Type tests (short for Prototype) are predominately destructive tests, conducted to determine if the cable construction and materials are compliant with standard specifications. As inferred in the name, prototype tests are done to prove design and the required cable parameters – they are only required to be done once and are generally not repeated.
Examples of type tests include:
- Corrosive and acid gas
- Mass of zinc coating for galvanized wire armored
- Smoke emission
- Flame propagation test for multiple cables
- Shrinkage test on insulation
- Abrasion test
Type tests, routine tests, or sample tests are categorized in the relevant standard to which the cable is manufactured to.
