Except for the less than 0 in the figure, cut the strips with a length of 50 and a width of 100 in the direction of the strip,
H.3 Test procedure
B.3, 1 Set the temperature to a certain level (particularly ±2 °C), wait for the temperature to be determined, put the test pieces in the test chamber, and require that the samples have no discoloration. At the same time, conduct heat resistance test B.3.2 After 211, take out the test pieces from the constant temperature box, and observe whether the surface of the test pieces has cracks, stickiness, etc. 4 Test results
If the surfaces of two samples show cracks, stickiness, etc., they are qualified. If one or more samples show cracks, stickiness, etc., then add 2 more tests. The added test refers to the phenomenon of abnormal banding such as the appearance of the test piece or the engine, which is not a standard.
C.1 Test principle
Normative appendix)
Explosion-proof water-resistant test method for polyester fabric MT956-2005
Test the conditions under a certain environment, and then perform a bending test in a low-temperature box for a certain time to check the damage of the test.
C.2 Package inspection
.2.1 Low-temperature box: The temperature range is 5~1%℃ and the humidity display is set. The low-temperature box should have a bending room of equal size to the size of the test knife and the hand change, so that the operation of the test can be carried out in a low temperature control. The temperature in the temperature pen is within the range of 32. (.2.2 or appointment board: used to place all the sincerity, its size is about (151×5) m, the number of pieces is: C.2.3 two widths 3 to, 1 lead and place in the temperature environment of the sample, take the other 2 samples in the low temperature box in the room, put them on the face of the set, and change them to ensure the safety of the operator. (3 Samples and their preparation
Cut the edge of the H polyester cloth at least um, with a warp and weft spacing of 10 cm and a width of 2 mm.
Center, 4 Test procedure
C.4., reduce the low source temperature to: -2 + 31, and carry out the following procedures after the temperature is realized. C.4.2 Place the test glass in a low temperature box with enough space between the test glass and the test sample to allow air to circulate during the test. Put the glass with the test sample in a low-temperature box as a belt and store the cover in a low-temperature box. C.4.3 Under the above temperature conditions, take one piece of glass from the two ends of the test sample at a time in the low-temperature box, then fold the sample 180° and use a folding machine to check whether the sample has any abnormal phenomena such as damage or cracks. C.5 Test results: If the surface of the total sample is analyzed by element, and there is no abnormal phenomenon such as damage or deformation, it is qualified. If one or more test samples show abnormal phenomena such as damage or deformation, retest. If one or more test samples show abnormal phenomena such as damage or deformation, it is unqualified.
