Visual test
Visual check is the most important and effective part of a machine test.
Electrical testing often does not disclose failures that become apparent on visual
inspection. A visual check must be carried out before each electrical safety test.
Following items should be checked:
- Wiring connection points. Especially PE connections are important!
- Protection covers, housings.
- Inscriptions and markings related to safety must be clearly readable.
- Cable layout, radiuses, isolation.
- Switches, regulators, lamps, keys.
- Parts subjected to wear out.
- Electrical and mechanical protection devices (barriers, switches, fuses, alarms).
- Openings, filters.
- Technical documentation, availability of instructions for use.
- Installation of the DUT must be performed according to the Instruction manuals.
During visual inspection the measuring points for the electrical testing have to be
determined too.
Check that there are no signs of:
- Damage,
- Pollution, moisture, dirt that can influence the safety,
- Corrosion,
- Overheating.
