KEYSTONE, the US inspection agency, has recognized our tests on glass doors, windows, and curtain walls

(Pubbl. 25/07/2019)
Istituto Giordano, as a laboratory already accredited by ACCREDIA for ISO/IEC 17025, has been recognized by KEYSTONE, the US Certification Body, for environmental (water, air, and wind), burglar resistance, and structural performance tests on glass doors, windows, and curtain walls based on ASTM and AAMA standards.

The only laboratory outside the US and Canada to have obtained such recognition. 

This means that any European company can be certified with Keystone by conducting performance tests at Istituto Giordano’s Italian laboratories, thereby making their product more attractive for the US market.

Details on normative references:

This recognition is in addition to the one that Istituto Giordano has received from NAMI, the National Accreditation & Management Institute, in New Orleans, LA (USA).
