ASTM D3495 – Standard Test Method for Hexane Extraction of Leather
Description:
Significance and Use
3.1 This test method measures the amount of hexane-soluble lubricant present in all types of leather. Adequate lubrication prevents abrasion of leather fibers during flexing. This lubrication is generally obtained from the fat liquor added at the tannery. Some lubrication is also obtained from natural grease produced during the life of the animal.
Scope
1.1 This test method covers the quantitative extraction of all types of leather with hexane. This test method does not apply to wet blue.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
