Supersession
This part of BS 6375 supersedes B5 6375-1:2009 which is withdrawn.
Relationship with other publications
BS 6375 is published in three parts:
●Part 1: Classification for weathertightness and guidance on selection andspecification;Part 2: Specification for operation and strength characteristics;Part 3: Addlitional performance characteristics.
It is related to the European product standard for windows and external pedestrian doorsets BS EN 14351 1) (see also Information about this document).
Information about thisdocument
This is a full revision of the standard and introduces the following principal:abueqp
The method of calculating wind load in Annex A has been revised. It is now required to use either the method specified in BS EN 1991-1-4:2005 and theNational Annex to BS EN 1991-1-4 or the abbreviated method which has beenrecalculated in accordance with BS EN 1991-1-4.
BS 6375 has been prepared to provide guidance on the selection of performancecharacteristics for windows and doorsets intended for the UK market. The fullrange of characteristics is provided in the various parts of BS EN 14351.
BS EN 14351 is the harmonized European Standard for windows and external doorsets and is the standard to be referenced if the product is to be CE marked.Not all the characteristics listed in BS EN 14351 are required for CE marking and of those that are required only those mandated (i.e. covered by nationalbuilding regulations) in the UK need be declared.
The majority of characteristics identified in BS EN 14351 have a number ofmanufacturer on an appropriate level for the UK market. This can be by a single performance levels. BS 6375 provides guidance to the specifier and thevalue for a product characteristic or by a value for a particular service condition. For example a doorset in a public building might need to meet a more severelevel of performance for some characteristics than a doorset in a dwelling.
Specifiers are not obliged to use a particular performance level but need to be aware that unnecessarily selecting a more severe performance level can incur acost penalty out of proportion to the performance advantage.
BS EN 14351 and BS 6375 cover a range of products and characteristics and are therefore divided into parts. BS EN 14351 is divided into product groups andBS 6375 is divided into performance characteristics. Not all characteristics will beapplicable to all product groups or to all end uses. In addition BS 6375 may be used for product groups not covered by BS EN 14351.
BS 6375 does not identify a remended performance level for anywindows); these levels are subject to statute. characteristic that is remended in national regulations (e.g. U values for
If a manufacturer wishes to declare a CE marked performance this has to bedeclared against the appropriate part of BS EN 14351. Manufacturers wishing to CE mark products are advised to seek advice from the relevant nationalregulatory authority.
