Adopted by Resolution No. 24 of the Institute of Standardization of the Republic of Moldova, dated 30.03.2026

This technical specification defines the requirements and test methods for determining the tensile strength of plastic materials, specifically focusing on single-point stress measurements under controlled conditions. It establishes the fundamental principles necessary for evaluating the mechanical integrity of polymer products used in various industrial applications. The document outlines the preparation of test specimens, the conditioning procedures required prior to testing, and the specific parameters for operating tensile testing machines. It details the calculation methods for deriving stress-strain relationships and provides guidance on interpreting the resulting data to assess material performance. This standard is designed to ensure consistency in laboratory testing across different facilities and supports the harmonization of quality control processes. It serves as a reference for manufacturers, suppliers, and regulatory bodies involved in the production and assessment of plastic goods. The specifications include provisions for handling different sample geometries and addressing potential sources of experimental error. By adhering to these protocols, stakeholders can achieve reliable and comparable results when characterizing the mechanical properties of plastics.
