3 Terms and definitions
For the purposes of this document the terms and definitions given in EN 1363-1:1999, EN 1363-2:1999. EN 1366-4:2006+A1:2010, EN 13501-1:2007+A1:2009, EN 13501-2:2007+A1:2009 and EN ISO 13943:2010, and the
following apply:
fabric seal
seal comprised of a woven fabric, usually glass cloth or similar. which may be used in a combination with other material, such as metal facings, etc. to provide a composite seal
3,2
foam seal
seal made from a one, two or three component expanding foam (expands during apphcation), applied in-situ
3.3
joint depth
overall distance between the exposed and unexposed faces across the thickness of the separating element
Note Ito entry: See Figure 1.
3.4
joint face framing
additional substrate incorporated between the supporting construction and the joint seal
3.7
mortar seal
seal comprising a cementitious or gypsum based compound together with other filler materials, usually mixed on site with water to achieve the required workability
3.8
movement joint
joint between adjacent building elements or within a building element designed to accommodate a degree of movement greater than ± 7,5% (such as deflection, thermal movement or seismic)
3.9
non-movement joint
joint between adjacent building elements or within a building element not designed to accommodate movement greater than ± 7.5% (such as those designed to accommodate construction tolerances or irregularities of fit)
3.10
seal depth
shortest distance between the exposed and unexposed surfaces of the seal
Note 1 to entry: See Figure 1.
3.11
seal width
width of the seal In the non-installed condition (for uncompressed solid seals, see Figure 1, detail A) or the width of the installed seal where it is equal to or different from the joint width (e.g. overlap) (see Figure 1, details B and C)
3.12
sealant seal
seal formed from materials such as acrytics, silicone, oil-based products (mastic, putty), foamed in-situ, normally in conjunction with a backing material and inserted into the joint
3.13
strip seal
pro-formed seal normally inserted into the joint and held in place by friction or by means of an adhesive
Note I to entry: Strip seals may also include impregnated or multi component (composite, laminated) seals such as a combination of foam tape with strips of intumescent material.
3.14
surface mounted strip
surface mounted seal applied over the joint to completely cover and overlap the joint and usually mechanically fixed to the surface of the building element
4 Extended application principles
4.1 General
Due to the diverse nature of materials and constructions used to seal linear joints or construction joints in fire resistant separating elements, it has 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 type 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 1366-4);
— 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 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.BS EN 15882-4-2012 pdf download.
