EN 1013-1:1997, Light transmitting profiled plastic sheeting for single skin roofing Part 1: General requirements and test methods. 3 Materials 3.1 The sheet shall be composed of a thermo-setting polyester resin system reinforced with glass fibre. 3.2 Th
26、e system shall include curing agents, catalysts and light stabilizers. NOTEAdditives such as fillers, fire retardent and colouring matter may be included. 3.3 To retard surface erosion and exposure of glass fibres, surface protection on exposed weather surfaces is required. The manufacturer shall st
27、ate the method of protection used and the side which is protected. NOTEA surface gel coat will normally provide such protection. This consists of a polyester resin incorporating a high percentage of UV light stabilizers. The gel coat is applied to the sheet during manufacture to provide a durable re
28、sin-rich surface. When sheets are to be installed in zones where excessively harsh environmental conditions exist and a more durable surface protection may be needed, the use of a polyvinyl fluoride (PVF) surface film should be considered. Other forms of surface protection include adherable polythyl
29、ene terephthalate films. 4 Classification 4.1 General Sheets are graded into four categories. These grades are based on minimum thickness and minimum weight of glass fibre per square metre. 4.2 Glass fibres 4.2.1 The minimum weight of glass fibres shall not be less than 25 % by weight of the sheet.
30、4.2.2 The weight of glass fibres shall be determined by the test method detailed in clause 11.1. NOTEWhen the density of the resin can be readily established, the glass content by laminate density detailed in annex A may be used as a quality control test. 4.2.3 The minimum weight of glass fibres per
31、 m2shall be based on the extended sheet area. The minimum weight for each category shall not be less than the values specified in Table 1. Table 1 Glass fibre content CategoryMinimum weight of glass fibres in g/m2 based on extended area of sheet 1270 2350 3450 45801) 1)The minimum weight of glass fi
32、bres in category 4 sheets shall be quoted by the manufacturer. It shall not be less than 580 g/m2. 4.3 Sheet thickness The individual and mean thickness of the sheet when measured in accordance with clause 11.2 shall comply to the values given in Table 2.

The mean thickness shall not vary by more than 15 % of this stat
35、ed value. 5 Visual characteristics 5.1 Surface faults Visual or tactile examination shall not reveal the following faults: any hole, pin hole, dent or projection; any cracking or splitting; any defects such as resin ribs, glass folds, or glass knots, exceeding 5 mm in size. 5.2 Faults revealed by tr
36、ansparency Examination by transparency to daylight shall not reveal the following fault: any air bubbles greater than 1 mm diameter outside the zone of the overlap. 5.3 Local geometrical defects at edges The edges of the sheet shall be straight and clean. 6 Barcol hardness When the sheet is tested i
37、n accordance with clause 11.3, the Barcol hardness shall not increase by more than 10 % of its initial value. NOTEThis test is only to check the correct cure of the resin during production. 7 Determination of tensile property When the sheet is tested in accordance with the test procedure given in EN
38、 63, the breaking stress shall not be less than 150 N/mm2. NOTEThe figure 150 N/mm2is not representative of the resistance of profiled sheets but only for the bonding between the resin and the glass fibres. 8 Presence of protective coatings The presence of protective coatings shall be confirmed in a
39、ccordance with the acid immersion test described in clause 11.4. The immersion times and descriptive effects of immersions are detailed in Table 3. These tests only confirm the presence of surface coatings. The durability of such coatings shall be established according to subclause 5.4, variation of
40、 yellowness index and light transmission after ageing procedure of EN 1013-1. 9 Adhesion of surface coatings The adhesion of surface coatings, determined in accordance with the adhesion peel test detailed in clause 11.5, shall be considered satisfactory when the film cannot be pried up or peeled mor
41、e than 3 mm. 10 Classification of tests Type tests are the following: measurement of glass fibre contents by burning; determination of tensile properties. Routine tests are carried out to control the following: glass fibre contents by laminate density; thickness; visual characteristics; Barcol hardn
42、ess; adhesion of surface coating; acid immersion test. 11 Test methods 11.1 Determination of glass content by burning off resin 11.1.1 General The apparatus, conditioning of test samples and test procedures shall be in accordance with EN 60. 11.1.2 Test specimens Test 4 specimens, each approximately
43、 100 g, to be taken from across the full width of the sheet. 11.1.3 Method of measurement The extended width of the specimen shall be measured by an inelastic adhesive tape applied over the corrugation or ribs over the full width of the specimen. Remove the tape to measure the extended width. Page 5
44、 EN 1013-2:1998 BSI 03-1999 11.1.4 Procedure Note the extended width and length of each specimen; weigh each specimen; ash the specimen; ensure all carbon black residue is oxidized; wash the residue in water; filter through a sieve to retain only glass fibres; repeat washing procedure three times; d
45、rain off excess water and allow residue to dry for 2 h at (1202) 8C; re-weigh glass residue. 11.1.5 Expression of results Weight of glass fibre per m2of extended sheet area; percentage of glass fibre by weight of the original specimen. NOTEAfter measuring the size and weight of the specimens they ma
46、y be cut into several pieces for testing. When ashing specimens toxic fumes may be evolved. Suitable safety precautions are to be taken. 11.2 Measurement of sheet thickness 11.2.1 Apparatus The sheet thickness shall be determined at any point using a micrometer screw with hemispherical anvils of 5 m
47、m in diameter and with an accuracy of 0,01 mm. 11.2.2 Method of measurement Sheet thickness shall be checked by nine measurements taken at random in the crowns, valleys and flanks across the total sheet width at a distance of 20 mm from the one end. First and last measurements to be within 25 mm of
48、the sheet edges. 11.2.3 Expression of results Record the nine values and calculate the mean of the nine recorded values to the nearest 0,01 mm. 11.3 Measurement of Barcol hardness 11.3.1 General The apparatus, calibration, conditioning of test specimens and test procedures shall be in accordance wit
