  • What is the Oxygen index?

    Oxygen index is abbreviated as OI, which is the minimum oxygen concentration required to maintain a stable combustion of a sample in a mixed gas flow of oxygen and nitrogen under specified conditions, expressed as a percentage of the volume of oxygen.
     
    The oxygen index is an expression method to evaluate the relative combustibility of plastics and other polymer materials. It is very effective to judge the difficulty of burning when the material is in contact with flame in the air, so it is valued by countries all over the world. The corresponding oxygen index method standards are GB 2406-80 (plastics) and GB 5454-85 (textiles), ISO 4589-2, ASTM D2863. 

    Our GD-ISO4589 Limited Oxygen Index tester can comply with GB 2406-80, ISO 4589-2 and ASTM D2863. It is     for the determination under the test conditions specified in oxygen and nitrogen gas mixture just to maintain a minimum sample combustion oxygen concentration required.
     
    A high oxygen index indicates that the material is not easy to burn, and a low oxygen index indicates that the material is easy to burn. It is generally considered that an oxygen index <22 is a combustible material, an oxygen index between 22 and 27 is a combustible material, and an oxygen index> 27 is a flame-retardant material.

  • How to define the flame retardant grades of plastics V-0, V-1, V-2 and HB?

    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.

  • Main Difference between BS 476-4 and EN ISO 1182 Building Materials Non-combustibility Test

    Main Difference between BS 476: part 4 and EN ISO 1182
    Building Materials Non-combustibility Test
     
    Many customers have different requirements for the test standards of Non-combustibility testers. Our Non-combustibility tester can be customized according to the needs of customers. It can meet the British standard BS 476 part4, and can also meet the international standard EN ISO 1182. Let's distinguish between these two standards. What is the difference?
     
    Test category: fire test, non-combustibility test of building materials

    The main differences are distinguished from the following six aspects, namely the sample size of the non-combustibility tester, state adjustment, number of thermocouples, furnace temperature stability requirements, test completion judgment conditions and standards for non-combustible materials conformity assessment criteria.
     
    Main difference:
    1. Sample size requirements
    BS 476:part 4: Length and width are 40+0/-2mm, height 50±3mm, volume 80.0±5.0cm3.
    EN ISO 1182: The diameter is 45+0/-2mm, the height is 50±3mm, and the volume is 76±8cm3.
     
    2. Condition adjustment requirements
    BS 476:part 4: 60±5℃ ventilated drying oven for 24h
    EN ISO 1182: 60±5℃ ventilated drying box, adjust 20h to 24h
     
    3. The number of thermocouples required
    BS 476:part 4: 2 pieces (sample center, inside the furnace)
    EN ISO 1182: 3 pieces (sample center, furnace, sample surface)
     
    4. Furnace temperature stability requirements
    BS 476:part 4: The temperature in the furnace should be stable at 750±10℃ for at least 10 minutes.
    EN ISO 1182: The average temperature in the furnace is stable at 750±5℃ for at least 10 minutes. Its temperature drift (linear attenuation) should not exceed 2℃ within 10min, and the maximum temperature difference from the average temperature within 10min should not exceed 10℃
     
    5. Judgment conditions for test completion
    BS 476:part 4: 20 minutes
    EN ISO 1182: When the temperature measured by all thermocouples does not change more than 2°C within 10 minutes within 30 minutes, it is considered that the final temperature equilibrium has been reached and the test will stop. If the temperature obtained by the thermocouple does not reach the final temperature equilibrium within 30 minutes, the test should be continued; at the same time, the final temperature equilibrium should be checked every 5 minutes. When the thermocouple reaches the final temperature equilibrium or the test has been conducted for 60 minutes, stop the test and record the duration of the test. Then, take out the sample from the furnace. The end of the last 5min interval or 60min is the end of this test.
     
    6. Conformity assessment criteria for non-combustible materials
    BS 476:part 4: The temperature rise of the highest temperature in the center of the test piece relative to the initial furnace temperature is ≤50℃, and the temperature rise of the highest temperature in the furnace relative to the initial furnace temperature is ≤50℃, and the flame duration is ≤10 s
    EN ISO 1182: Class A1 (EN 13501-1:2007) The temperature rise of the highest temperature in the furnace relative to the final equilibrium temperature in the furnace △T≤30℃, and the mass loss △m≤50%, and the continuous flame time tf= 0 (No continuous combustion) Class A2 (EN 13501-1:2007) The temperature rise of the highest temperature in the furnace relative to the final equilibrium temperature in the furnace △T≤50℃, and the mass loss △m≤50%, and the continuous flame time tf ≤20 s

  • BS476-4 flame retardant performance test standard content of non-combustibility tester

    Hong Kong or the United Kingdom often use the BS476-4 non-combustibility requirement as the standard for evaluating the flame retardant performance of materials. Therefore, we should first understand the non-combustibility evaluation requirements in order to better adjust the product performance to meet the requirements.
     
    Test Standard of Non combustibility Tester:
    BS 476-4: Fire tests on building materials and structures- Part 4: Non-combustibility test for materials
     
    Ttest sample size of Non-combustibility Tester:
    40mm*40mm*50mm
     
    Introduction to the BS476-4 non-combustibility test process:
    After the sample is adjusted in a ventilated drying oven at 60±5℃ for 24h, it is put into the test container, a thermocouple is inserted into the center of the sample to record the temperature change, and the other thermocouple is put into the furnace to record the temperature change. The temperature in the furnace is stabilized at 750±10℃ for at least 10 minutes, and the whole test is 20 minutes, and the relevant data of the two thermocouples are recorded.
     
    BS476-4 non-combustibility test and evaluation requirements of non-combustibility tester:
    1. The temperature rise of the two thermocouples must be less than 50℃.
    2. The flame burning time during the test must be less than 10s.

  • What size specimen is tested in ISO 1182 Non-combustibility Test?

    Q: What size specimen is tested in ISO 1182 Non-combustibility Test? 

    A:  The test specimen shall be taken from a sample which is sufficiently large to be representative of the product.
    The test specimens shall be cylindrical and each shall have a diameter of 45mm and a height of 50 mm,

  • How do I know if a classification document covers a certain product?

    A classification document must contain the product name and product description including:
    • thickness
    • colour
    • mass per unit area or density of the product
    • application rate and application method for an applied chemical product
    • mounting and fixing
    • air gap
    • substrate
    • edge testing
    • joint testing
    Some product description information may be contained in the test reports, and not the classification document. If this is the case you must ask to see all the relevant documentation to be sure that the classification document relates to the product you wish to purchase.

  • Does the wood product I want to install have a European Class D without further testing?

    Wood and wood-based products achieve a classification without the need for further testing providing they meet certain criteria. These criteria are listed in the relevant European Commission Decision.

    Copies of these Commission Decisions are available for free via the internet. To use a Commission Decision to find the performance of your product you will need to know the density, thickness and end use condition for your product. You may also need to know mounting or profile details, and be able to check if your product conforms to the relevant product standard. You should check your product against these criteria as listed in the table in each Commission Decision. This table will also tell you the relevant reaction to fire classification.

    If your product does not meet the conditions listed in the table, you will need to determine the product’s reaction to fire performance through testing.
     

  • What is a classification document?

    A classification document is produced using the product's test reports. It is the classification, and not the test reports that demonstrate the classification of the product. It is the classification document that a manufacturer will show to customers and enforcers to demonstrate compliance with the regulations. If you want to check the product you are purchasing meets your requirements for reaction to fire, you must see a classification document to EN 13501-1.

  • Do any materials get a classification without testing?

    Yes, some materials for which there is a lot of historic data, such as wood and metal can in some cases be classified without testing. The Building Regulations provide details for “typical performance ratings of some generic materials and products”.  European Commission decisions can also be used in some instances, see FAQ 19 for details on this.
