Test stickers Test stickers are used as part of quality assurance (QA) DIN ISO 9000 ff and, for example, for legally required inspections and accident prevention (UVV). This applies in particular to the monitoring of test equipment, devices and systems as well as important supply lines (cables, pipes). You have two options for attaching the test stickers: directly on the device being tested or on one of the basic stickers offered, which is stuck onto the device. The test date is marked with a pen or notching pliers. The test stickers are made of forgery-proof document film, i.e. to protect against misuse, the sticker is irreversibly destroyed if anyone tries to remove it. Properties of the document film: The document film can be written on with a pencil, ballpoint pen, fiber pen or typewriter. It is 0.05 mm thick and is temperature-resistant from 30 degrees C to +80 degrees C. The adhesive strength is higher than the tear resistance of the film. It breaks when removed and is largely resistant to aging, weathering and light. It is also resistant to water, sea water, alcohol, aliphatic solvents and petroleum-based oils and fats. Flash red
