Full title and description

STB BS EN ISO 180:2023 — Plastics. Determination of Izod impact strength. This document is the British (BS EN) adoption of ISO 180:2023 and specifies the standardized Izod pendulum impact test method for plastics to determine impact strength and to assess relative brittleness or toughness of materials under defined conditions.

Abstract

This standard specifies procedures, specimen types and notch configurations, apparatus requirements and reporting rules for measuring the Izod impact strength of plastics. It describes test conditions and parameters for different specimen types, and it is intended for comparative testing, quality control and materials characterization to estimate brittleness or toughness within the limits of the test method.

Scope

The standard specifies a method for determining the Izod impact strength of plastics under defined conditions. It covers preparation and dimensions of test specimens (including notched and unnotched types), apparatus and striker/pendulum specifications, test temperatures and conditioning, details on test execution, calculation and reporting of impact strength, and relevant tolerances. The method is intended for comparative testing, quality control and research rather than as a direct predictor of in-service performance.

Key topics and requirements

• Definition of Izod test configuration (pendulum striker, specimen clamping orientation, notch geometry).
• Specified specimen types and dimensions for notched and unnotched tests.
• Conditioning procedures and test temperature requirements.
• Apparatus calibration, pendulum energy selection, and verification checks.
• Calculation of impact strength (energy absorbed normalized by specimen notch area) and reporting format.
• Test tolerances, repeatability considerations and guidance on interpreting results for comparative purposes.

Typical use and users

Used by materials testing laboratories, polymer manufacturers, product designers, quality/production control teams, research & development groups and conformity assessment bodies to characterize impact performance of plastic materials and to compare grades or formulations during development and QC.

Related standards

Commonly referenced alongside ISO 179 (Charpy impact tests), ISO 527 (tensile properties of plastics), ISO 8256 (tensile-impact properties) and comparable national/international methods such as ASTM D256 (Izod) and other ISO mechanical-test series for plastics. These related standards provide complementary impact or mechanical-property test methods and reporting practices used together for material characterization.
