Scope

1.1 This standard specifies the measurement of the performance change of
plastic specimen as immersed in liquid chemical reagent without being affected
by external influences. This standard does not include the environmental stress
cracking test (ESC) as specified in ISO 22088-2:2006, ISO 22088-3:2006, ISO
22088-4:2006.
1.2 This standard only applies to the determination of the specimen the surface
of which is completely immersed in liquid chemical reagents.
Note: This method may not be suitable for partial immersion or intermittent immersion
of plastic specimens.
1.3 This standard applies to all solid plastics, such as molded or extruded
plastics, sheets, tubes, rods or sheets which have a thickness of more than 0.1
mm. This standard does not apply to porous plastic materials.

Summary	This standard specifies the immersion in liquid chemicals in performance caused by changes in the determination. This standard does not include ISO 22088-2-2006, ISO 22088-3-2006 and ISO 22088-4-2006 prescribed test environmental stress cracking (ESC). This standard applies only to the sample surface is completely immersed in a liquid chemical reagents case determination. Note: This method may not work for local soaked plastic specimen or intermittent moistened. This standard applies to all solid plastic, such as molding or extrusion molding plastic, sheet, pipe, rods or thicker than a sheet of 0. 1mm. This standard does not apply to porous plastic materials.
