Full title and description

St ISO 13802-2025 — Plastics — Verification of pendulum impact-testing machines — Charpy, Izod and tensile impact-testing. This International Standard specifies the frequency and methods for verifying pendulum-type impact-testing machines used to perform Charpy, Izod and tensile impact tests on plastics, and gives requirements for the geometrical and physical properties of the machines applicable during installation, relocation, repair and periodic checking.

Abstract

Specifies methods and intervals for verification of pendulum impact-testing machines (Charpy, Izod and tensile impact). Covers verification of geometrical and physical properties for both instrumented and non‑instrumented machines where those properties are equivalent; it does not cover force/work verification of instrumented machines. Intended for use when machines are installed, moved, repaired or undergo periodic checks.

General information

• Status: Published (International Standard).
• Publication date: August 2025 (national listings report 13 August 2025).
• Publisher: ISO — International Organization for Standardization.
• ICS / categories: 83.200 (Equipment for the rubber and plastics industries).
• Edition / version: Edition 3 (2025).
• Number of pages: 35 pages (ISO listing).

Scope

The standard applies to pendulum-type impact-testing machines of various capacities and designs used for Charpy, Izod and tensile impact tests (as referenced in ISO 179‑1, ISO 180 and ISO 8256). It lays down verification methods for the geometrical and physical properties of machine components and indicates when verifications should be performed (installation, after repair or relocation, and during routine checks). The document explicitly excludes force/work verification of instrumented machines.

Key topics and requirements

• Definitions and classification of pendulum impact-testing machines for Charpy, Izod and tensile impact tests.
• Required geometrical and physical properties of machine components to be verified (pendulum dimensions, striking edge geometry, anvil and support alignment, clamping and specimen supports).
• Verification methods and measurement procedures for those properties, including tolerances and acceptance criteria.
• Recommended verification frequency and triggers: initial installation, after repair, after relocation, and during periodic checks.
• Provisions for instrumented machines limited to geometrical/physical-property verification; force/work calibration of instrumented systems is outside the scope.
• References to the companion test standards for specimen preparation and test methods: ISO 179‑1, ISO 180 and ISO 8256.

Typical use and users

Used by materials testing laboratories, calibration and metrology bodies, plastics manufacturers and quality departments, test-house operators, machine manufacturers and service/repair organizations to ensure impact-testing machines provide reliable and reproducible results and meet ISO requirements for Charpy, Izod and tensile impact testing.

Related standards

Directly related to: ISO 179‑1 (determination of Charpy impact properties), ISO 180 (Izod impact test) and ISO 8256 (tensile impact). Supersedes ISO 13802:2015 (and earlier editions). Regional/adopted versions include EN/BS/DIN adoptions of ISO 13802:2025. Laboratories should also consider ISO/IEC 17025 when performing verifications and calibrations.

Q: What does it cover?

A: It covers verification of geometrical and physical properties of pendulum impact-testing machines and defines when verifications should be performed (installation, after repair/relocation, periodic checks). It does not cover force/work verification for instrumented machines.

Q: Who typically uses it?

A: Materials testing laboratories, manufacturers of plastics and impact-testing equipment, calibration and metrology services, conformity assessment bodies, and QA/test engineers in industry.

Q: Is it current or superseded?
