of upholstered furniture 1 ignition source smouldering cigarette "and" furniture - assessment of the ignitability of upholstered furniture 2 fire: fire and matches, >EN 1021- the same 2:2006 flame mattress filler will require respectively by the smouldering cigarette test and open fire burning test, the testing process with EN 597- 1 and EN 597- 2 are basically the same.

Finally, we look at the American Standard, their standard requirements for flame retardant is composed of two parts: 16CFR1632< mattress and cover flammability standard > and 16CFR1633< mattress flammability requirements. In the frame and standard for the flammability of 16CFR1632 using nonfiltered natural tobacco as a point source, 18 flame retardant test cigarette at least every mattress, 9 "(Bare mattress tests bare mattress test)" and 9 "double bed test (Two sheets tests). The requirements of laws and regulations, the 6 mattress surface must be all through the test, otherwise the mattress unqualified.16CFR1633 sets two criteria to limit the flame in the mattress or mattress set the spread of these two indicators is the use of two T type burner, at the specified location, the upper surface of a burner flame sprayed onto the mattress, another burner flame sprayed into the bed pad and pedestal The side. One is in, in free burning 30mins fuel propane gas peak heat release rate of spray, shall not exceed 200KW; two is the first 10mins, the total heat release shall not exceed 15MJ.
