If windows and doors have been fabricated and tested with Rapierstar screws, can I use alternative fasteners from a different screw supplier?
If alternative fasteners are substituted after fabrication and testing to BSI, PAS24 or other industry standard, new sample windows & doors must be comprehensively re-tested by UK Accreditation Bodies to avoid making your company’s CE Marking and other product certifications void.
