This standard is equivalent to 150138:5:233E. The content of this standard G1.1 requires S33 to be "folded". This standard makes the following modifications to 1S01385. The new standard uses "this standard" instead of "not strict standard" in order to make the international standard more convenient. Appendix 4 of this standard Appendix:
This standard was proposed by China Machinery Industry Federation, and this standard was drafted by Quanzhou Jinman and Feijinsuai Yiyun Chemical Industry Committee. The drafters of this standard are: J. Wei Zhiling, Zhong Na, Jiang Xinhua: Gn/T19353—2003/1S03806.1545 Corrosion test of glass glaze in closed system
This standard is for testing the performance of related products in a closed system with acidic medium. The temperature of the medium in the closed system is higher than its starting point, which is acidic! The wet materials must be actual wet materials. This standard is applicable to the test of the corrosion resistance of porcelain under weak alkali conditions, as long as the materials meet the general test requirements (.4, 4.1.2).
This standard specifies the basic test materials for the spray test to ensure that the test results are sufficient. The test method is to calculate the head weight per unit area over a single time period. Note: For the test of the system performance under heat and humidity conditions, see 3/T7)S)2744. The test method for the system performance under heat and humidity conditions is CTR

day.2 The arithmetic half-mean is calculated by practicing
3.2.1 The arithmetic mean of the loss rate per unit area can be calculated by the arithmetic mean of the power consumption per unit area. The difference between the minimum value and the minimum value is determined by the minimum measurement limit and the dynamic range. The actual single quantity in Table 1 accounts for the number of units. Table! The relative variation range allowed by the relationship between the single measurement value and the number of units

(Data summary Appendix:
This standard proposes a common advantage for users to design practical devices to meet the requirements of the product 《 The test speed reduction or frame work 1 technology control requirements, the document (see reference number 1, 21, 3 of the Federation of Textiles and Experimental Equipment: (B/17988.GB7989 and [S0) 271: the original test method is attached,! \ The time ratio test specification of the dynamic resource layer, A.2 The influence of reproducibility on the tooth capsule
In order to ensure that the test equipment is not narrowed for the reproducibility of the measured station, the test method should be limited to the maximum allowable error, the lower the upper limit The maximum relative deviation of the measured value from the actual value is used as a symbol. For the test parameters of the standard, the maximum difference or the maximum difference is only the difference between the test temperature and the temperature of the sample. The effect of the test result is not obvious. For example, the ratio of the pressure to the product is not the product. If the limit specified in this standard is maintained, see text 112. >, then the influence on the station is small. 1.3 The relationship between the speed and temperature can be fully expressed by the secondary analysis relationship of A-rhenius. It shows that the maximum relative error of the test rate within the humidity range and the value exceeding the standard is 1n0\:~1 is 0.1% and the test error is reduced as much as possible. This is called the corrosion rate of the two important technical workers who represent the limit of corrosion resistance. The period of determination should be 1m/n. A.4 The accuracy of the test method before the test is 1m/n. |The accuracy of the test method is defined as the maximum cumulative test error of the test method measured by all test persons, based on the time and sample. According to the law of distribution of the whole, the error of the measurement is calculated as follows: A+A
The meaning of the symbol m is as follows: 1
This standard specifies the maximum relevant error measured during the exposure period. If the maximum error is not selected, the total weight loss and exposure area or the total amount of the drug will be In 9,
Liu in the table to the provisions of 2Fm uniform management of the factory barrier layer single type called gate 7, reported source 6.37 the original head weight measurement accuracy, then the medical volume determination of the most accurate blue is 1, when the material is 7m", the state area of ​​the return value error should be less than 3.1n, when the individual test liquid exposure behavior mm tunnel shape is approximately flat and the volume of the building should be less than 3.m\. Purchase its diameter special signature course error is less than n, 7rA. 5 liquid phase and vapor phase burst
in the chemical, 1 process ten what happens, the feeling is divided into no old forbidden road and vapor phase recording drop, under the specified conditions, the currency area standard established by the existing test technology and consider the loyal standard given by the specification to determine the concentration of busy people satisfied. For the chemical 11 process all the uniqueness of the epidemic your external area a draw both the increase of the exposure and the machine ratio of ten people ten said the currency, the case volume not people "6 suitable for the amount of money and direct, so measured the savings The speed of creation is a generational change. The test period of the most popular steam is still in progress. The rich record is due to the benefits of humidity control and condensation wave color in the test. The old has been with the condensation rate of the ingredients. The mountain analysis grade preparation of the condensation grade teeth is arranged. The liquid is used under the same conditions. It is assumed that the maximum separation is determined.
