Chromium(VI) Testing Services for Leather
Over 85% of leather produced globally is chrome tanned. Cr III produces a versatile and stable leather, ideal of multiple end uses. However, chromium VI (Cr 6) is the hazardous form of the element and can, under certain conditions, have the propensity to form through oxidisation of Cr III present in the leather. This can occur during several stages of the supply chain from poor process control in the tannery, through to exposure to conditions such as high temperature, low humidity and UV light. At Eurofins | BLC, we can help your business manage the risk of chrome VI in your supply chain.
Eurofins | BLC can test your leather products and samples for the determination of chromium through both BS EN ISO 17075.
BS EN ISO 17075, the internationally recognised method for the analysis of chrome VI in leather, has been updated and split into two parts:
- BS EN ISO 17075-1:2017: Leather – Chemical determination of chromium(VI) content in leather – Part 1: Colorimetric method and;
- BS EN ISO 17075-2:2017: Leather – Chemical determination of chromium(VI) content in leather – Part 2: Chromatographic method (Eurofins | BLC recommended)
Differences between 17025-1:2017 and 2:2017
Both methods state that if a leather sample is tested with both 17075-1 and 17075-2, the results obtained with 17075-2 are considered as the reference. The advantage of the method described in 17075-2 is that there are no interferences from the colour of the extract.
At Eurofins | BLC, it is our recommendation to use the Ion Chromatography method (ISO 17075-2) as standard.
