Main technical requirements of QB/T 2880-2024 Children's leather shoes
| No. | Item | Test method | Requirement |
| 1. | Appearance quality | GB/T 3905.5 | For details, see the requirements of Table 1 of 5.2 of QB/T 2880-2024 |
| 2. | Flexing resistance | GB/T 3903.1 | Non-leather outsole: The length of the cut-crack after folding should not be greater than 20.0 mm. The length of new cracks after folding should not be greater than 5.0 mm, and the number of new cracks should not exceed 3. There should be no crazing, grain cracking, damage, etc. and there should be no layering of the upper and coating. Debonding should not occur at the joints of the upper and sole, foxing, welt and bottom wall. There should be no debonding on the sole and no layering of the composite sole. The coating of the sole and bottom wall should not crack or peel off. |
| Leather outsole: A single crack should not be longer than 5.0 mm and the number of cracks should not exceed 3. After folding, there should be no crazing, grain cracking, damage, etc., and there should be no layering of the upper and coating. Debonding should not occur at the joints of the upper and sole, foxing, welt and bottom wall. There should be no debonding on the sole. The coating of the sole and bottom wall should not crack or peel off. | |||
In one of the following cases, the folding resistance is not tested:
| |||
| 3. | Abrasion resistance | GB/T 3903.2 | The length of abrasion should not be greater than 15.0 mm. There should be no abraded through on the soles. Natural leather outsole is not tested for abrasion resistance. |
| 4. | Peeling strength | GB/T 3903.3 | For children's leather shoes manufactured by sewing, adhesive seaming or special processes (such as riveting), the peel strength is not tested. The peel strength should not be less than 40 N/cm. When the material has been torn but the peeling layer does not open, the peel strength should not be less than 30 N/cm. |
In one of the following cases, the upper pull-out strength is measured instead of peeling strength:
| |||
| 5. | Upper pull-out strength | QB/T 2880-2024 6.5 | For children's leather shoes manufactured by sewing, adhesive seaming, or special processes (such as riveting), the upper pull-out strength is not tested. The upper pull-out strength should not be less than 70 N/cm. When the material has been torn but the joint part of the upper and sole does not open, the pull-out strength of the upper should not be less than 30 N/cm. |
| 6. | Outsole hardness | GB/T 3903.4 | The hardness of the outsole of the solid material should be 45 Shore A~65 Shore A. The hardness of the outsole of the microcellular foam material should be 45 Shore C~65 Shore C. The composite bottom should meet the hardness requirements of the solid core bottom and/or microporous foam bottom according to the type of material. |
| Natural leather outsoles and children's leather shoes with a thickness of less than 3 mm (excluding patterns) are not tested for outsole hardness. | |||
| 7. | Adhesion between outsole and midsole | GB/T 21396 | The adhesive strength between the outsole and the outer midsole should not be less than 20 N/cm. When the microporous sole has been torn but the adhesive layer is not opened, the strength should not be less than 15 N/cm. |
| 8. | Flexing index of fibrous board | QB/T 1472 | Should not be less than 1.9. |
| 9. | Color fastness to rubbing of lining and insock | QB/T 2882-2023 Method A | Should not be less than grade 3. |
| 10. | The low-temperature flexing resistance performance of the whole shoe | QB/T 4547-2021 | The low-temperature flexing resistance of children's leather shoes claiming to have cold-proof performance should meet the requirements of 4.1 in QB/T 4547−2021. |
| 11. | Shanks | Shanks GB/T 28011 (Shanks), QB/T 4862 (Injection Midsole) | Children's leather shoes with a heel height greater than 20.0 mm and the heel breast greater than 8.0 mm, shanks or other rigid support materials shall be installed. The heel breast should not exceed 15mm. |
| The length, longitudinal stiffness, hardness, and bending properties of the shanks should meet the requirements of GB/T 28011. | |||
| The shanks of the injection midsole children's leather shoes are not required, and the longitudinal stiffness of the injection midsole should meet the requirements of QB/T 4862. | |||
| The shanks of the wedge heel shoes do not need to be tested. The shanks of the shoes with wood soles and rigid plastic molded soles (with a hardness of ≥ 80 Shore A) do not need to be tested. | |||
| Note: Infant leather shoes do not require No. 2-11 physical and mechanical properties | |||
