Notice on the approval and release of "Standards for Acceptance of Flood Control Reserve Materials" SL297-2004 and "Regulations for the Preparation of Quota of Flood Control Reserve Materials" SL298-2004
Shui Guo Ke [2004] No. 123
All units directly under the Ministry, water resources (water affairs) departments (bureaus) of provinces, autonomous regions and municipalities directly under the Central Government, water resources (water affairs) bureaus of cities with independent planning status, and water resources bureau of Xinjiang Production and Construction Corps: After review, "Standards for Acceptance of Flood Control Reserve Materials" and "Regulations for the Preparation of Quota of Flood Control Reserve Materials" are approved as water conservancy industry standards and are hereby released. The standard numbers are SI.297-2004 and SL 298-2004 respectively. This standard shall come into force on May 20, 2004. The standard text is published and distributed by China Water Resources and Hydropower Press. April 16, 2004
For a long time, flood control reserve materials have been accepted with reference to relevant national industry standards or enterprise standards. Since these standards cannot fully reflect the special performance and requirements of flood control reserve materials, they are inconvenient to operate in actual work and it is difficult to ensure the quality of flood control reserve materials. In response to this situation, the Office of the State Flood Control and Drought Relief Headquarters organized the compilation of the "Flood Control Reserve Material Acceptance Standard Recommendation". This standard consists of 5 chapters, 21 sections and 217 articles. The main technical content includes three categories of emergency materials, life-saving equipment, and small emergency machinery and tools required for flood control and rescue. This standard is an acceptance standard for commonly used flood control reserve materials. Temporary collection and use of materials and large-scale mechanical equipment during rescue are not within the scope of this standard. This standard is recommended in full.

Note 1: The stitch density of the bag mouth refers to the double-stranded thread stitching. If the single-thread stitching is used, the density is 10 stitches/10cm; Note 2: The stitching should be folded when it is not the edge of the cloth: Note 3: The bad cloth used to sew sacks is generally calendered: Note 4; The public moisture regain of sacks is 14%, which is only used for conversion of quality. The packaging and marking of flood-proof sacks shall meet the following requirements, 3.2.5
1 Every 100 pieces are one piece, tied in a "well" shape, and wrapped with sackcloth. The packaging should be flat, firm, without damage or stain. The product and certificate must be placed in each package.
2 Each package is printed with a white mark as follows: "Special sack for flood control (No. ×)" Specifications, quantity, weight, supervision unit, manufacturer, and production date. 3.2.6 When visually inspecting flood control sacks, sampling should be based on 50,000 pieces as a batch. If less than 50,000 pieces, the actual number should be used as a batch. Ten pieces are randomly selected from each batch, and one piece is selected from each piece.
3.2.7 The items and requirements for visual inspection are as follows: Packaging and markings should meet the requirements of 3.2.5. 1
2 The product certificate should be consistent with the product.
3 The size, weight, and stitching should meet the requirements of Table 3.2.2 and Table 3.2.4. 4 Appearance quality: Check that the jumper, broken thread and single thread length of the sack surface cloth are not greater than 10mm, and there are no warp and weft crossing or adjacent jumpers and broken threads. Each sack has no more than 2 jumpers and broken threads on one side.
5 Quantity counting: The total number of 10 pieces should not be less than 999. 6 Result determination: If the product meets the above requirements at the same time, the batch of products is qualified; otherwise, it is unqualified.
3.2.8 When sampling and testing flood control sacks, the sampling should be 50,000 pieces as a batch. If it is less than 50,000 pieces, the actual number should be used as a batch. 5 pieces are randomly selected from each batch, and 1 piece is selected from each piece.
3.2.9 The sampling test performance indicators should meet the requirements of Table 3.2.4. 3.2.10 The sampling test method should be implemented in accordance with GB731-87. 3.2.11 The sampling test result is determined by the average value of the sample test. The indicators of the measured items meet the requirements, and the batch of products is judged to be qualified. Among the measured items, if one indicator is unqualified, double the sample will be drawn to test the performance of the item, and the result of the re-test will prevail.
