19、odology for the preparation of extended application reports for linear joint sealing systems tested in accordance with EN 1366-4. The field of the extended application reports is additional to the direct field of application given in EN 1366-4. It may be applied to or based on a single test, or a nu
20、mber of tests, which provide the relevant information for the formulation of an extended application. Mechanical metal seals are not part of the scope of this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are i

35、 been 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 ty
36、pe are 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-
37、4); 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
38、types 4.2.1 General The rules given in the following sub-clauses are applicable to all generic linear joint seal types incorporated within Annex A, unless stated otherwise in the specific section.

The standard supporting construction shall be in accordance with the provisions given in EN 1363-1, and subject to the following: 1) The wall shall be restrained only on the top and bottom
42、edge. 2) The number and thickness of the gypsum board(s) shall be as given in Table 3. 3) A construction including insulation shall be used. The insulation material shall be mineral wool with a classification of A1 or A2 according to EN 13501-1. The density of the insulation shall be (45 15) kg/m3fo
43、r a desired fire resistance up to and including 60 minutes, and (100 15) kg/m3for a fire resistance of more than 60 minutes. The thickness shall be such that the remaining gap between the board and the insulation is a maximum of 15 mm. 4) Steel studs of varying widths may be used to fit the flexible
