ISO specifies two procedures for the determination of the melt mass-flow rate MFR and the melt volume-flow rate MVR of thermoplastic materials under specified conditions of temperature and load. One is a mass-measurement method. The other is a displacement-measurement method. Normally, the test conditions for measurement of melt flow rate are specified in the material standard with a reference to ISO The test conditions normally used for thermoplastics are listed in annexes. These methods are in principle also applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena such as hydrolysis, condensation or crosslinking, but only if the effect is limited in extent and only if the repeatability and reproducibility are within an acceptable range. For materials which show significantly affected rheological behaviour during testing, these methods are not appropriate.

No spacer shall be used with this die to increase the apparent length to 8,00 mm. Customer care. Life cycle Previously Withdrawn. This May Also Interest You. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. The MFR can be determined from MVR measurements, or vice versa, provided the melt density at the test temperature is known. Plastics - Poly vinyl chloride - Determination of residual vinyl chloride monomer using gas-chromatographic method ISO It is not intended to conflict with, but to supplement, existing trade names and trademarks. Detail Summary. This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. In tests with very low loads, the piston may need to be hollow, otherwise it may not be possible to obtain the lowest prescribed load. For materials which show significantly affected rheological behaviour during testing, these methods are not appropriate. NOTE The rates of shear in these methods are much smaller than those used under normal conditions of processing, and therefore it is possible that data obtained by these methods for various thermoplastics will not always correlate with their behaviour during processing.

Method C is a version of method B, for which a die with half the height and half the diameter is used. First, these materials must be sufficiently dried and must be dry when poured into the extrusion barrel.

The method is based on sample dissolution and headspace gas chromatography. Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing. Featured Products. NOTE The rates of shear in these methods are much smaller than those used under normal conditions of processing, and therefore it is possible that data obtained by these methods for various thermoplastics will not always correlate with their behaviour during processing. The thermoplastic material, which is contained in a vertical cylinder, is extruded through a die by a piston loaded with a known weight. NOTE This is to avoid excessive friction caused by the piston leaning to one side or bending under heavy loads. Alternatively, a mechanical loading device combined with, for example, a load cell, providing the same level of accuracy as the removable weights, may be used. Superseded By:.
