21、n necessary to separate the extended application principles into generic seal types. Permitted variations may be used alone or in combination, unless stated otherwise. Principles common to all generic seal types are given in 4.2. Principles and guidance relating to each specific generic joint type a

22、re given in Annex A of this European Standard. Variables for each seal type which require consideration, are included in this report. These are as follows: separating element; joint width/seal width; joint depth/seal depth; seal position in relation to the exposed face; orientation (see EN 1366-4);

23、whether the joint is a movement or non-movement joint. Each sub-clause gives the possible variation and the rule relating to the variation. The following rules are considered applicable to joint assemblies tested either with or without induced movement. 4.2 Principles common to all generic seal type
