Overview

EN ISO 13802:2025 - "Plastics - Verification of pendulum impact‑testing machines - Charpy, Izod and tensile impact‑testing" (CEN adoption of ISO 13802:2025) specifies the frequency and methods for verifying pendulum‑type impact testers used for Charpy, Izod and tensile impact tests (referenced in ISO 179‑1, ISO 180 and ISO 8256). This third edition replaces EN ISO 13802:2015 and focuses on verification of geometrical and physical properties of machines across capacities and designs. Instrumented machines are covered only when their geometrical/physical properties match non‑instrumented machines; force/work verification for instrumented systems is excluded.

Key topics

• Scope & applicability: Pendulum impact‑testing machines for plastics (Charpy, Izod, tensile impact) and conditions for instrumented machines.
• Verification procedures: Methods for initial installation checks, after repair, after relocation, and periodic verification (see Clause 6).
• Machine components & geometry: Checks for pendulum length, impact length, potential energy, bearing play (axial/radial), free‑hanging position, specimen/striker contact and machine frame integrity.
• Energy indicating systems: Verification and acceptance criteria for analogue and digital scales, and error limits for indicated absorbed energy.
• Losses and corrections: Determination and allowable limits for friction, air resistance and bearing losses affecting energy measurements.
• Documentation: Requirements for a verification report and recommended verification frequency (Clause 7).
• Normative annexes: Design requirements for Charpy, Izod and tensile impact machines (Annexes A–C) and informative guidance for frame/pendulum mass ratio, deceleration, and gauge plates (Annexes D–F).

Applications

EN ISO 13802:2025 is practical for:

• Test laboratories performing plastics impact testing to ensure machine conformity and reliable results.
• Machine manufacturers validating machine geometry and providing reference planes and factory verification.
• Quality and metrology teams responsible for periodic calibration, installation checks, or post‑repair verification.
• Accreditation bodies and auditors assessing compliance with standardized verification practices. Typical use cases include commissioning a new pendulum tester, post‑repair validation, relocation checks, and routine laboratory quality assurance.

Related standards

• ISO 179‑1 (Charpy impact test for plastics)
• ISO 180 (Izod impact test for plastics)
• ISO 8256 (Tensile impact test for plastics) These standards define test methods; EN ISO 13802:2025 specifies how to verify the test machines used to perform them.
