The DGUV Test symbol certifies that machines from Poly-clip System meet the relevant health and safety requirements. The DGUV Test symbol is a voluntary test symbol first introduced in 1984, when it was known as the BG symbol. In addition to (type) testing, production control is an essential component of the certification programme. The awarding authority is DGUV (German Social Accident Insurance). A certificate conferring use of the DGUV Test symbol remains valid for a maximum of five years. In this way, the currency of the symbol and thus the consistency of safety-related requirements, is ensured. Every DGUV Test symbol contains the shortened form of the testing and certification authority awarding the DGUV Test symbol, along with the relevant certificate number.
