Australia's comprehensive introduction to the building materials of flame retardant test requirements
AS the 1530 series standard, Australia's comprehensive about building material flame retardant test requirements, specific include:
1, AS1530.1 building materials fire test parts and components - material flammability test;
2, AS1530.2 building materials fire test parts and components - soft, thin film materials flammability test;
3, AS1530.3 building materials fire test parts and components - flammability, flame propagation, the simultaneous determination of heat and smoke;
4, AS1530.4 building materials fire test parts and components - structural components of the flame retardant test;
5, AS1530.7 building materials fire test methods control component parts and components - smoke - and intermediate temperature around the leak test procedure;
6, AS1530.8.1 building materials fire test parts and components - exposed to simulate the bushfire construction component test - radiant heat and small flame;
7, AS1530.8.2 building materials fire test parts and components - exposed to simulate the bushfire construction component test - big flame.
Among them, the AS1530.2 used for soft film materials and textile materials flammability test.
1. The Scope of the Scope
Suitable for wafer or woven fabrics, more soft, just use the hand, and don't need a softening can be stuffed into a sample of the test instrument, use combustion index for performance ratings. The test is not suitable for easy melt, melt condensation products after exposure to fire.
Samples of 2.
18 535 mm * 75 mm
3. The preprocessing
Can be washed or dry-cleaned, carries on the pretreatment, or not, but the pretreatment processing times are determined by the buyer and the seller, there is no hard and fast rules in standard.
Balance of 4.
Samples should be in 20 degrees, 65% RH balance under the environment of not less than 24 hours.
5. Test fire:
0.1 mL of pure alcohol.
6. The test method
(1) the sample vertically, alcohol plate edge: 12.5 mm
(2) in alcohol flame at the bottom of the sample after 160 s, if the fire did not reach a tag line 21, record the maximum height. If the flame arrived before 160 s 21 a tag line, record the time of arrival
(3) using thermocouple thermometer of temperature in the 180 s, the time interval of 1 s.
7. Report
(1) the 160 s when open the maximum height of D
(2) if the flame arrived at a marker line 21, time is less than 54 s, record time.
(3) the temperature and the flue temperature around the area between the two lines between A.
AS1530.3, moreover, the method is used to determine the fire hazard of building materials
Test items include: ignite sex index, flame propagation index, heat release index and index of smoke.
Of ignition index: 20 minus the lighting samples need time, if there are only three of the following sample was lit, criterion of ignition index of 0;
Flame propagation index: from lit sample after irradiation intensity increase the time needed for 1.4 KW/M2 is less than 270 s, is required to determine the actual time to increase the flame propagation index;
Heat index: refers to the sample within 2 minutes, instantaneous irradiation intensity and the difference between the sample just lit before irradiation intensity to determine the value of the integral, if you have five or more than five sample to be destroyed, the heat index of 0;
Calculate according to the optical attenuation coefficient: smoke and;
Test program: mobile specimen holder, when the test is lit, the sample stop moving. During the trial, at least every 3 s record specimen surface under radiant energy. To determine the time from the trial begins to specimen was lit, and calculated the above four parameters of flame retardant.
Sample request: 600 mm * 450 mm * actual thickness, a total of 9 pieces.
