ISO 2602:1980, Statistical interpretation of test results Estimation of the mean Confidence interval ISO 2818:1980, Preparation of test specimens by machining ISO 8256:1990, Plastics Determination of tensile-impact strength 3 Material The sheets shall c
25、onsist substantially of polyvinyl chloride. 4 Classification Sheets shall be classified according to prEN 1013-1 for each of the following: light transmission; impact resistance; variation of yellowness index and light transmission after ageing procedure. 5 Thickness 5.1 General The value for the no
26、minal sheet thickness shall be quoted by the manufacturer. 5.2 Tolerances (quality control test) The sheets shall be measured in accordance with clause 10.1. The values of sheet thickness obtained shall be the nominal thickness quoted +0,3 mm and 20,2 mm respectively. 6 Visual characteristics (quali
27、ty control test) Both sides of the sheet shall be of regular appearance. Visual or tactile examination shall reveal no evidence of any hole, cracking, splitting or cluster of bubbles greater than 1 mm in diameter or inclusions that are likely to affect properties. The edges of the sheet shall be str
28、aight and clean. 7 Longitudinal reversion and profile retention (type test) When the sheet is tested by the method described in clause 10.2 at a temperature of 60 8C for 60 min, the average percentage change in dimensions shall not exceed the following: longitudinal reversion: 2 %; profile retention
29、: 3 %. The manufacturers literature shall give guidance where conditions of use may lead to these figures being exceeded. 8 Tensile impact strength(type test) When the sheet is tested by the method described in clause 10.3, the ratio (R) shall be greater than or equal to: for sheets having ageing cl
30、assification A11):R $ 60 %2); for sheets having ageing classification A21):R $ 40 %2); for sheets having ageing classification A31):R $ 30 %2). 9 Thermal ageing(type test) When the sheet is exposed to dry heat for 3000 h at 65 8C by the method described in clause 10.4, property levels, with respect
31、to unexposed sheet, shall be maintained at: light transmission:$ 85 % of initial value; change in yellowness index: # 20 points. Page 4 EN 1013-3:1997 BSI 1998 10 Test methods 10.1 Sheet thickness 10.1.1 Apparatus The sheet thickness shall be determine at any point using a micrometer screw with hemi
32、spherical anvils of 5 mm in diameter and with an accuracy of +0,01 mm. 10.1.2 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 end. First and last measurements ar
33、e to be within 25 mm of the sheet edges. 10.2 Longitudinal reversion and profile retention 10.2.1 Principle An elevated temperature test is conducted on test pieces, and percentage changes in length and in the pitch of corrugations are determined. 10.2.2 Apparatus air circulation oven, capable of ma
34、intaining a temperature of (602) 8C; suitable means of measuring test pieces, to an accuracy of 0,25 mm. NOTEAn example of a suitable measuring device is shown in Figure 1. Suitable means of applying a minimum load to the test pieces shall be provided as necessary to ensure that the horizontal under
35、sides of the valleys are in contact with the flat surface immediately prior to making measurements. 10.2.3 Test pieces Five rectangular test pieces are required, which shall be not less than 250 mm in length. The width of test pieces shall be such that one of the following conditions is satisfied (s
36、ee also Figure 2): a) for profiles greater or equal to 200 mm: one pitch plus adjacent valleys on both sides; b) for pitches less than 200 mm: the minimum number of pitches which gives a distance greater or equal to 200 mm between outer crowns with adjacent valleys on both sides; c) complete width o
37、f the sheet if neither a) nor b) can be met. 10.2.4 Test procedure Carry out the test in a room maintained at a temperature of (232) 8C. Scribe two pairs of reference marks on each test piece as follows: a) longitudinal reversion: the line joining the two marks shall be parallel to the axis of the c
38、orrugations and the distance between the marks shall be not less than 200 mm; b) profile retention: the marks shall be on the crown of two corrugations. The line joining the two marks shall be at right angles to the direction of the corrugations and the distance between the marks shall be not less t
39、han 200 mm. If the horizontal undersides of the valleys are not in contact with the flat surface, apply load(s) to the sheet just sufficient to obtain contact between the horizontal undersides of the valleys and the flat surface before conducting any measurements. Measure the distances between the t
40、wo marks of each set of reference marks. Place the test pieces in the air circulation oven, which is at (602) 8C, in such a way that they are under no stress. After a period of 60 min, which shall commence when the temperature of the oven regains (602) 8C, remove the test pieces and allow to cool on
41、 a flat surface for 10 min. If the horizontal undersides of the valleys are not in contact with the flat surface apply load/s to the sheet just sufficient to obtain contact between the horizontal undersides of the valleys and the flat surface before conducting repeat measurements. Repeat the measure
42、ment of the distances between the marks on each test piece and calculate the individual and average percentage changes in length and in the pitch of the corrugations. 10.3 Change in tensile impact strength 10.3.1 Principle The energy required to fracture is determined by the kinetic energy extracted
43、 from a pendulum in the process of breaking the test pieces. Tests are conducted on unaged and aged test pieces and the ratio of tensile impact strengths is determined using statistical techniques. 10.3.2 Apparatus The apparatus is as described in clause 5 of ISO 8256:1990 for method A using un-notc
44、hed test pieces. Page 5 EN 1013-3:1997 BSI 1998 10.3.3 Test pieces Test pieces from unaged and aged material shall be: a) that shown as Type 5 in ISO 8256:1990 when the cross-section of the sheet allows a flat specimen of (232) mm width to be obtained; b) that shown as Type 3 in ISO 8256:1990 when t
45、he cross-section of the sheet does not permit specimens as given in a) to be taken but allows a flat specimen of (150,5) mm width to be obtained. Where the cross-section of the sheet does not readily allow a flat specimen of Type 5 according to a) or Type 3 according to b) to be taken, the following
46、 procedure shall be executed. The test pieces shall be flattened by heating in a hot air oven at (1205) 8C for between 2 and 5 min. Immediately after removal from the oven the test pieces shall be placed in a suitable press. In these circumstances the shape of the test piece shall be as given in a).
47、 A minimum of 20 test pieces shall be used, at least 10 test pieces each representing unaged and aged material. Dimensions of sheets for exposure in the xenon arc apparatus shall be greater than those shown above. If it is necessary to flatten sheets by heating at (1205) 8C, then this shall be carri
48、ed out before the material is exposed in the xenon arc apparatus. The length dimension shall be parallel to the direction of the profile and this orientation shall be preserved if sheets are flattened. Ageing shall be carried out in accordance with clause 7.1 of EN 1013-1:1997. The final shape of ea
49、ch test piece shall be obtained by machining in accordance with ISO 2818:1980. The tool rotation speed for high speed rotary machines may be greater than that specified. The unaged and aged test pieces shall be the same shape and prepared by the same method. 10.3.4 Test procedure 10.3.4.1 Each test piece shall be visually examined to ensure that it is free from any defects. 10.3.4.2 Each test piece shall be tested in accordance with ISO 8256:1990 method A and the tensile impact strength determined
