5.! Simple pressure filter should meet the requirements of this standard and be manufactured according to the samples and technical documents approved by the prescribed procedures. 5.2 The materials and external parts selected for simple pressure filter should have the supplier's certificate of conformity. When there are no qualified products, they can only be used after being inspected and qualified by the manufacturer:
5.3 When simple pressure filter is used for filtering beverages and pharmaceuticals, the selected material composition shall comply with the relevant provisions of the Food Hygiene Law. 5.4 The manufacture and acceptance of non-inductive acid-resistant wires must comply with the provisions of GH2100. 5.5 The welding of joints must be welded with welding rods that are equivalent to or better than the parent material. The mechanical properties of the welded specimens shall be tested in accordance with the provisions of GB/T2619, GB/T2651, GB/T2653, and GB/T2652. Cast steel welding chains shall be treated to prevent intergranular corrosion, and the intergranular corrosion tendency test shall comply with the provisions of GB4334.1 as required.
