This standard adopts Japanese industry standard TIST8U2 for safety improvement. 3. For the enterprise with G/T33911 rubber surface marked in the chemical industry, this standard is different from H:/T3081-1986 in terms of technical differences: addition of scope, referenced standards, etc.
The technical requirements and inspection rules for internal and external cooling are written in the text of the standard, and the ground, external cooling and boot thickness are assessed.
The physical mechanical properties such as tension, location, wear and radiation intensity are standardized, and the direct index of spraying degree is cancelled.
The quality assessment of the standard is revised into an assessment content. "An inspection rule has been added to the safety performance of the equipment. The standard was issued in 1986 and was put forward by the Technical Supervision Department of the former Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the National Rubber and Rubber Products Standardization Technical Committee. The drafting unit of this standard is: 1 Shanghai Rubber Research Institute. The drafter of this standard is the company.
This standard was first issued as a national standard in 195, and in 2003 it was a recommended chemical industry standard and abbreviated as a national standard.

is estimated. The minimum value is below 3, and the test period is not more than 19. The test is about 100 mn, and the upper and lower platforms are parallel. 4. 1.2 Sample
Extend the inner head of the product to the final layer by 25mm ± 3m. Take the remaining part as the test example, as shown in Figure 3,
The inner core depth
The diameter of the inner head of the sample is 22mn. The height should be calculated by the mud figure. Then put the sample in the center of the pressure test, and add 4V machine within 3~5min. The pressure can be quickly increased to 4000, and the height is specified.
