What is the oxygen index test?Oxygen concentration values are known as the Oxygen Index (OI) or, historically, the Limiting Oxygen Index (LOI). The oxygen concentration is measured using a paramagnetic oxygen analyzer and is controlled by varying the relative flow of oxygen and nitrogen through a ve

In November, our customer from a lab in the USA purchased our GD-ISO1182 Building Material Non-Combustibility Tester.

In September, a customer from Norway purchased our GD-1716 Bomb Calorimeter for building material heat of combustion test. We have completed production in late September.

Bomb calorimeter - The calorific value of the sample is measured.

Analysis of the standard operation method of the leakage tracking testerThe Tracking Indices of Solid Insulating Material is used for simulating the tracking index and the tracking index of the leakage resistance of the electrical insulation products and the products of the household electrical appl

Common flame retardancy tests include burn test, limiting oxygen index, glow wire test, smoke test and so on. The purpose of the flame retardant test is to evaluate the combustion characteristics of the material, that is, to test the sample by simulating the actual combustion conditions, and to eval

What is the difference between fire-resistant cables and flame-retardant cables?Fire-resistant cableFire resistance refers to the ability to maintain a certain period of operation in the case of flame combustion, that is, to maintain the integrity of the circuit. This type of cable has a certain tim

flame retardant In order to evaluate the flame retardant performance of the cable, the International Electrotechnical Commission has formulated three standards, IEC60332-1, IEC60332-2 and IEC60332-3. IEC60332-1 and IEC60332-2 are used to evaluate the flame retardant ability of a single cable when it

Cone Calorimeter1. ApplicationCone calorimeters are currently the most ideal test instrument for evaluating the behavior of materials in a fire.2. StandardGB/T 16172-2007ISO 5660-1:20023. Product technical parameters3.1 heating systemCone heater Rated power 5000 W, heat output 0~100 (Kw/m2)Thermoco

Determination of combustion properties in cone calorimeter A plurality of performance parameters of the combustion debris can be obtained using a cone calorimeter, such as heat release rate, mass loss rate, smoke generation rate, effective heat of combustion, ignition time, and toxicity and corrosivity concerning combustion gases. These performance parameters are determined under stable, real, and controllable conditions, and can be repeated at different times and locations. Therefore, it can be used as a reference for literature reference data to provide literature data for more research materials.
