CB11835·1998
This standard is a revised version of G11835-89. In terms of technical content, it adopts the rock wool content of Japanese standard 15A501-1995 artificial mineral fiber thermal insulation materials in a non-equivalent manner. Compared with GB11B35-89, this standard has been revised as follows: the conclusion and description of the standard have been modified according to GB/T1.1-153 and GB/1.3-199, and the appearance, diffuse filtration content and pipe eccentricity clauses have been added. The ball content, thermal conductivity and average fiber diameter indicators have been improved. The acceptance rules have been revised, and the "maximum use temperature" has been changed to a more accurate "heat load acceptance temperature". The relevant parts of this standard are standard derivatives. This standard will replace GB11835-89 from the date of implementation. This standard is proposed by the State Bureau of Building Materials Industry and is under the jurisdiction of the State Insulation Standardization Technical Committee (CSBTS/TC19I). The responsible unit of this standard is Nanjing Fiberglass Research and Design Institute. The drafting units of this standard are CISEL (Guangdong) Bixi Products Co., Ltd., Beijing New Building Materials (Group) Co., Ltd., Taiyuan Mining and Grain Co., Ltd.

The arithmetic average of the results of 2 times of inspection is the arithmetic average of the results of 3 times of inspection. The arithmetic average of the results is the arithmetic average of the results. C3.1 All parts should be able to stand upright, and one performance item meets the requirements of the performance indicator, and one defect is counted. The quality requirements are judged by the average value of the test results. C3.2 The judgment of the performance such as length, width, diameter, thickness, density, pipe eccentricity, chain quality, etc. adopts the combined quality level (AQ1.) 15 times, and the judgment rules of the inspection are shown in Table C4. After the sample inspection, if the number of defects in a sample is less than or equal to the first qualified judgment number A in column C4 (column I), the above performance of the batch can be accepted. If the number of defects in the first quality is greater than or equal to the first qualified judgment number Rc ([rotten]), the batch is considered an unqualified batch. If the number of defects in the first quality is greater than c in column I and less than R in column N, the sample size should be increased to the total sample number given in table C, and the total column inspection results should be used for judgment. If the number of defects in the total sample is less than or equal to the total sample qualified judgment number Ac given in column V of table C4, the batch can be accepted. If the number of defects in the total sample is greater than or equal to the total unqualified judgment number (W), If the measured value of the first sample is qualified, the above performance items of the batch of products are judged to be qualified. If not, the second sample should be tested again. The average value of the two test results is used as the basis for determining whether the batch quality items are integrated or not. GB/T1835 C3 .4 The comprehensive judgment rule for batch quality is that all quality measures of the batch must meet the acceptable quality requirements specified in C3.2 and C3.3 at the same time, otherwise the batch is judged to be unqualified.
