1、BSI Standards PublicationBS ISO 5433:2013Leather Bovine wet blue SpecificationBS ISO 5433:2013 BRITISH STANDARDNational forewordThis British Standard is the UK implementation of ISO 5433:2013. It supersedes BS ISO 5433:1999 which is withdrawn.It is considered the view of the UK committee that the ap
2、plication of this standard to bovine wet blue can be limiting on three counts:1. The requirement for a water extract pH value of greater than 3.5 isconsidered restrictive as tanners are producing high quality bovine wetblue with water extract values of less than 3.5, such as a pH value 3.2.2. It sta
3、tes that a 3.5 % chrome content is required to achieve a 100 C shrinkage temperature. However, this shrinkage temperature is being commercially achieved at a chrome content of 3 %.3. At the request of their customers, tanners are not placing trade namesor names and addresses of the manufacturer on t
4、heir packaging. Thelabelling requirements of the standard do not reflect the commercialrealities that tanners operate within and would require the tanner andcustomer to disclose this information without any perceived benefit.It is acknowledged by the UK committee that this standard can be applied fo
5、r UK commercial transactions and aspects can be used in case of dispute between parties but all parties should be aware of the limitations detailed above for bovine wet blue production.The UK participation in its preparation was entrusted to Technical Committee TCI/69, Footwear, leather and coated f
