The time at which the first crack appears shall be reported. 5 Test methods 5.1 Determination of tensile strength 5.1.1 The test piece
37、s shall be as described in ISO 527, Type 1 B. They shall be cut so that their length is parallel to extrusion direction. The thickness of the test piece shall be that of the sheet from which it is cut and the width and the thickness shall be measured on the parallel portion of the test piece by mean
38、s of a micrometer to the nearest 0,025 mm. 5.1.2 The test shall be carried out at a temperature of (23 ? 2)C and the test pieces shall be conditioned to this temperature for at least two days before testing. 5.1.3 The speed of testing shall be (5 ? 1) mm/min (speed B). 5.1.4 The mean of three determ
39、inations shall be recorded as the tensile strength of the material but if a test piece breaks in the grips the result shall be disregarded and a further determination made. The tensile strength shall be determined according to ISO 527. 5.2 Determination of thermal stability Hang two sheets 300 mm sq
40、uare, taken from the impact modified extruded acrylic sheet, in a circulating oven at (165 ? 5)C for 20 minutes when this nominal temperature is reached. Remove the sheets from the oven, allow them to cool to room temperature while hanging vertically and visually examine them for the presence of bli
41、sters. If defects are present, repeat the test on new samples with pre-conditioning at (80 ? 2)C for 16h. EN 13558:2003 (E) 7 5.3 Determination of colour fastness to hot water 5.3.1 Cut a test piece 100 mm x 25 mm from the impact modified extruded acrylic sheet and fix in a suitable carrier. Immerse
42、 the test piece in a water bath maintained at (60 ? 2)C for 30 min, remove and allow to drain and dry out in air for 30 min. 5.3.2 Repeat the cycle 100 times without interruption. 5.3.3 Allow 48 h for the test piece to dry out before it is compared with a sample of the sheet from which it was cut. 5

Each aqueous solution shall be prepare
44、d immediately before application. The reagents shall be made up and applied at (23 ? 5) C.

45、silicate watch glasses 40 mm nominal diameter 5.4.2.2 Pipettes 5.4.2.3 Cleaning device The cleaning device is shown in figure 1. It comprises a synthetic flexible open cell foam disc of 75 mm diameter and 15 mm thick. Use any rotating device applying a mass of (1000 ? 50)g which losely fits with the
46、 device. The lateral cleaning force shall only be that exerted by the mass of the cleaning device; this can be effected by a floating action between the drive shaft and the disc. EN 13558:2003 (E) 8 5.4.2.4 Test specimens Specimens shall measure (100 ? 5) mm x (100 ? 5) mm. 5.4.3 Procedure Use a sep
47、arate test specimen for each reagent test. Clean the test area thoroughly with hot soapy water, rinse and dry with a clean soft cloth. On each test specimen deposit a drop of the test solution. Cover the drop thus formed with a watch glass concave downwards. The drop size shall be determined in orde
48、r to be completely covered by the watch glass. Allow to act for a time of (120 ? 5) min, at a temperature of (23 ? 5)C with the test areas protected from the affects of sunlight. Thoroughly rinse the test specimen with demineralized water and check for adverse changes in appearance by visual examina
49、tion. If deterioration exists, dip the foam disc of the cleaning device into demineralized water and place it on the surface to be cleaned. Rotate the device at 60 rotations per minute. Clean for 30 revolutions. Rinse with demineralized water and visually examine the test area. If deterioration persists repeat the cleaning process with an abrasive agent added to demineralized water. This abrasive agent is defined as follows : alumina used for surface polishing, with particle size comprised
