Fire Test Standard for Building Materials (National Standard)
There are many fire test standards for building materials. The R&D technical engineer of (Hong Kong) Co., Ltd. lists the following standards according to the national standard, which is only for each customer's reference. GB 8624-2006 Classification of combustion performance of building materials and products GB 50222-2001 Technical specification for fire protection of interior decoration of buildings GB 20286-2006 Requirements and identification of combustion performance of flame retardant products and components in public places GB/T 2408-2008 Test method for combustion performance of plastics-level Method and vertical method GB/T 8323-2:2008 Test method for combustion performance of plastics Test method for smoke density GB/T 5464:1999 Test method for incombustibility of building materials GB/T 11785:2005 Determination of critical radiation flux of floor coverings Radiant heat source Method GB/T 14402:2007 Test method for calorific value of combustion of building materials GB/T 20284:2006 Single combustion test of building materials or products GB/T 8626-2007 Test method for flammability of building materials GB/T 20285-2006 Material smoke production Toxicity Hazard Classification GB/T 9978-1:2008 Fire Resistance Test of Building Components (ISO 834-1:1999 MOD) GB/T 2408-2008 Test Methods of Plastic Burning Properties Horizontal and Vertical Burning Methods GB/T 8627-2007 Smoke Density of Building Materials Test GB/T 5455-1997 Textiles - Vertical method GB/T 16172-2007 Test method for heat release rate of building materials GB/T 11020-2005 List of methods for the combustion characteristics of solid non-metallic materials exposed to flame sources Rigid foam combustion performance vertical method GB/T 8332-2008 Rigid foam combustion performance horizontal combustion method GB/T 8625-2005 flame retardant test In addition, (Hong Kong) Co., Ltd. is a manufacturer of material testing equipment, and the plastic horizontal and vertical combustion test Take the instrument as an example to explain its applicable standards and main parameters, and welcome customers to inquire. The horizontal and vertical combustion tester is used to measure the flame retardant properties of plastics, rubber, films and other products under the specified fire source to judge the fire resistance level of refractory materials. Applicable standards: GB/T 2408-2008, UL94 V-0 V-1 V-2, GB/T 13488, ISO 1210, ASTM/D 635 4804 3801, IEC707, IEC60695-11-10 standards. Main parameters: 1. Combustion box body: 1) Box body: 0.5m3, machined and formed by CNC machine tool, the arc shape is beautiful and generous, high-quality SUS304 stainless material / baking paint, with beautiful rust and anti-corrosion characteristics. 2) The top of the box is equipped with a ventilation and smoke exhaust system. When the test is completed, the exhaust gas can be discharged to the outside. During the test, the system is in a stopped state. 3) The front of the box is provided with a tempered glass observation window that can be sealed during the test, which is convenient for observing the test situation. 2. Combustion blowtorch: 1) The company's self-made blowtorch fully meets the requirements of IEC60695-11-4: 2004 flame A, B or C. 2) The diameter of the crater: Ф0.95±0.3mm, steam injection port: Ф0.9±0.03mm, the height of the nozzle from the air inlet is 100±10mm. 3) The angle of the torch: 90 degrees horizontally and 45 degrees vertically. 4) Flame height: 20±20. 3. Flame setting time: 0~99 minutes and 99 seconds can be set. 4. Afterflame time: 0~99 minutes and 99 seconds can be set. 5. The remaining burning time: 0~99 minutes and 99 seconds can be set. 6. Test gas: more than 98% methane/37MJ/m3 natural gas (gas can also be used). 7. Burning angle: 20°, 45°, 90°(ie 0°)adjustable. 8. Flame height: according to standard requirements, it can be adjusted from 20mm to 175mm.
In today's world, have risen to an unexpected level of tensile tester manufacturers. It has gained a lot of popularity and has come up with different kinds of variations in its content.
GESTER International Co.,Limited’s core aim is to afford high-quality products with the concept of manufacturing technology.
It's not enough to have an idea as textile testing equipment in a gigantic market. The key to what gets concerned is how you connect this hungry market to the idea that satisfies it.
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,
1. ISO 5402-1: Specifies the flexometer method for testing leather flex resistance under repeated bending.
2. ISO 17694: Defines test methods for footwear upper and lining flex resistance, simulating real-world bending stress to assess long-term durability.
