Iso 1133 2005

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.

The MVR will freemoviesfull.cc found particularly useful when comparing materials of different filler content and when comparing filled with unfilled thermoplastics. NOTE The rates of shear in these methods are much smaller than those used under normal conditions of processing, and therefore data obtained by these methods for various thermoplastics may not always correlate with their behaviour during processing, iso 1133 2005.

Means, Inc. It is not intended to imply that materials having the same designation give the same performance. Plastics - Compression moulding of test specimens of thermoplastic materials ISO 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. The MVR will be found particularly useful when comparing materials of different filler content and when comparing filled with unfilled thermoplastics. 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. A dummy piston with a spirit level on its upper end is also a suitable means of checking conformity with this requirement. 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.

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.

A sharp-edged spatula has been found suitable. In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. Read more… Read less…. For dated references, only the edition cited applies. This document specifies the general principles and the procedures to be followed with thermoplastics in the preparation of compression-moulded test specimens, and sheets from which test specimens can be machined or stamped. This document does not cover the characterization of plastics wastes see EN This document establishes a system of designation for polyamide PA moulding and extrusion materials, which can be used as the basis for specifications. Normally, the test conditions for measurement of melt flow rate are specified in the material standard with a reference to ISO Plastics - Poly vinyl chloride - Determination of residual vinyl chloride monomer using gas-chromatographic method ISO The MVR will be found particularly useful when comparing materials of different filler content and when comparing filled with unfilled thermoplastics. The main task of technical committees is to prepare International Standards.
