BS EN 13984-2013 pdf download.Flexible sheets for waterproofing Plastic and rubber vapour control layers Definitions and characteristics.
5.1 General
5.1.1 Where a tolerance is limited by this European Standard, it does not have to be declared by the manufacturer.
5.1.2 When tested for purposes other than initial type testing or factory production control, the tests to determine product characteristics indicated in this European Standard shall be started within one month of delivery from the manufacturer.
5.2 Visible defects
The product shall be free of visible defects as determined in accordance with EN 1850-2.
5.3 Dimensions and tolerances
The length, width and straightness shall be determined in accordance with EN 1848-2. The length and width shall lie within the declared tolerance of the manufacturer’s declared value (MDV). The maximum deviation from straightness shall not exceed 75 mm per 10 m length or in proportion for other lengths (e.g. 37.5 mm per 5 m length).
5.4 Thickness and mass per unit area
The thickness and mass per unit area shall be determined in accordance with EN 1849-2.
Where a product is specified by mass per unit area, the mass shall lie within the declared tolerance of the manufacturer’s declared value. Where the dimensions of any profile are comparable to the area to be measured, a larger sample area shall be used and the deviation from the test method noted.
Where a product is specified by thickness, the minimum thickness shall lie within the declared tolerance of the manufacturer’s declared value. No single measurement shall lie outside the declared tolerance of the manufacturer’s declared value.
5.5 Water tightness
Types A and V vapour control sheets shall be watertight as determined by EN 1928:2000, Method A, with a
pressure of 2 kPa.
5.6 Resistance to impact
Where required, the resistance to impact shall be determined In accordance with EN 12691 and the result shall be greater than or equal to the manufacturer’s lImiting value.
5.8 Resistance to tearing (nail shank)
For unreinforced sheets, the tear resistance (nail shank) shall be determined in accordance with EN 12310-1 and shall be greater than or equal to the manufacturer’s limiting value.
For reinforced sheets, the tear resistance (nail shank) shall be determined in accordance with Annex B of EN 13859-1:2010 and shall be greater than or equal to the manufacturers limiting value.
5.9 Joint strength
Where required the joint strength shall be determined in accordance with EN 12317-2 and shall be greater
than or equal to the manufacturers limiting value,
5.10 Water vapour transmission properties
The water vapour resistance shall be determined in accordance with EN 1931 and shall lie within the declared tolerance of the manufacturers declared value.
5.11 Tensile properties
The tensile properties of unreinforced sheets shall be determined in accordance with EN 12311-2 and shall be greater than or equal to the manufacturer’s limiting value for the longitudinal and transverse directions of the sheet.
The tensile properties of reinforced sheets shall be determined in accordance with Annex A of EN 13859-1:2010 and shall be greater than or equal to the manufacturer’s limiting value for the longitudinal and transverse directions of the sheet.
5.12 Reaction to fire
Where required, the product shall be tested and classified in accordance with EN 13501-1 :2007+A1 :2009, Table 1. According to EN ISO 11925-2. the test is required to be undertaken on the exposed surface of the delivered flexible sheet (surface or edge exposure) free hanging without any substrate in one direction only, and the reinforcement has to be stated by the manufacturer as “organic or “inorganic.
a) Test results from EN ISO 11925-2 for a given product shall apply to all colours (including black, white).
b) Test results from EN ISO 11925-2 for a given product without an inner layer (homogenous) shall apply to a comparable product with an additional organic inner layer (lower than 150 g/m2) or any additional inorganic layer.BS EN 13984-2013 pdf download.
