5.4.1 The method is to compare the core material with the low-consumption light material of the market for regular effectiveness testing, when the test is successful! The average constant of the total sample volume is calculated by using the standard dielectric constant K·Li1emrrk of the dielectric band microstructure of the object. 5.4.2 Test apparatus is in accordance with D59. 5.4.3 Test sample preparation technology G5597: Place the red stone material in a uniform volume ratio of about 1 piece and then press the machine to form the product. 5.4.4 Test Calculation of the results

E.3 The requirements for the selection of the test, shape, size and number will contain the provisions of the test fee method. E.4 If there is a sample in the test, the standard is in line with the table in this standard? In reality, the gold material is considered qualified. Even if the test cycle does not meet the standard of the station chief wave 2, the test is made of the same village material. The test is delayed for 1 selection project. If the total learning injury is unqualified, the material is not qualified from the enterprise 7 signs, packaging, storage and transportation. The product name, product model, and the manufacturer H plan to study the color table will be the gold powder table. The bottle is 1.3! The storage must be stored in a clean and ventilated, dry military room. The transportation method of this product can be used to transport the product. The transportation method is added to the description. This standard is issued by the Shandong Provincial Academy of Sciences. The Shandong Provincial Academy of Sciences has issued a list of chemical products for free production of mechanical and electronic industry secrets, and the research and development of the standard is responsible for the drafting.
