Children's canvas rubber footwear
1 Scope
This document specifies the classification, technical requirements, test methods,
inspection rules, marking, packaging, transportation, and storage of children's canvas
rubber footwear.
This document applies to footwear for toddlers and children made of soles made of
rubber or other elastomers as the main material and complete uppers made of fabric and
other synthetic or natural materials as the main material.

3 Terms and definitions
The terms and definitions defined in GB/T 33384-2016 and the following apply to this
document.
3.1 children's canvas rubber footwear
Canvas rubber shoes for children wearing, with a shoe size below 245.
[Source: GB/T 33384-2016, 2.2.2]
3.2 toddler's canvas rubber footwear
Canvas rubber shoes for toddlers aged 36 months and younger (usually shoe size is no
larger than 170).
4 Classification
4.1 Products are divided into two categories according to their wearing objects:
-- Category A: toddler’s canvas rubber footwear;
-- Category B: children's canvas rubber footwear other than toddlers’ canvas rubber
footwear.
4.2 Products are divided into solid soles and cellular soles according to outsole materials.
5 Technical requirements
5.1 Shoe size and model
They shall be in accordance with GB/T 3293.1.
opening circumference is ≥360 mm and sum of the depth and opening circumference is
≥584 mm, the average thickness is required to be ≥0.038 mm, and the thickness
measured each time shall not be less than 0.032 mm. Or there shall be clearly defined
holes in any area up to 30 mm×30 mm, and the total area of the holes shall account for
at least 1%.
NOTE: Not suitable for heat-shrinkable film used for wrapping shoes.
6 Test methods
6.1 Physical properties
6.1.1 Test conditions
They shall comply with the regulations of GB/T 2941 and HG/T 2198. The storage time
of the sample before testing shall not be less than 6 hours, and the pieces taken from
finished products shall be cut along the direction of the outsole.
6.1.2 Tensile strength and elongation at break
The test shall be carried out in accordance with the provisions of GB/T 528. The shape
of the sample is specified with a type 1 dumbbell cutter. When the thickness of the
sample does not meet the test method standard, the test is based on the actual thickness
of the sample.
6.1.3 Abrasion resistance
6.1.3.1 The test shall be carried out according to the provisions of GB/T 9867-2008
(Method A), and the detection pressure is (10±0.2)N for the solid sole and (5±0.1)N for
the cellular sole. The test parts are the force-bearing parts of the outsole, namely: the
metatarsophalangeal flexion part of the forefoot and the heel part of the backfoot.
6.1.3.2 Choose a flat surface for inspection. Surfaces with slight patterns but the pattern
depth does not exceed 0.5 mm can be regarded as flat surfaces.
6.1.3.3 For solid soles, if the depth of the outsole pattern is greater than 0.5 mm,
appropriate methods shall be used to polish the pattern before sampling and testing, and
this shall be noted in the result report.
6.1.3.4 For cellular soles, they shall not be polished. If the depth of the outsole pattern
is greater than 0.5 mm, the same batch of raw materials shall be taken for testing, and
the results shall be noted in the report.
6.1.4 Hardness
For solid soles, the test shall comply with the provisions of GB/T 531.1, and for cellular
