EN 1670:2007 (E) 3 Foreword This document (EN 1670:2007) has been prepared by Technical Committee CEN/TC 33 “Doors, windows, shutters, building hardware and curtain walling”, the secretariat of which is held by AFNOR. This European Standard shall be
13、given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2007, and conflicting national standards shall be withdrawn at the latest by September 2007. This document supersedes EN 1670:1998. CEN/TC 33 have considered previous com
14、ments by CEN/TC 262, thereby replacing this European Standard with a new one based solely on the performance testing of building hardware. The current version has been revised to incorporate clarification of the scope, definitions, requirements and acceptance criteria throughout Annexes A and B. The
15、 current version has also been revised to incorporate new developments in technology for corrosion resistance. The new technology combines specific layers and methods on the surface so that thickness or type of layer are no longer relevant. This European Standard is one of a series of European Stand
16、ards dedicated to building hardware products. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germa

EN 1670:2007 (E) 4 Introduction Corrosion protection alone is not specified in any of the six essen
18、tial requirements of the Construction Products Directive but is an implicit requirement for durability. This European Standard provides for the corrosion resistance of all building hardware, classified according to application. Wherever reference is made to classes they are considered to be technica
19、l classes and not classes according to Article 3(2) of the Construction Products Directive (89/106/EEC). The performance tests incorporated in this European Standard are considered to be reproducible and as such will provide a consistent and objective assessment of the performance of these products
20、throughout CEN Member States. A full contribution to the preparation of this European Standard has been made by the European manufacturers organisation “ARGE“. NOTE This European Standard does not include testing for corrosion by sulfur dioxide which is covered by EN ISO 6988. ? EN 1670:2007 (E) 5 1
21、 Scope This European Standard specifies the requirements for the corrosion resistance of building hardware for doors, windows, shutters and curtain walling. This European Standard provides a method of classification of corrosion resistance of building hardware based on performance in a neutral salt
22、spray test (EN ISO 9227). This European Standard specifies requirements for both coated and uncoated surfaces and five grades of corrosion resistance being laid down in accordance with the different conditions of use grades 1 to 5. A grade 0 is also included for which no requirements have been speci
23、fied. Requirements for levels of corrosion resistance which are higher than those laid down for grade 5 have not been included in this European Standard and are subject to agreement where required. This European Standard also applies to the metal fasteners required for fixing building hardware if sp
24、ecified. Screws and fastenings which are sold with a hardware product which conforms to this European Standard should also conform to this European Standard. NOTE 1 The term “grade“ used in this European Standard corresponds to the term “class“ which is used in ISO standards. NOTE 2 There is seldom
