45、assess compliance are not given in 5.3 - 5.12 (inclusive). 5.2 Test specimens, conditioning and order of testing For the tests given in 5.3 - 5.6, use a sample of acrylic sheet of adequate size and of the same type, quality, thickness and, when relevant, colour and, if possible, from the same batch
46、as that used in the production of the bath specimens used in the other tests. Unless otherwise stated, condition all acrylic sheet specimens and baths for at least 16 h at a temperature of 23 2 C and a relative humidity of 50 5 %, and conduct the tests under these conditions. Use fresh acrylic sheet
47、 specimens for each of the tests given in 5.3 - 5.6. Carry out the tests given in 5.7 - 5.12, in the sequence 5.8 - 5.9 - 5.10 - 5.11 - 5.12 - 5.7, on each bath in the sample.

Measure, to the nearest 0,5 mm, the distance between each pair of gauge marks on the same line. Hang the specimens in the oven for 1 h, then remove them, allow them to cool to room temperature while suspended freely and recondition them as in 5.2. Then proceed as follows: a) examine the specimens visually for the presence of blisters or bubbles or both; a
