Mutual recognition of testing standards for fiber-reinforced flat-sheet cement boards is facilitated through international agreements and accreditation frameworks. These frameworks ensure that test results from accredited laboratories are accepted across different countries, streamlining compliance with various national construction codes.
INTERNATIONAL ACCREDITATION RAMEWORKS:
INTERNATIONAL LABORATORY ACCREDITATION COOPERATION (ILAC): ILAC is a global network of accreditation bodies that recognize each other’s accreditations through the ILAC Mutual Recognition Arrangement (MRA). This arrangement promotes the acceptance of test and calibration data across national borders, reducing the need for duplicate testing.
ASIA PACIFIC ACCREDITATION COOPERATION (APAC): APAC is a regional body that operates a mutual recognition arrangement among accreditation bodies in the Asia-Pacific region, supporting the acceptance of accredited conformity assessment results.
