They comprise both unmodified materials a
29、nd materials containing lubricants, processing aids, UV-absorbers, pigments and colorants.

30、13-1:1997 for each of the following: light transmission; impact resistance; variation of yellowness index and light transmission after ageing procedure. 5 Dimensions 5.1 General The value for the nominal sheet thickness shall be quoted by the manufacturer. 5.2 Tolerances for nominal sheet thickness
31、(Quality control test) When tested in accordance with 11.1 the values of sheet thickness obtained from crown and valley shall be the nominal thickness quotedl0 %. On the flanks the tolerance shall be the nominal thickness quoted20 %. 5.3 Tolerance for cover width (Quality control test) In addition t
32、o the requirements quoted in 5.5.4 of EN 1013-1:1997 the values of cover width shall be within an interval from 0 to +3 mm of the width stated, when measured as described in EN 1013-1:1997. 6 Visual characteristics (Quality control test) Visual or tactile examination shall reveal no evidence of any
33、hole, cracking, splitting or cluster of bubbles greater than 1 mm in diameter or inclusions that are likely to affect properties. The edges shall be straight and clean. Further requirements concerning the visual aspect of the sheets can be agreed upon between the manufacturer and the customer. 7 Lon
34、gitudinal reversion and profile retention (Type test) When the sheet is tested by the method described in 11.2 at a temperature of 80 8C for 60 min, the average percentage change in dimensions shall not exceed the following: longitudinal reversion 2 %; profile retention 3 % Manufacturers literature
35、shall give guidance where conditions of use may lead to these figures being exceeded. Page 4 EN 1013-5:2000 BSI 06-2000 8 E-modulus and tensile strength (Type test) When the sheet is tested according to ISO 527-1:1993 and ISO 527-2:1993, the E-modulus has to be at least 3000 MPa and the tensile stre
36、ngth has to be at least 60 MPa for standard PMMA. For impact modified materials the lower limits have to be declared by the manufacturer. 9 Variation of impact strength after ageing (Type test) When the sheet is tested according to method lfU in ISO 179:1993 the minimum Charpy impact strength levels
37、 acUof unnotched specimens are: Table 1 Minimal Impact strength levels MaterialUnaged samplesAged samples acUacU kJ/m2 kJ/m2 Standard$10$10 For impact modified materials the impact strength levels before and after ageing have to be declared by the manufacturer. Ageing shall be carried out in accorda
38、nce with 7.1 of EN 1013-1:1997 using a Xenon arc lamp. The duration of ageing shall be chosen so that an exposure $18 GJ/m2according to class A0 in EN 1013-1:1997 results. 10 Thermal ageing (Type test) When the sheet is exposed to dry heat for 3000 h at 80 8C by the method described in 11.3, propert
39、y levels, with respect to unexposed sheet, shall be maintained at: light transmission$90 % of its original value; change in yellowness index #10 points. 11 Test methods 11.1 Sheet thickness The sheet thickness shall be determined at any point by using a micrometer screw with hemispherical tips of 5
40、mm in diameter and with an accuracy of0,01 mm. The values as mentioned under 5.2 shall be the result of 5 measurements of which the average will be within the defined tolerance. The 5 measurements will be made at regular distances over the full sheet width. 11.2 Longitudinal reversion and profile re
41、tention 11.2.1 Principle During a given period of time, the test pieces are submitted to a determined temperature. Next, the percentage changes in length and in the pitch of corrugations are determined. 11.2.2 Apparatus air circulation oven capable of maintaining a temperature of (802) 8C; suitable
42、means of measuring test pieces to an accuracy of0,25 mm; suitable means of applying a minimum load to the test piece shall be provided as necessary to ensure that the horizontal undersides of the valleys are in contact with the flat surface immediately prior to making measurements. 11.2.3 Test piece
43、s 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 (see also Figure l): a) for pitches greater or equal to 200 mm: one pitch plus adjacent valleys on both sides; b) for pi
44、tches 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 of the sheet if neither a) and b) can be met. 11.2.4 Test procedure Carry out the test in a room maintained at a tempera
45、ture of (232) 8C and (505) % relative humidity. 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 corrugations and the distance between the marks shall be not less than 200 mm. b) Profile
46、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 than 200 mm. If the horizontal underside of the valleys are not in contact with the flat s
47、urface 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 two marks of each set of reference marks. Page 5 EN 1013-5:2000 BSI 06-2000 Place the test p
48、ieces in the air circulation oven which is at (802) 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 (802) 8C, remove the test pieces and allow to cool on a flat surface for 10 min. If the horizontal underside of
49、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 measurements. Repeat the measurement 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. 11.3 Thermal ageing 11.3.1 Principle Light transmission and yellowness index
