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.

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 iso 1133 2005 not always correlate with their behaviour during processing. If such additional properties are required, they can be determined according to the test methods specified in ISOif suitable.

It gives the requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing. Subtotal: USD. It is not intended to conflict with, but to supplement, existing trade names and trademarks. This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyamide moulding and extrusion materials. The piston shall be manufactured from a material resistant to wear and corrosion up to the maximum temperature of the heating system and its properties and dimensions shall not be affected by the material being tested. 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. Every care has been taken to ensure that the file is suitable for use by ISO member bodies. One is a mass-measurement method. A stud may be added at the top of the piston to support a removable weight, but the piston shall be thermally insulated from the weight. Drafting Committee. It is applicable to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers. Complete Document. In addition, the clarity of the text has been improved. All Rights Reserved.

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.

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. Both methods are used primarily in quality control. For dated references, only the edition cited applies. All Rights Reserved. Currency display settings. For each material, the required moulding temperature and cooling methods are given in the appropriate International Standard for the material or as agreed between the interested parties. The test conditions normally used for thermoplastics are listed in Annex A. This May Also Interest You. 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. Procedure A is a mass-measurement method. This document defines a method of specifying delivery conditions for polyethylene PE recyclates. Standards Store by Accuris. Store Standards catalogue ICS 83
