Introduction  
 
Provisions under Chapter 5 of th e Standard are mandatory for enforcement (but PH limit is 
regulated for recommendation), and the ot her provisions are recommendatory for 
implementation. The Standard shall not be  deemed as equivalent to EN14602:2004 
Footwear-Test methods for the assessment of  ecological criteria, 2002/231/EC Establishing 
revised ecological criteria for award of the Community eco-label to footwear and amending 
Decision 1999/179/EC, or ame nding  Decisions  2002/231/EC ，2002/255/EC ，
2002/371/EC ，2003/200/EC and 2003/287/EC in order to  prolong the ecological criteria 
for the award of the Community eco-label to certain products in terms of consistency.  
Appendix A and B attached to the Standard are normative appendices.  
The Standard was proposed by the China Petrol eum and Chemical Industry Association and 
archived by the Technical Sub-committees of Rubber Shoe s under the Standardisation 
Committee of Chinese Rubber and Rubber Produc ts. It was jointly drafted by a host of 
companies and organisations, including the Shanghai Institute of Quality Inspection and Technical Research, Qingdao Hicorp Group, Shanghai Warrior Shoes Co., Ltd, the Qingdao 
Double Star Corp. Jihua 3537 Shoe-making Co.,  Ltd, the Zhejiang Renben Shoes Co., Ltd, 
the Putian-based China National Testing Cent re for Footwear, and the Wenzhou-based 
China National Quality Testing & In spection Centre for Footwear.  
Specifically, major drafters include Xu Dejia, Zhang Ruohong, Sun Xu, Ma Qinghua, Ma 
Yanhong, Xu Bingde, Sha Shufen, Chen S ongxiong, Ni Bangguo, Tong Yugui, Huang Ying, 
Ji Hongchou, Cheng Qun and Jiang Wu. 
Health, Safety and Te chnology Specificatio ns for Rubber Shoes 
 
1. Scope   
The Standard stipulates terms and defin itions, classification, requirements, testing 
methods and sampling, as well as assessment of health and safety performance of rubber shoes.  The Standard applies to rubber shoes made  out of synthetic le ather, artificial 
leather or textile materials, and processed by hot vulcanisation techniques.  
2. Normative references  
The terms of the following documents shall be incorporated as part of the Standard after 
being referred in the Standard. Any document re ference with a specific date shall have its 
amendments or revisions (exc luding corrections) non-applicable  to the Standard. However, 
the parties are encouraged (on the basis of unanimous agreement) to discuss if the latest 
version can be applied to the Standard. Any document reference without any specific date 
shall have the latest versi on applied to the Standard.

3. Terms and definitions 
 
The following terms and definition ar e applicable to this Standard. 
 
3.1. Requirements on health and safety performance of rubber shoes 
Such requirements must be met so as to avoid a ny damage or risk to human health or safety.  
 
3.2. Infants’ rubber shoes 
“Infants’ rubber shoes” means footwear exclusively for children younger than 36-months 
old (normally they wear shoe s sized smaller than 170).    
4. Product classifications 
The products are classified into two cate gories in terms of customers’ age:  
——Category A: Infants’ rubber shoes ——Category B: Rubber shoes other than for infant use 
 
5. Requirements  
 
Health and safety performance of rubber shoe s shall meet the following requirements listed 
in Table 1. GB ××××—××××

reducing conditions. Refer to Appendix A for the list. 
b. Permissible limit for aromatic amines, PCP,  TeCP and N-Nitrosamine is 30mg/kg, 0.5mg/kg, 
0.5mg/kg and 0.5mg/kg respectively. 
c. Refer to Appendix B for a list of N-Nitrosam ines that should not be found in the rubber. 
d. According to Method A described in GB/T 2882-2007, drip sweat onto the rubber and rub it 50 
times before evaluating the level of colour  transfer with a standard grey scale. 
 
6. Test methods  
 
6.1. Test of PH value 
Follow relevant procedures in GB/T 7573-2002 for PH test of textile materials, artificial leather 
and synthetic leather. 
6.2. Test of free formaldehyde content  
Follow relevant procedures in GB/T 2912.1-1998 for the free formaldehyde content test of textile 
materials, artificial leather and synthetic leather.  
6.3. Test of extractable heavy metal content (Pb, Cd, As) 
Follow relevant procedures in GB/T 17593.1-2006 for the test of extractable heavy metal content 
(Pb, Cd). For the test of As content, follow the relevant procedures in GB/T 17593.4-2006. Content 
of the three heavy elements can be also tested according to GB ／T 17593.2-2007.

7. Sampling and test result assessment  
7.1. Sampling methods 
7.1.1.  Randomly select a mini mum number of finished shoes as required to take health 
and safety performance test.  
7.1.2.  Test must be done separately if materi als comprising upper, lining and innersole 
can be taken apart. If the upper and lining can ’t be divided, take the lining material 
for the test and assess the outcome.  
7.1.3.  If the sample materials taken from fini shed shoes fail to live up to test 
requirements, the same batch of materials us ed in the same part of the shoes can be 
tested.  
7.1.4.  The materials (or the location from which part of the shoes such materials are 
sampled) must be specified in the test report.  
7.2. Test result assessment 
7.2.1.  If the results of all test items meet the requirements listed in Table 1, the batch of 
products shall be considered to have passed the health and safety performance test.
