GB/T 3190. In the calculation of "Al" content, take the sum of the analytical value of conventional analyzed elements and unconventional analyzed elements (which are doubted to exceed the limit value) as the "sum of element content".

4 Test Methods

4.1.3 The determination of analytical value shall adopt rounding-off comparison method. The rules of numerical value rounding-off shall comply with relevant stipulations in GB/T 8170. The rounding-off digit shall be consistent with the digit of limit value that is stipulated in Table 4 in this Standard, or GB/T 3190.

4.2 Dimensional Deviation

4.2.1 Use a measuring instrument with the accuracy of not lower than 0.01 mm to measure diameter.

4.2.2 Use a ruler or tape measure to measure length

4.3 Room-temperature Tensile Mechanical Properties

Room-temperature tensile mechanical properties shall comply with the method stipulated in GB/T 4909.3.

4.4 Electrical Resistance

Electrical resistance shall comply with the method stipulated in GB/T 3048.4.

4.5 Bending Performance

Bending performance shall comply with the method stipulated in GB/T 238.

4.6 Appearance Quality

Under natural scattered light, conduct visual inspection to examine appearance quality.

5 Inspection Rules

5.6.3 When any sample is disqualified in mechanical properties, take a double size of samples from that batch of products for re-inspection. When the result of the re-inspection is qualified, that batch of products shall be determined as qualified. If there are still samples that are disqualified in the re-inspection result, then, that batch of products shall be determined as disqualified.

5.6.4 When any sample is disqualified in electrical resistance, take a double size of samples from that batch of products for re-inspection. When the result of the re-inspection is completely qualified, that batch of products shall be determined as qualified. If there are still samples that are disqualified in the re-inspection result, then, that batch of products shall be determined as disqualified.

5.6.5 When any sample is disqualified in bending performance, take a double size of samples from that batch of products for re-inspection. When the result of the re-inspection is completely disqualified, that batch of products shall be determined as qualified. If there are still samples that are disqualified in the re-inspection result, then, that batch of products shall be determined as disqualified.

5.6.6 When any product is disqualified in appearance quality, then, that coil shall be determined as disqualified.

5.1 Inspection and Acceptance Inspection

5.1.1 Products shall be inspected by the supply-side, which shall guarantee that product quality complies with the stipulations of this Standard and the order form (or contract). In addition, a quality certificate shall be filled out.

5.1.2 The demand-side shall inspect the received products in accordance with the stipulations in this Standard. When the inspection result is inconsistent with what is stipulated in this Standard or the order form (or contract), this shall be proposed to the supply-side in the written form and solved by the demand-side and the supply-side through negotiation. Objections regarding appearance quality or dimensional deviation shall be proposed within 1 month upon receiving the products. Objections regarding between the demand-side and the supply-side, this batch of products may receive coil- by-coil inspection by the supply-side, and qualified products may be delivered.

6 Marking, Packaging, Transportation, Storage and Quality Certificate

6.1 Marking

Each coil of wire that passes the inspection shall be attached with a label, which indicates:

a) The supply-side's name;

b) Product name and designation;

c) Specification;

d) Exit-factory batch No.;

e) Exit-factory date;

f) Serial No. of this Standard. […]
