5.3 For holes in clothes that are difficult to mend, the operator should agree with the consumer in person on the expected effect after mending and confirm it in writing.
6 Method for measuring the length of clothing mending
6.1 The edge length of the hole shape is measured at least as 1cm; if less than 1cm, it is measured as 1cm.
6.2 The general hole length is calculated as (length + width) × 2.
6.3 For triangular holes with the longest side less than 3cm, the hole area is calculated as a square hole. For the longest side longer than 3cm, the actual measured length is used, and the area is calculated according to 6.5 and 6.6.
6.4 For vertical slit-shaped holes, if the width is less than 1cm, it is measured as 1cm; if more than 1cm, the actual measurement is used.
6.5 For horizontal slit-shaped holes, if the width is less than 1cm, it is measured as 1cm; if more than 1cm, the actual measurement is used. The length is calculated as (length + width) × 2 × 150%.
6.6 Slant-shaped holes are measured as square holes. The length is calculated as (length + width) × 2 × 120%.
6.7 For holes with a perimeter exceeding 10cm, the length is calculated as (length + width) × 2 × 120%.
