3.1 Equipment only
3.1.: Pressure test: The measuring force is 20N, and the relative indication error should be less than 115. The test machine should have a device to display the deformation caused by the music.
3.1.2 Electric drum drying oven,
3.1.3 Dryer.
3.1.4 Balance: weigh 2kg-3.1 g, 3.1.5 Steel ruler with a graduation value of 1mm.
3.1.6 Emulsified oil with a solid content of 50% (or petroleum oil with a softening point of 40-75). 1mm thick source oil. Small paint is used to scrape the melted paint. Use auxiliary equipment such as a scratching crucible, 3.2 Test
3.2.1 Randomly hang the product. Take one at 5m around the two diagonal edges and the center of each flat plate (or block) in any pair of straight lines, and make a square of about 10mm×1ml thick for the product thickness test piece, and the industry plate tube Fill the test piece into a square of 100mm×1cm, as thick as possible, but the thickness of the test piece shall not be less than 25mm. When the test piece of this size cannot be made, it can be replaced by a commercially available electrode of the same type and process. 3.2.2 The surface of the test piece shall be flat and there shall be no cracks. 3.3 Test procedure
3-3.1 Within the first ten days of the test piece, the external resistance shall be raised to 393K±K (1101.5) according to the fixed head dry rate of GB/T 5486.82.5.2. Then move the test piece down to the blasting device until it is difficult to resist. 3.3.2 Measure the length and width of the specimen at the root edge mnl, and measure the thickness of the specimen at the middle of the two corresponding surfaces. The result of the measurement shall be the average value of the two measurements and accurate to 1m.3.3.3 Before the test, use a brush or knife to evenly remove the emulsified asphalt or molten asphalt on the upper and lower surfaces of the specimen. The pores must be flat. Then cover the surface with a piece of paper of uniform size of 1mmx10mm cut in advance. Dry in a dryer for at least 21 hours. 5486.2—2301
3.3.4 Place the specimen on the compression test machine or on the plate so that the center of the card test machine bearing plate coincides with the center of the test piece. 3.3.5 Start the test machine and when the upper and lower parts are close to the specimen, adjust the seat and make sure that the pressure surface and the pressure plate are in uniform contact. 3.3.6 Separate the specimen and the pressure test machine at a speed of about 10mm/s. When the specimen is broken or damaged, record the pressure pain and deformation at the same time. When the test piece is not damaged at a deformation of 5%, the number of deformations of the specimen under pressure is recorded as P, and the probability of failure is 10N.3.4 Calculation and evaluation of the results
3.4.1 The compressive strength of each specimen shall be calculated according to the actual (1.01M\a.aw

4.2 Test piece
4.2.1 Randomly take three samples, each of which has a length of 24) mm~-3 cm, a width of 75 mm~-15 cm, and a thickness of the product thickness. The pipe and the curved plate should be cut into a test piece with the same length, width, and thickness as possible, but the thickness shall not be less than mm. When the above test pieces are not made, the flat plate made by the same process can be used instead: 4.2.2 The test piece should not be subject to the deadline, and there should be no level difference: 4.3 Test steps

4.33 Before the test, the foam end insulation products should be evenly coated with emulsified paint at the supporting points and decorative points, and then the paint should be pre-painted. A paper mold with a width of m should be covered on the coating member and placed in a dryer for at least 24 minutes. 4.3.4 The spacing between the two support wheels is n1. If the thickness of the specimen is greater than mm, the spacing between the two support wheels should be increased to at least 3 mm. 4.3. The test piece should be placed symmetrically on the support wheels. The speed should be increased so that the descending speed of the pressure wheel is about 10 mm/min. 4.3.E should be increased until the test piece breaks. Record the maximum failure load of the specimen, accurate to [N]. 4.4.1 The flexural strength of each specimen shall be calculated according to (2) or (3) with an accuracy of 0.01Pa3PI. In the formula, R is the tensile strength of the specimen, Ma
