Unless otherwise specified, each specimen shall be tested in the conditioning atmosphere and at the conditioning temperature, or the tests shall commence within 3 min of removal of each test specimen from the
40、conditioning atmosphere. Where testing at an elevated temperature is required in one of the specification sheets of IEC 60893-3, test specimens shall be conditioned for 1 h at that elevated temperature immediately before testing. 4 Dimensions 4.1 Thickness 4.1.1 General Any method which enables the
41、thickness of the laminated sheet to be measured at an appropriate number of points may be used, provided that the equipment used and the method of measurement are capable of a precision of 0,01 mm or better.

42、e suitable and shall be used in cases of dispute. 4.1.2 Test apparatus for reference method In case of dispute, an external screw type micrometer according ISO 3611 having faces with diameters between 6 mm and 8 mm shall be used. 4.1.3 Procedure for reference method Measure the thickness of the rigi
43、d laminated sheet as delivered to the nearest 0,01 mm at eight points, two along each edge but not less than 20 mm from the edge. 4.1.4 Results Report the maximum and minimum measured values and the arithmetic mean of all measured values in mm. 4.2 Flatness 4.2.1 General This test is applicable to a
44、ll sheets having a thickness of 3 mm or greater. 4.2.2 Test specimens The test specimen shall be the whole sheet or panel under test in the as received condition. 4.2.3 Test method When any sheet of nominal thickness 3,0 mm or more is placed without restraint, concave side up, on a flat surface, the
45、 departure at any point of the upper surface of the sheet from a light, straight edge 1 000 mm or 500 mm in length, laid in any direction upon it, shall not exceed the value given in the relevant sheet of IEC 60893-3 appropriate to the material, its thickness and length of straight edge. The mass of
46、 the 1 000 mm straight edge shall not exceed 800 g, and the mass of the 500 mm straight edge shall not exceed 400 g. 4.2.4 Results Report the maximum measured deviation from flatness in mm. NOTE In cases where the sheet deviates from flatness in two directions, is saddle-shaped, measure both deviati
47、ons and report the highest. 5 Mechanical tests 5.1 Flexural strength 5.1.1 General The flexural strength is defined as the flexural stress at rupture. It shall be determined by the method specified in ISO 178. 5.1.2 Test specimens Cut the test specimens from the sheet to be tested with their major a
48、xes parallel to the sides of the sheet. Test five test specimens in each direction, except for types with fibres aligned mainly in the same direction. In such cases, cut five specimens only, with their long axis parallel to the direction of the fibres. Page 6 EN 608932:2004 -398063002:CEI 2 71 If th
49、e nominal thickness of the sheet to be tested is more than 10 mm (20 mm in the case of types PF WV), reduce the thickness of the test specimens to 10 mm (20 mm in the case of PF WV). When it is necessary to reduce the thickness of a test specimen, machine it, leaving one face of the sheet intact. In such cases, test specimens shal
