The main standards for a single vertical combustion testing machine include:
national standard:
GB/T 18380.11: Combustion test of cables and optical cables under flame conditions, Part 11: Vertical flame spread test for single insulated wires and cables, test apparatus. This standard specifies the requirements for testing equipment to ensure consistency of testing conditions.
GB/T 18380.12: Combustion test of cables and optical cables under flame conditions, Part 12: Vertical flame spread test for single insulated wires and cables, 1kW premixed flame test method. This standard provides a detailed description of the specific method for conducting tests using a 1kW premixed flame.
Other relevant standards such as GB/T 18380.1, GB/T 5169.14, etc. may also be referenced, depending on the specific needs and purposes of the experiment.
International standards:
IEC 60332-1: Combustion test for cables and optical cables under flame conditions, Part 1. This is a standard developed by the International Electrotechnical Commission (IEC), which corresponds to the GB/T 18380 series of standards and provides internationally recognized testing methods.
These standards specify the requirements for the design, manufacturing, testing conditions, and testing methods of a single vertical combustion testing machine to ensure the accuracy and reliability of the test results. In practical applications, the testing machine should meet the requirements of these standards and be able to conduct tests according to the methods specified in the standards.
