Accredited Services

The Czech Institute for Accreditation granted the PIB Certificate of Accreditation in 2002 authorizing the use of the status of an accredited testing laboratory. Most recently in 2022 re-accreditation was carried out and the list of tests for which the testing laboratory is accredited was expanded. These accredited tests are listed in the following table:
