Status : Withdrawn. 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. In such cases, the use of the viscosity number in dilute solution, determined in accordance with the relevant part of ISO , is recommended for characterization purposes. Verfahren A dient zum Bestimmen der Masse. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December , and conflicting national standards shall be withdrawn at the latest by December

The thermoplastic material, which is contained in a vertical cylinder, is extruded through a die by a piston loaded with a known weight. This document 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. It is not intended to conflict with, but to supplement, existing trade names and trademarks. This document is also possibly applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena such as hydrolysis chain scission , condensation and cross-linking, but only if the effect is limited in extent and only if the repeatability and reproducibility are within an acceptable range. Full report circulated: decision for new DIS ballot. Both methods are used primarily in quality control. NOTE This is to avoid excessive friction caused by the piston leaning to one side or bending under heavy loads. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. The base of the cylinder 2 shall be thermally insulated in such a way that the area of exposed metal is less than 4 cm , and it is recommended that an insulating material such as Al O , ceramic fibre or another suitable material be used in 2 3 order to avoid sticking of the extrudate. The piston may be either hollow or solid. This document is applicable without prejudice to any existing legislation. General information.

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 flat surfaces of the die shall be checked to ensure that the area around the bore is not chipped. AWS D1. A dummy piston with a spirit level on its upper end is also a suitable means of checking conformity with this requirement. Compare with a ca The cylinder shall be manufactured from a material resistant to wear and corrosion up to the maximum temperature of the heating system, and the finish, properties and dimensions of its surface shall not be affected by the material being tested. Procedure A is a mass-measurement method. NOTE Excessive wear of the cylinder, piston head, and piston is an indication of misalignment of the piston. The test conditions normally used for thermoplastics are listed in annexes. It specifies symbols and abbreviated terms used to identify thermoplastic elastomers in industry, commerce, and government.
