New Chrome VI Heat Ageing Standard: ISO 10195:2018
If your business manufactures leather or leathergoods, you need to be aware of a new ISO standard, which has been published for the thermal pre-ageing procedure for leather in order to assess the propensity for chrome VI formation (“chrome VI heat ageing test”).
This new international standard for Chrome VI heat ageing is: ISO 10195:2018
Within the new chrome VI heat ageing standard, two sets of ageing conditions are given as options depending on the end use of the leather:
|
Method
|
Conditions
|
Recommended Use
|
|
A1
|
24 hours at 60 ±2 ºC and relative humidity less than 20%
|
General purpose ageing for leathers not subjected to critical conditions in manufacturing and/or transportation (gloves, garments, leather goods, handmade or fashion articles)
|
|
A2
|
24 hours at 80 ±2 ºC and relative humidity less than 10%
|
Ageing for leathers subjected to critical conditions in manufacturing and/or transportation (footwear, automotive, upholstery)
|
Please note; this thermal pre-ageing procedure does not simulate any real condition in leather production or use. It is applicable to all types of chromium tanned leather.

If your company is submitting samples for chrome VI heat ageing, please can you ensure that you advise which set of ageing conditions are required i.e. Method A1 or A2.
If the end use of the leather is not known or may be across multiple product types, it is our recommendation to use the A2 conditions as these are considered to be the most stringent.
Further information on chrome VI heat ageing and both methods can be provided by BLC’s Chemical Testing experts. You can contact BLC by telephoning +44 (0) 1604 679 999 or emailing [email protected] or by completing the contact form at the bottom of this web page.
