SATRA releases revised test methods

Reporting on two revised methods to assess the density of footwear materials.

The SATRA TM68:1992 – 'Density of cellular materials' test method has been updated, to become SATRA TM68:2016 – 'Density of water absorbent cellular materials'. The scope has been changed to cover cellular materials with an open cell structure which would absorb water. It is recommended that non water absorbent (closed cell) materials are tested in line with a displacement technique such as SATRA TM134:1998 (2010) – 'Density of materials by volume displacement', which is often more convenient and which also carries a lower uncertainty of measurement.

Another recently revised test method is SATRA TM12:1993 – 'Density of leather and insole materials', which is now called SATRA TM12:2016 – 'Density of leather, leatherboard and insole materials'. In line with its new title, this test method now embraces materials made from leatherboard (bonded leather or reconstituted leather), such as may be used for shoe soles. The density identified is of intrinsic interest, and also essential for converting mass loss to volume loss in some abrasion resistance tests.
