NF EN ISO 17855-2, T50-006-2 (11/2024)

ISO 17855-2:2016 specifies the methods for preparing specimens and the testing methods to be implemented in order to determine the properties of PE for molding and extrusion. It indicates the requirements required when handling the test material, as well as when conditioning said material before molding and the specimens before testing. It specifies the procedures and conditions necessary for the preparation of the test pieces, as well as the procedures for measuring the properties of the materials from which these test pieces are manufactured. It also lists the properties and test methods appropriate and necessary for the characterization of PEs for molding and extrusion. The properties have been chosen from the general test methods given in ISO 10350-1. Other test methods of particular importance or widely used for these molding and extrusion materials are also included in this part of ISO 17855, as well as in the designation properties of ISO 17855-1. To obtain reproducible and comparable test results, it is necessary to use the preparation and packaging methods, as well as the specimen dimensions and test procedures specified below. The values thus determined will not necessarily be identical to those obtained using test pieces of different dimensions or prepared according to different operating procedures.
