The State Economic and Trade Commission of the People's Republic of China issued Foreword
The provisions of 1.1 and 1.3.2 of the standard are strictly enforced, and other provisions are strictly enforced. This standard replaces the mandatory chemical industry standard HG3209-1886. General technical conditions for ceramic equipment in practice: HG3209-202
This standard adopts the industry standard JISR-931 acid ceramics for chemical industry. It can be customized to HG3809-193. The main technical differences between this standard and HG3209-196 are: the material classification is changed from three categories to four categories, and the addition of the second category Category 1 will be divided into categories 2.3 and 4 according to categories 1 and 2.8 in the standard: the technical performance indicators remain unchanged:
The technical requirements have been added with the "allowable deviation of the size". The test method has been supplemented with the following provisions: 1. The internal wear of the test plan has been modified and supplemented. 2. The marking, labeling and packaging methods have also been supplemented and improved. This cup was approved by the Policy and Regulations Department of the former State Petroleum and Chemical Industry Bureau. This standard was proposed by the Technical Committee for Standardization of Chemical Equipment. The drafting list of this standard was proposed by Jiangsu Yixing Chemical Machinery Factory, Tianhua Chemical Machinery and Zige Chemical Research and Design Institute, and Banxiang Chemical Filling Science (Group) Company.
The main drafters of this standard are: Zhang Longshun, Li Hongfa, and Chen Jia. This standard 19 It was first published in 1980 as the chemical industry standard 2B4002-1986, and was adjusted to a mandatory chemical industry standard in 1997 and renumbered as H(320-[586

There are no appearance defects of ceramic products, and the shape and size deviations are measured and calculated with the same accuracy and checked daily. 5.2
5.3 The aging test of acid-resistant ceramic products shall be carried out by partially hollowing out the acid-resistant ceramic products and hitting various parts of the products with a small iron wheel to listen to whether the sound is a sound of grinding or a sound of sand. 5.4 Other tests shall be carried out in accordance with the relevant provisions of the corresponding product standards. 6 Inspection rules
According to the inspection classification
The inspection of acid-resistant ceramic products is divided into two types: type inspection (factory inspection) and type inspection. 6.1.1 Common inspections
Ceramic product output Before the product is put into production, a routine inspection must be carried out. The contents specified in 4, 2, 4.3, and 4.4 are routine inspection items. 6.1.2 Type inspection
The type inspection items of the product are all the contents of the technical requirements. Under normal circumstances, the type inspection shall be carried out once a year. When one of the following situations occurs, the company shall conduct a type inspection: a) Test and complete type identification of new products or old products transferred to the factory for production. 61
11G3209—2002
1) After formal production, if there are significant changes in structure, raw materials, and processes that may affect product performance, c) When the product is resumed after a long period of production. d) When the inspection results are significantly different from those of the previous type inspection. d) When the national quality technical supervision agency issues type inspection requirements. 6.2 Grouping and batching
6.2.1 Grouping
Products of the same specification and a certain number (the number varies with product size and batch) produced under the same process conditions are grouped into batches. The minimum batch size shall meet the requirements of the corresponding product standards. If it is less than a batch, it shall be determined by negotiation between the supply and demand parties. 6.2.2 Samples required for each control test item shall be selected from the grouped batches by random selection: the specimens for non-destructive tests can be used for the inspection of other items after inspection.
6.3 Material determination rules
6.3.1 The physical and chemical properties of acid-resistant ceramic products during the inspection shall meet the requirements of the corresponding product standards. 6.3.2 When all the physical and chemical performance test items of acid-resistant ceramics meet the requirements, the grouped products shall be judged to be qualified: if one item is not qualified, the product shall be judged to be qualified.
6.3.3 When the number of shape and size deviations, appearance quality and sound quality failures does not meet the specified number of failures, a second sampling re-inspection can be carried out in accordance with the relevant product standards. If the re-inspection is qualified, the batch of products will be judged to be qualified, otherwise the batch of products will be judged to be unqualified. .3.4 For all products that are rejected due to internal quality, sound and size inspection, the supplier shall re-inspect the entire piece and re-deliver them to the village in accordance with the temporary regulations. .7 Marks and labels
7.1 According to the characteristics of acid-resistant porcelain products, the packaging method shall be marked with corresponding marks and labels. 7.2 The markings and labels of the products shall include the following:
1) Name of the manufacturer and address of the company.
2) Product specification model code, batch number.
3) Inspection mark
4) Inspection mark
5) Inspection mark
6.3 Product packaging marks need to be packed with the following: 8) Shipping and receiving marks.
1) Transportation graphic mark:

B Packaging and storage
8.1 Packaging
1.1 Acid-resistant porcelain products are usually tied with straw ropes, joints, and other equivalent pressure materials to make dry packaging for transportation. 8.1.2 Products with durability requirements can be packed with wooden screens or connected with flooding. The requirements of the effective agreement are as follows: 8.1.3 The following documents must be provided with the packaged products: a Product inspection certificate.
L) Product Instructions,
e>Packing sheet.
8.2 Transportation
8.2.1 The storage ends of acid-resistant products should be flat, especially away from heat sources, to avoid local damage.8.2.2 Measures should be taken for storage of products in cold weather to prevent internal water accumulation and freezing cracking.
8.2.3 Only single-unit container products are allowed to rotate, and other products can be properly fixed. HG 32092002
8.2.4 During the packaging and transportation of acid-resistant porcelain products, care should be taken to avoid damage caused by strong vibration and filtration.
