BS EN 15836-2-2010 pdf download.Plastics Plasticized poly(vinyl chloride) (PVC-P) membranes for ing round swimming pools Part 2: Reinforced membranes of nominal thickness equal to or greater than 1 ,5 mm.
3.1.1
reinforced membrane
sheet made of plasticized poly(vinyl chloride) sheets and a polyester reinforcement
NOTE 1 These membranes can be manufactured e.g. by extrusion, calendenng or cast spreading,
NOTE 2 The membrane is waterpoof and gas-pervious, package in roll form and intended to be implemented in situ.
3.1.2
inground swimming pool
permanent installation containing treated water for water activities totally or partially realized under the ground level with a water depth  0,85 m or a water volume  8 m3
3.2 Symbols
E thickness of the membrane declared by the manufacturer, in millimetres
l width declared by the manufacturer, in metres or millimetres
L length of the roll declared by the manufacturer, in metres
mass per unit area declared by the manufacturer, in grams per square metre
3.3 Abbreviations
CaCO3 calcium carbonate
PVC-P plasticized poly(vinyl chloride)
4 Sampling and conditioning
4.1 Sampling
The test pieces shall be taken only from rolls of unused membranes.
4.2 Conditioning of test pieces
Unless otherwise specified by the applicable test method, the test pieces used for the determination of the characteristics shall be conditioned before testing for at least 4 h in standard atmosphere 23/50 [(23 ± 2) °C. (50 ± 10) % HR] according to EN ISO 291.
5.2 Heavy metals and other dangerous substances
The PVC-P membranes should conform to all national and international regulations in force.
The PVC-P membranes shall consist of materials that are not substances classified as carcinogen category 1 or carcinogen category 2, mutagen category 1 or mutagen category 2, toxic to reproduction category 1 or toxic to reproduction category 2 (see Directive 761769/EEC [1J).
The total concentration of lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium [Cr(Vl)J and arsenic (As) shall not exceed 100 mg/kg.
NOTE This requirement is based on the concentration levels of heavy metals present in packaging as defined in Directive 94/621EC. Artic’e 11 [21.
For the determination of the total concentration of Pb, Cd, Hg, Cr(Vl) and As, the method given In Annex A shall be used.
5.3 Environmental aspects
The PVC-P compounds are recyclable materials that can be treated in a material recovery process intended to save resources while minimising harmful emissions into air, water and soil as well as their impacts on human health.
NOTE A scheme for the characterisation of plastics waste is given in EN 15347 (31 and data for the characterisahon of PVC recyclates are given in EN 15346 [4J.
6 Visual characteristics
6.1 Appearance
Visible defects in the reinforced membrane shall be determined using the method specified in EN 1850-2.
A visual inspection shall be made on a minimum area of the reinforced membrane that is 2 m long and as wide as the membrane itself. The inspection shall be performed on samples of both sides of the membrane taken at random from a roll laid down, without tension, on a flat, opaque surface.
The reinforced membrane shall have no defects visible to the naked eye, such as bubbles, blisters, coloured streaks, pinholes, mottles, folds or ripples. However air inclusion and mottles cannot be completely avoided in PVC-P sheet.
The appearance shall be uniform, as even as that of the reference test piece, irrespective of the area examined. The surface condition (smooth or embossed) and the colour reflection shall be in conformance with those of the reference test piece.
Non-printed reinforced membranes shall have an even surface finish.
In the case of a printed reinforced membrane, the imprint shall be even with no smudging. No ink shall be transferred to the non-printed side.
An embossed reinforced membrane shall have a regular appearance with an even pattern.
The pigments shall be homogenously and evenly distributed throughout the material. Slight differences in colour, related to composition and manufacture shall generally be permissible.
The rolls of reinforced membranes shall be suitably arid sufficiently tight.
The result of the visual examination shall be expressed as “appearance conform” or “appearance non-
conform”. In the latter case, the defects noted shall be listed.
6.2 Colour (plain coloured membranes)
The colour of the unused (new) membrane, as delivered, shall be the same as that of the reference sample as agreed between the supplier and the customer.
The contrast or visual differences between the unused membrane and the reference sample shall be assessed in accordance with EN 20105-A02.
NOTE The trichromatic coordinates L”, u and h determined according to ISO 7724-1 [5], ISO 7724-2 [6] and ISO 7724-3 [7J can be used to assess the colour of the membrane, as well as any differences in colour between the membrane and the reference sample. However, pemiissible limits cannot be defined in this document
