For dated references, only the version corresponding to that date is applicable to this document; for undated references, the latest version (including all amendments) is applicable to this document. GB/T 699, Quality carbon structural steels GB/T 1480, Metallic powders - Determination of particle size by dry sieving GB/T 2967, Cast tungsten carbide powder YS/T 412, Cemented carbide pellets3 Terms and definitionsNo terms and definitions need to be defined in this document.4 Product classificationWelding rods are divided into four designations according to the type of hard particles: HTYZ, HTYQ4, HTYQ6, and HTYQ7, as shown in Table 1. 7.4.2 When the hard particle size test result is unqualified, double sampling shall be taken in the batch of products for repeated inspection of the unqualified items. If any item is still unqualified in the test result, the batch of products shall be judged unqualified. 7.4.3 When the test result of filling rate of the welding rod is unqualified, double sampling shall be taken from the batch of products for a repeated inspection of the unqualified items. If any item is still unqualified in the test results, the batch of products shall be judged unqualified. 7.4.4 If the inspection result of the welding rod size and allowable deviation is unqualified, the welding rod shall be judged as unqualified. 7.4.5 If the inspection result of the welding rod appearance quality is unqualified, the welding rod shall be judged as unqualified.8 Marking, packaging, transportation, storage andaccompanying documents 8.1 Marking The following markings (or labels) shall be placed on the product packaging: a) name and address of the supplier; b) product name and designation; c) batch number; d) net weight; e) number of this document. 8.2 Packaging The product shall be packed in anti-rust paper (or kraft paper), put into a double-layer plastic bag or an aluminum-plastic bag, and vacuumized, and then put into a plastic box or a cardboard box.
