Testing laboratory

The HEICO group's in-house testing lab provides support in the development of new and innovative products for bolted connections. Existing products are constantly tested according to current guidelines (e.g. 25201-4, DIN EN ISO 16047), both in-house and also by independent test institutes (e.g. IMA Dresden, Fraunhofer IPA, DIBt). The test lab also offers various test options to check the use of HEICO products for customer-specific installations. By providing technical support and conducting experimental tests directly in the presence of the user, optimum safety can be ensured in individual customer applications.
