BS 6375-1:2004 pdf free.PERFORMANCE OF WINDOWS AND DOORS – PART 1: CLASSIFICATION OF WEATHERTIGHTNESS AND GUIDANCE ON SELECTION AND SPECIFICATION.
BS 6375-1 specifies the exposure categories related to test pressure levels for air permeability, watertightness and wind resistance for external windows and doors. It is applicable to all types of vertical windows and doors, and includes windows in which the opening lights are not fully framed, e.g. adjustable glass louvres.
The standard excludes patent glazing (see Note) and curtain walls that span across horizontal structural members of floors but includes the opening lights within a vertical patent glazing or curtain walling system.
An abbreviated method for calculating wind loading is given in Annex A. This takes into account factors that allow selection and specification of the appropriate classification.
NOTE Recommendations for the design and installation of patent glazing are given in BS 5516.

4 Exposure category and classification
The exposure category of a window or door shall be classified in accordance with Table 1. For a window or door to be included in an exposure category the test pressure for each relevant characteristics shall be attained or exceeded.
Doors that are tested and classified with a wind load greater than 1 200 shall be classified in accordance with BS EN 12207, BS EN 12208 and BS EN 12210.
NOTE The classifications given in Table 1 are those suitable for the UK selected from BS EN 12207, BS EN 12208 and BS EN 12210.
5 Sequence of test
The tests shall be performed on a single sample in the following sequence:
a) air permeability (see Clause 6);
b) watertightness (see Clause 7);
c) resistance to wind — deflection measurement at pressure P1 (see Clause 8);
d) resistance to wind — pulsating test to P2 pressure (see Clause 8);
e) resistance to wind — safety test to pressure P3 (see Clause 8).
NOTE The resistance to wind test. BS EN 12211, specifies a repeat air test.BS 6375-1 pdf download.
