Do you know what routine tests are (production line tests) and what they are for?

Routine tests are conducted in the units of a production batch, following established performance procedures and under current testing standards. Its main objective is to ensure that the manufacturing and assembly processes comply with and maintain the specified quality without introducing imperfections or faults in the items produced, including checking the level of conformity between parts and pieces of the same project.

The main safety-related routine tests are:

Dielectric strength

It is a withstand voltage test on the production line applied to the unit under test. It shall withstand, without an indication of unacceptable performance, the application of a predefined potential.

Ground continuity

This test is applied to groundable production units through fixed wiring or a power supply cable with a grounding conductor to determine ground continuity between the ground connection point and accessible non-working metal parts that are likely to become energized.

Leakage current

This test indicates the flow of abnormal or unwanted current in an electrical circuit due to a leak, usually a short circuit or an abnormal low impedance path, which can result in electric shock when the energized unit is handled.

And related to performance it is:

Functional

The functional performance test verifies whether the final product meets the specifications established at the beginning of the project and whether the product is suitable for use. Test procedures shall be established to ensure that the results obtained are reliable.

These routine or production line tests shall be specified by the manufacturer following applicable regulations and standards, depending on the product type and its construction project.

Implementing routine or production line tests is a very effective way of mitigating various risks related to the safety and use of the product after its manufacture.

Routine tests can be performed on 100% of the items produced or on a sample basis, considering statistical techniques to validate the result of acceptance or rejection of an item after conducting routine tests.

Thus, the application of routine tests or tests on the production line is a good practice for verifying the efficiency of production as well as maintaining the specifications designed for the product.
