ISO 175:2010规定了将塑料试样（不受任何外部约束）暴露于液体化学品中的方法，以及确定此类浸泡引起的性能变化的方法。它不包括ISO 22088各部分所述的环境应力开裂（ESC）。 它只考虑浸没试样整个表面的试验。 它适用于以模塑或挤压材料、板材、管材、棒材或厚度大于0.1mm的板材形式提供的所有固体塑料。它不适用于多孔材料。

ISO 175:2010 specifies a method of exposing test specimens of plastic materials, free from all external restraint, to liquid chemicals, and methods for determining the changes in properties resulting from such immersion. It does not cover environmental stress cracking (ESC) which is dealt with by the various parts of ISO 22088. It only considers testing by immersion of the entire surface of the test specimen. It is applicable to all solid plastics that are available in the form of moulding or extrusion materials, plates, tubes, rods or sheets having a thickness greater than 0,1 mm.
