5.4 Stitch length

Use a straight steel ruler to measure on any 30 mm in any location of a finished product (except thick-thin locations and embroidery locations).

5.5 Other items

Use the sense organ and a measuring ruler for inspection.

6.1 Batching

Use the same material for production; use products to form an inspection batch, which are produced using the same production process and of the same style and the same colour.

6.2 Exit-factory inspection

Carry out inspection before delivery; products can only be delivered when they pass the inspection and are accompanied by a compliance certificate (or an inspection certificate).

6.3 Routine type inspection

6.3.1 Inspection cycle

the usability of products and have little effects on products’ appearance, are called slight defects b) General defects the defects which do not meet this Standard to a larger degree, but will not affect the usability of products and have slight effects on products’ appearance, are called general defects c) Severe defects the defects which reduce and affect the basic usability of products to a significant degree and affect products’ appearance severely, are called severe defects

6.5.2 Criteria for defects

a) Slight defects the defects whose quantitative indexes are within 50% (inclusive) exceeding standard values. In the qualitative indexes, they are not in conformity with this

Standard to a slight degree.

b) General defects the defects whose quantitative indexes are above 50% and within 100% (inclusive) exceeding standard values. In the quantitative indexes, they are not in conformity with this Standard to a larger degree. The cases in which the representation method of size designations does not comply with the national standard, are all called general defects.

c) severe defects the defects whose quantitative indexes are more than 100% exceeding standard values. inconformity with the compulsory standard; foreign odour exceeding standard; severe hair-slip; severe dyeing defect and greasiness; relatively severe, large areas of damage; glue failure and permeation in locations where adhesive lining is used; large areas of fracture, crazing, de-coating, etc. of the surface of leather and double face; broken sewing thread of more than 15 mm, damaged zipper, etc. in finished products, are all severe defects.

NOTE. Quantitative indexes are those which are specified in numerical values in this Standard.

Annex C (Normative)

Test method for woven fabric seam slippage degree

C.1 Principle

Apply a certain load vertically in the seam direction of a garment (or a sewing sample) to make the seam split, and then measure the maximum distance of splitting.

C.2 Applied load

The load for liner is (100 ± 2) N.

The load for fabric is (70.0 ± 1.5) N.

C.3 Instruments and tools

C.3.1 Fabric bursting strength tester. its clamp distance can be adjusted to 10.0 cm;

the travelling speed of its clamp under no load can be adjusted to 5.0 cm/min; the pre- tension (of hammer) is 2 N; the effective clamping area of the clamp for samples is 2.5 cm × 2.5 cm.

C.3.2 Sample cutting scissors.

C.3.3 Straight steel ruler of division value 1 mm.

C.4 Test environment

Carry out conditioning and test in standard atmosphere. temperature (20 ± 2)°C;

relative humidity (65 ± 4)%.

C.5 Test requirements and preparations (sampling location)

C.5.1 Sample size. 5.0 cm × 20.0 cm, whose straight-direction centre line is perpendicular to the seam stitch.

C.5.2 Test quantity. cut 3 pieces from each sampling location from a finished garment (or a sewing sample).

C.5.3 Sampling locations. as specified in Table C.1.
