This standard replaces JM/T3375-1991 Boiler Raw Materials Factory Inspection 3 Compared with JD/T3375-1991, this standard has the following main changes: ... Added definitions of factory inspection and related terms (Chapter 3 of this edition); : Principles for determining the factory inspection period (Chapter 3 of the 1991 edition; Chapter 4 of this edition); JB/T3375-2002
Modified and added factory inspection of domestic and imported materials (3.1.123.6 of the 1991 edition: 5 of this edition); .3, 5.4 and Chapter 6 and Chapter 7 simplify the number of inspections and the selection method of the inspection party to meet the qualified standard! Chapter 3 and 4 of the 1991 edition; Chapter 6.2 and Chapter 7 of this edition add the provisions for the arbitration of the problems caused by the acceptance of non-conforming bridges (Chapter 10 of this edition). This standard is issued by the China Machinery Industry Association. This standard is under the jurisdiction of the National Furnace Standardization Technology Committee (CSBTSITC73).

Rules for factory acceptance of boiler materials
JR/T3375—2002
This standard specifies the basic requirements for factory acceptance of boiler materials by steel furnace manufacturers, except for those otherwise specified in the order contract. This standard is applicable to the main core materials for fixed boilers, including: boiler guard pliers, boiler guard pliers, mold pins (No. 25 and above), steel (for manufacturing tie rods (suspenders with a diameter of 4m and above), structural steel plates (for manufacturing large plate beams, called plates) and welding materials (including rods, welding wires, flux-cored wires and fluxes). Other materials for fixed boilers may refer to the provisions of the standard for factory acceptance. 2 Normative references

3 Terms and definitions
The following terms and definitions apply to this standard. 3.1
Recelvingacceptancebzxz.net
The boiler manufacturer confirms the purchased materials through verification and (or) inspection. 32
Supplementaryrequiranentmaterials are not specified in the product standard and are selected by the boiler manufacturer when necessary. 3.3
AdditionalrequirementAdditiunalrequirementThe requirements are not specified in the product standard and are agreed upon by the steel boiler manufacturer and the material supplier. 4 Principles for determining factory acceptance items
4.1 The boiler manufacturer shall verify the quality certificates and marks of all the boiler materials used in the factory. 4.2 The boiler manufacturer shall determine the inspection items in accordance with this standard, material production standards and the provisions of the order contract. 4.3 The boiler manufacturer shall report the needs of the product in the design and manufacturing, and list the supplementary requirements and additional requirements in the order contract as inspection items.
4.4 For materials with complete certificates and confirmed quality, the boiler manufacturer's quality management department shall propose 1, and the inspection items and the inspection quantity may be appropriately reduced or increased after approval by the technical person in charge of the factory. 5 Verification of material quality certificates and marks
5.1 Inspection items and the inspection quantity may be appropriately reduced or increased. All materials should be accompanied by a quality certificate: documents without a quality certificate should be collected. 1 Product standards and quality certificates for domestic materials Standard serial number
