CTI Analysis
The scope is clearer than the old version, and it avoids conflicting with QB/T 2880-2007 <children’s shoes ” leather”> by removing the children’s leather shoes (boots) and infant’s leather shoes (boots) from the scope.
Addition of new test items including odour, abrasion resistance of top lift, rubbing resistance of lining and insole, formaldehyde, azo dyes, minimum length of shank, and bending capability of shank to improve the standard, but enhance the requirement for enterprises at the same time. The new testing items include:
| Test items | Test component | Requirement | Method |
| Superior product | Qualified product | ||
| Odour | Finished shoes | 3 grade niobium | QB/T 1002 |

| Assembled top lift, density adze 0.9g/cm3 | Niobium 150mg | GB/T 26703-2011 | |
| Minimum length of shank | For women shoes: heel height above 20mm, heel breast is above 8mm. For man shoes: heel height above 25mm, heel breast is above 8mm | Comply with GB 28011 | GB 28011 |
| Bending capability of shank | Comply with GB 28011 | GB 28011 | |
| Rubbing colourfastness of lining and insole | Lining and insole | Wet staining Niobium 3 grade (suede Niobium 2 grade) | QB/T 2882 method A (wet rubbing 10 times) |
| Azo dyes | Textile | Niobium 20mg/kg | GB/T 17592, GB/T 19942 |
| leather | Niobium 30mg/kg | ||
| Free formaldehyde | With skin contact | Niobium 75mg/kg | GB/T 2912.1, GB/T 19941 |
| Without skin contact | Niobium 300mg/kg |
Modified some test methods and evaluation clauses to make the standard more suitable to the present technology and development process of leather shoe production, and to meet the increasing requirement of consumers for leather shoes quality.
For example modified flexing resistance evaluation requirements and added exemption clauses:
| Test items | Exemption Clause | Requirement | Method | |
| Superior product | Qualified product | |||
| Flexing resistance according to QB/T 1002-2005 | No | After flexing, the length of cut ≤12.0mm. No new crack and broken on outsole and upper and no de-bonding at feather line. | After flexing, the length of cut ≤30.0mm. New crack length on outsole ≤5.0mm and should not exceed 3 parts, no crack and broken on upper and no de-bonding at feather line. | GB/T 3903.1 |
| Flexing resistance according to QB/T 1002-2015 | 1. Shoe size less than 230mm; 2. Stiffness of finished shoes test according to stipulation of clause 8.4.1 in GB/T 20991-2007, the flexing angle less than 45°under 30N force. 3. Heel height more than 70mm. 4. The thickness at flexing line of sole more than 25mm. | After flexing, the length of cut ≤10.0mm. No new crack and broken on outsole and upper, no de-bonding at feather line, welt, bumper, no delaminating between layers of composite sole. The printing on outsole or bumper should not peel off. | After flexing, the length of cut ≤20.0mm. each new crack length on outsole ≤5.0mm and should not exceed 3 parts, no new crack and broken on outsole and upper, no de-bonding at feather line, welt, bumper, no delamination between layers of composite sole. The printing on outsole or bumper should not peel off. | GB/T 3903.1 |
Modified requirement and method for hardness testing on heel in compression molding sole, and added the exemption for this item.
| Test items | Exemption Clause | Requirement | Method | |
| Porous material | Solid material | |||
| Hardness of heel in compression molding outsole according to QB/T 1002-2005 | Heel height < 25mm | No | \ | GB/T 3903.4 |
| 25mm < Heel height < 50mm | ≥ 55 Shore A | |||
| 50mm<Heel height | ≥ 75 Shore A | |||
| Hardness of heel in compression molding outsole according to QB/T 1002-2015 | Heel height < 25mm | Using the inside heel or other reinforced material in molding sole | \ | GB/T 3903.4 |
| 25mm < Heel height < 50mm | ≥60 Asker C | ≥55 Shore A | ||
| 50mm<Heel height | ≥75 Asker C | ≥70 Shore A |
CTI Suggestion
After the 1st of March 2016 the production and sales of leather shoes should be according to the new version of product standard QB/T 1002-2015.
