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. 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 does not provide engineering data, performance data, or data on processing conditions which can be required to specify a material.

It lists the properties and test methods that are suitable and necessary to characterize polyamide moulding and extrusion materials. Currency display settings. Subtotal: USD. 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. Superseded By:. To ensure satisfactory operation of the apparatus, the cylinder and the piston head shall be made of materials of different hardness. Adobe is a trademark of Adobe Systems Incorporated. Contact Us. For materials which show significantly affected rheological behaviour during testing, these methods are not appropriate. The thermocouple should be encased in a metallic sheath having a diameter of approximately 1,6 mm with its hot junction grounded to the end of the sheath. Quality Management. It is not intended to conflict with, but to supplement, existing trade names and trademarks. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. This document establishes a system of designation for polyamide PA moulding and extrusion materials, which can be used as the basis for specifications.

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. An optional nitrogen blanket at the extrusion barrel prevents direct contact by the material with the ambient air.

In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. It specifies symbols and abbreviated terms used to identify thermoplastic elastomers in industry, commerce, and government. The test conditions normally used for thermoplastics are listed in Annex A. 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. Create New Account. Procedure B is a displacement-measurement method. Two variants of the basic method are specified. If outside the tolerance limits, the die shall be discarded. Both methods are used primarily in quality control. Buy Standard.
