3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
bust girth
the maximum size measured by a circle horizontally through the most plump point of breast in case people wears fitted brassiere which is single-layer, packless and without support to make the breast in natural state
3.2
underbust girth
the size measured by a circle horizontally at the breast root
3.3
brassiere cup
the part of brassiere covering breast
3.4
under border
The part of brassiere covering underbust girth position of human body
3.5
lateral wing
the part of brassiere covering from the armpit aside the breast to the back
4 Type and Specification
4.1 Type
4.1.1 The type of brassiere is expressed with the brassiere cup code and the bust girth, for example, A75 represents brassiere with brassiere cup of Type A and underbust girth of 75cm.
4.1.2 Brassiere cup code represents the difference between bust girth and underbust girth fitted with human body, see Table 1.
Table 1 Brassiere Cup Codes
In mm
Brassiere cup code AA A B C D E F G
Difference between bust girth and underbust girth 7.5 10.0 12.5 15.0 17.5 20.0 22.5 25.0
4.13 75cm is selected as reference number for underbust girth, and different sizes are divided through increasing or decreasing successively by 5cm.
4.2 Specification
4.2.1 See Annex A for names of brassiere parts, and see Table 2 and Figure 1 for the specification measuring positions and requirements (the pattern in Figure 1 is for illustration only).
Table 2 Specification Measuring Positions and Requirements
Specification Measurement method
Under border length a Spread brassiere naturally and measure along lower edge of brassiere (measure minimum size for adjustable type)
Shoulder strap length b Measure the total length of shoulder strap (measure the minimum size for adjustable type)
Figure 1 Schematic Diagram for Specification Measuring Positions of Brassiere
4.2.2 Left side of product shall prevail for the measurement of specification and size.
5 Requirements
5.1 Requirements consist of inherent quality and appearance quality. The inherent quality covers indexes such as fiber content, formaldehyde content, pH value, peculiar smell, decomposable carcinogenic aromatic amine dyes, color fastness to water, color fastness to soaping, color fastness to rubbing and color fastness to perspiration, while the appearance quality covers indexes such as specification and size deviations, size difference in symmetrical positions and surface defect.
5.2 Grading requirements
5.2.1 Brassieres are graded into high-grade product, first-grade product and qualified product.
5.2.2 The inherent quality is graded by batches while the appearance quality is graded by pieces, according to combination of which, the minimum grade shall prevail.
5.2.3 For all inherent quality indexes, the lowest test result shall be regarded as the grading criterion for this batch of products.
5.2.4 Where appearance defects with different quality grades are found on the same product, the product shall be graded according to the lowest quality grade.
