BS EN 1670:1998 PDF

Scope: This European Standard specifies the requirements for the corrosion resistance of hardware for doors, windows, shutters and curtain walling. The standard specifies requirements for both coated and uncoated surfaces, four grades (classes) of corrosion resistance being laid down in accordance with the different conditions of use [grades (classes) 1 to 4]. A grade (class) 0 is also included for which no requirements have been specified. Requirements for levels of corrosion higher than those laid down for grade (class) 4 have not been included in this standard and are subject to agreement where required. This standard also applies to the metal fasteners required for fixing building hardware. The requirements for protective finishes specified in this standard are derived from ISO standards. Where materials are used uncoated or where other finishes are used that are not covered by ISO standards, classification is based on performance in neutral salt spray tests as specified in ISO 9227. NOTE The term "grade" used in this European Standard corresponds to the term "class" used in ISO standards.
