This standard is a revision of CB/410—83:
The provisions on sampling method have been deleted. Other matters are editorial in nature. This standard is proposed by China Nonferrous Metals Industry Association and is under the jurisdiction of China Nonferrous Metals Standardization Technology Committee at the standard publication meeting. This standard is issued by Northeast Light Alloy Co., Ltd., and the main author of this standard is Han Shu. The National Technical Committee for Nonferrous Metals Standardization is responsible for the interpretation. The version of the standard replaced by this standard is: GB/T4107-1983. CE/T 4107—2004 1 Scope Determination of bulk density of magnesium powder Scott disk method This standard specifies the test method for determining bulk density of magnesium powder by Scott and Scott disk method. This standard is suitable for determining full buckets of magnesium powder that can pass through a 2500m sieve. 2 Normative referenced documents

3 Principle
Let the powder wine expire in the world hold the series of inclined plates in the design, and put it into the measuring cup with the unloaded area in the shape of a bleached cloth, and then measure its mass to form the mother loose density
4 Sampling
Sampling is carried out according to the method specified in GB5149.1, 5 Equipment and receiver
5.1 Special design of materials: 1 Unpack the following parts: 5.1.1 Funnel: with a hole through 2CC ground key calibration cross net 5.1.2 The solidifying pin is made of box and plate with a thickness of 2mm respectively. 5.1.3 Bracket: Support the level punching box and full and maintain its height direction as an auxiliary 5.22 Social Measuring cup: volume (V: 1a3ml±C, 3ml inner diameter is 3.mr. 5.3T industry half, maximum weighing pan 530 sense proof 3mg5.4 calibration table, create plate ruler.
6 measurement plan
6.1 independently carry out three times of hot determination, take the average platinum 6.2 the dragged and mixed magnesium powder is continuously evenly controlled to be placed on the support to ensure that the magnesium powder mouth passes through the 00um aperture net and falls on the inner wall of the pain bucket to the material shortage that has been pressed (the cup 43-80 is within the full plate cup, De Dingyi City standard move! Set movement, proof control 6.3 use the screen plate ruler when ten products standard plane gently scrape the excess magnesium powder on the top of the pool, weigh the total mass of the powder and the amount of puff (m), accurate to n.1 ：
Analysis and calculation
The loose powder is calculated according to the following formula
CB/T 4107—2004
In the formula:
The mass of the powder and the measuring cup, in grams (unit); the mass of the measuring cup, in grams (unit):
The volume of one portion (the main part of the measuring rod) is cubic length (m) 15X15
150 X 300
