Scope: ASTM E1725-19 test method covers fire-test-response that provides the information on the temperatures recorded on the electrical system component within a fire-resistive barrier system during the period of exposure. Test Procedure: In ASTM E1725-19, the average air temperature inside the fire-resistive barrier system at the beginning of the test is not less than 50°F...
Scope: ASTM E794 – 06 is useful for quality control, specification acceptance, and research. The fusion and crystallization temperatures of crystalline materials can be determined quickly using differential scanning calorimetry and differential thermal analysis. Procedure ASTM E794 – 06 entails heating a test specimen at a regulated rate through the fusion area in a controlled...
Scope: THE ASTM E576-08 test method can be used under real-world or simulated in-service situations. One side of the unit is exposed to room temperature and the other to natural or simulated weather conditions. Procedure: This test is carried out with the help of a unique apparatus that consists of two cold cylindrical metal blocks...
Scope: ASTM E285-08 test method covers the screening of ablative materials to determine the relative thermal insulation effectiveness. This test method is used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions. Test Procedure: In ASTM E285-08 test method, hot combustion gases are...
Scope: Electrical equipment such as wires, resistors, and other conductors, may overheat under certain conditions of operation or when they malfunction. Overheating can result in the ignition of the neighboring insulation material. ASTM D6194-18 test method evaluates the susceptibility of electrical insulating materials to ignition when exposed to a glowing wire. This test method determines...
Scope: ASTM D2520 is useful for specification acceptance, service evaluation, manufacturing control, and research and development of ceramics, glasses, and organic dielectric materials. Complex permittivity (dielectric constant and dissipation factor) is an important value used in designing transmission lines, resonators, antennas. Dielectric constant is the measure of the amount of potential energy stored due to...
Scope: ASTM C518 is a quick way to determine Steady-State Thermal Transmission properties that guide the design and prototyping of electronic products. Steady-State Thermal Transmission properties of a material change with temperature change. It is important for designing electronics that dissipate fixed amounts of heat in a given time. This ensures that the device stays...
