GB/T 22889-2008 《Leather - Physical and mechanical tests - Determination of surface coating thickness》 Related products

The GB/T 22889-2008 standard describes in detail the method of measurement of Coating thickness on the surface of leather. The standard applies to all kinds of coated leather, by cutting the leather vertically and measuring Coating thickness using Optical inspection or Electron Scanning Microscope (ESM). The measured results can be expressed directly as Coating thickness or calculated as a percentage of Coating thickness to total thickness. The standard specifies specific instrumentation, sampling and specimen preparation methods, and provides detailed operating procedures and presentation of results. The test report should include the average value of the coating and total thickness, Coating thickness as a percentage of total thickness, test conditions and possible deviations and sample description information.
