Status : Withdrawn.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.

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.

This document establishes a nomenclature system for thermoplastic elastomers based on the chemical composition of the polymer or polymers involved.

Subtotal: USD. It is intended to support parties involved in the use of polyethylene PE recyclates obtained by mechanical recycling to agree on specifications for specific and generic applications. 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. This document does not apply to the following materials: — monomer casting-type polyamides of PA 6; — monomer casting-type polyamides of PA The methods specified are applicable only to thermoplastics, for which they give a measure of the temperature at which the thermoplastics start to soften rapidly. Drawing and Drafting. Along the piston stem, two thin annular reference marks shall be scribed 30 mm apart and so positioned that the upper one is aligned with the top of the cylinder when the distance between the lower edge of the piston head and the top of the die is 20 mm. Complementary Documents and Links:. Life cycle Previously Withdrawn.

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.

It specifies symbols and abbreviated terms used to identify thermoplastic elastomers in industry, commerce, and government. NOTE In order to obtain mouldings in a reproducible state, the main steps of the procedure, including eight different cooling methods, are standardized. It is applicable to unmodified materials ready for normal use and materials modified, for example, by colorants, additives, fillers, reinforcing materials, and polymer modifiers. New Releases. The method is based on sample dissolution and headspace gas chromatography. One is a mass-measurement method. 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. Popular Standards Bundles. ISO shall not be held responsible for identifying any or all such patent rights. The pin gauge shall be sufficiently long to check the full length of the die using the go gauge. A dummy piston with a spirit level on its upper end is also a suitable means of checking conformity with this requirement. Technical Committee. Your shopping cart is empty. Price USD.
