What is ISO 19064-2 about?
ISO 19064-2 is the second part of a multi-series of international standards on styrene-acrylonitrile (SAN) moulding and extrusion materials which covers its Preparation of test specimens and determination of properties.
ISO 19064-2 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of styrene-acrylonitrile (SAN) moulding and extrusion materials.
ISO 19064-2 gives the requirements for handling the test material and for conditioning both the test material before moulding and the specimens before testing.
ISO 19064-2 gives procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made and lists properties and test methods that are suitable and necessary to characterize SAN moulding and extrusion materials.
The methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified in ISO 19064-2 are used in order to obtain reproducible and comparable test results. Values determined are not always identical to those obtained using specimens of different dimensions or prepared using different procedures.
Who is ISO 19064-2 for?
ISO 19064-2 on SAN moulding and extrusion materials is relevant to:
- Manufacturers of SAN moulding and extrusion materials
- Plastic industry
- Chemical engineers
- Manufacturers of electronic appliances, medical applications, and certain automotive applications.
Why should you use ISO 19064-2?
Styrene-acrylonitrile (SAN) is a rigid, transparent plastic produced by the copolymerization of styrene and acrylonitrile.
ISO 19064‑2 provides the general requirement on the preparation of test specimens either injection moulding or compression moulding of SAN moulding and extrusion materials and also gives information on the treatment and conditioning of test specimens.
ISO 19064‑2 provides general properties and test conditions and additional properties and test conditions of particular utility to SAN moulding and extrusion materials.
Overall, ISO 19064‑2 allows you to produce SAN moulding and extrusion materials to ensure rigidity, strength, toughness and transparency of the material specifying the methods and conditions of test to be used for the acquisition and presentation of data to ensure valid comparisons between SAN materials.
