diameter. Use ruler or measuring tape or other measuring tool of corresponding
size precision to measure length.
4.3 Welding performance
Test method for deposited metal X-ray flaw-detection of coil wire and hollow coil
wire is in accordance with Annex B. Test method for plate stack welding of
straight wire shall be in accordance with Annex C.
4.4 Appearance quality
Visually inspect or use 20-times magnifying glass to check wire’s appearance
quality. In arbitration, use 20-times magnifying glass.
4.5 Wire coil
Use measuring tool that can guarantee corresponding precision to measure
size deviation of wire coil. Visually inspect other items.
4.6 Coiling requirements
Coiling requirements shall be visually inspected. When necessary, use
measuring tool of corresponding precision to measure.
5 Inspection rules
5.1 Inspection and acceptance
5.1.1 Wires shall be inspected by supplier to ensure wire quality comply with
provisions of this Standard and order sheet (or contract). Fill in quality certificate.
5.1.2 Purchaser inspect received wires according to provisions of this Standard.
When inspection results fail to meet this Standard or order sheet (or contract),
it shall propose to supplier in written form. It shall be solved by supplier and
purchaser via negotiation. Objection about appearance quality or size deviation
shall be proposed within one month since wires are received. Objection about
other performance shall be proposed within three months since wires are
received. When arbitration is required, it shall be entrusted to a third
organization that is recognized by both parties to conduct arbitration. Conduct
sampling together at purchaser’s site.
5.2 Batching
Wires shall be submitted for acceptance in batches. Each batch shall be
composed by wires of same designation, of same melting time and of same
dimensions. Batch weight is not limited.
after being agreed by supplier and purchaser, this batch of wires shall be
inspected by supplier box by box (roll). The product inspected as accepted shall
be delivered.
5.6.4 When appearance quality of any wire fails, this box (roll) of wires shall be
rejected. But after being agreed by supplier and purchaser, this batch of wires
shall be inspected by supplier box by box (roll). The product inspected as
accepted shall be delivered.
5.6.5 When any wire coil fails, this batch shall be rejected. But after being
agreed by supplier and purchaser, this batch of wires shall be inspected by
supplier box by box. The product inspected as accepted shall be delivered.
5.6.6 When coiling requirements fail, this box (roll) shall be rejected.
6 Traceability
6.1 Supplier shall ensure production, inspection or test, delivery into warehouse
of any batch of wires, any wire traceable. Ensure that wire mark can be traced
back to raw data of wire manufacturing and inspection.
6.2 Supplier shall make safekeeping of various raw records for future reference.
The shelf life is not less than 3 years.
7 Marks, packaging, transport, storage and quality
certificate
7.1 Marks
7.1.1 Product marks
Print following marks (or stick labels) on outer packaging of wires that are
inspected as accepted, indicating:

c) reference to this Standard;
d) certification mark;
e) product’s melting time number, lot number;
f) inspection seal of supplier’s quality inspection department (or signature or
seal of quality inspection personnel);
g) use permanent mark to mark wire’s alloy designation on end of each
straight wire.
7.1.2 Packaging box marks
Packing box marks of wires shall comply with provisions of GB/T 3199.
7.2 Packaging, transport, storage
Use aluminum foil vacuum packaging or plastic bag vacuum packaging to pack
wires first. Then load into paper packaging boxes. Condition for storage is:
humidity is not greater than 60%. Or packaging is according to the one agreed
by supplier and purchaser. Other packaging, transport, storage requirements
are in accordance with GB/T 3199.
7.3 Quality certificate
Each batch of wires shall be attached with product quality certificate, indicating:
a) supplier’s name;
b) product’s name;
c) designation and dimensions;
d) lot number;
e) melting time number;
f) net weight, or number of boxes, pieces;
g) reference to this Standard;
h) certification mark;
i) inspection results of each analysis item and inspection seal of supplier’s
quality inspection department (or inspection mark);
j) packaging date (or exit-factory date);
k) period of use (indicating that immediately use after it is unsealed; use
within one year in sealed state).
