DGUV V3 inspection labels - which ones actually work?
Inspection labels record a passed DGUV V3 test directly on the equipment and flag the next due date. This guide shows how to display the test date, tester name and tamper protection, and which label material suits each environment.

DGUV Regulation 3 requires recurring testing of fixed and portable electrical equipment to DIN VDE 0701‑0702. The inspection label is the visible proof on the device: it confirms the test was passed and states when the next test falls due.
The label does not replace the test report, it complements it. The full result with measured values stays documented, while the label on the equipment gives a fast visual check of whether the interval is still valid.
- Test date or month and year the test was carried out.
- Next test as a due date or period.
- Tester name or initials of the qualified person.
- Clear link to the equipment, ideally via a device or asset number.
How are test date, tester and interval shown?
Common inspection labels use a pointer system: months and years run around the edge and are marked by punching, a hole or a cut-out. This marks the next test permanently and smudge-free, so the print cannot fade away.
Which material and which tamper protection?
The carrier material decides durability and forgery resistance. Polyester and vinyl films withstand cleaning, oil and UV, while plain paper only suits dry indoor use. Tamper-evident labels add a higher level of security.
- Polyester: temperature stable from roughly -40 to 150 °C, oil and solvent resistant.
- Vinyl: flexible for curved surfaces like cables and round housings.
- Overlaminate: a clear protective layer over the label against abrasion.
- VOID labels: leave a visible checkerboard pattern when removed.
Frequently asked questions
Is an inspection label mandatory under DGUV V3?
What is required is documentation of the test, usually as a test report. The label on the device is not strictly compulsory but is standard practice, because it shows the next due date at once and simplifies assignment.
What belongs on the inspection label?
At minimum the date of the passed test and the next due date. In practice the tester name or initials of the qualified person and a unique equipment number are added as well.
How often must equipment be tested?
Intervals depend on the device and its use. Portable office equipment is often tested every 24 months, on construction sites every 3 months. The actual interval follows from the risk assessment.
What does tamper-evident mean for inspection labels?
Tamper-evident labels cannot be removed without a trace. VOID films leave a pattern in the adhesive and on the surface, so any unauthorised removal is immediately noticeable.
