Plastics - Preparation of test specimens by machining (ISO 2818:2018)
This document establishes the general principles and procedures to be followed when machining and notching test specimens from compression-moulded and injection-moulded plastics, extruded sheets, plates and partially finished or wholly finished products. In order to establish a basis for reproducible machining and notching conditions, the following general standardized conditions are applied. It is assumed, however, that the exact procedures used are selected or specified by the relevant material specification or by the standards on the particular test methods. If sufficiently detailed procedures are not thus specified, the interested parties agree upon the conditions to be used.
EN ISO 2818:2019 - Plastics: Preparation of test specimens by machining (ISO 2818:2018) establishes general principles and procedures for machining and notching test specimens from plastics. The standard applies to specimens taken from compression‑moulded and injection‑moulded parts, extruded sheets and plates, and partially or wholly finished products. It defines a common basis for reproducible machining conditions so that mechanical test results are comparable and representative.
EN ISO 2818:2019 is used wherever machined plastic specimens are required for mechanical testing:
