Full title and description

ISO 10726:2020 — Portable chain-saws — Chain catcher — Dimensions and mechanical strength. This International Standard specifies required dimensions and mechanical-strength criteria for the chain catcher fitted to portable chain‑saws and defines the corresponding test method to verify compliance.

Abstract

The document sets out dimensional requirements, mechanical strength requirements and an associated test method for the chain catcher used on portable chain‑saws, intended to reduce hazards from a broken or derailed saw chain. It replaces the earlier 1992 edition and is published as Edition 2 (2020).

General information

• Status: Published (confirmed international standard).
• Publication date: May 2020 (edition published 15 May 2020).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.060.80 (Machinery for forestry; portable chain‑saws).
• Edition / version: Edition 2 (2020).
• Number of pages: 3 (core ISO text; national/BS/retail publications sometimes show additional front/back matter and different pagination).

Scope

ISO 10726:2020 specifies the dimensional and mechanical strength requirements for the chain catcher fitted to portable chain‑saws and describes the test procedure to verify these requirements. The standard applies to the chain catcher component of portable chain‑saws (hand‑held machines) and is intended to support safety and conformity assessment activities in design, production and testing.

Key topics and requirements

• Definition of required chain‑catcher geometry and critical dimensions.
• Mechanical strength criteria for the chain catcher to withstand chain derailment and partial breakage events.
• Prescribed laboratory test method(s) to demonstrate conformity with strength and dimensional requirements.
• Reference to applicability for portable, hand‑held chain‑saws and replacement of the 1992 edition.

Typical use and users

Manufacturers and designers of portable chain‑saws, product safety engineers, test laboratories, conformity assessment bodies, and regulators or standards committees concerned with operator safety and machine design use this standard to specify, test and verify chain‑catcher performance as part of overall chainsaw safety measures.

Related standards

ISO 10726:2020 is part of the body of forestry machinery standards overseen by ISO/TC 23/SC 17. It is related to broader chainsaw safety standards such as ISO 11681‑1 (Portable chain‑saw safety requirements and testing — Part 1: chain‑saws for forest service) and ISO 11681‑2 (Part 2: chain‑saws for tree service), which cover machine safety requirements, tests and user information. The 1992 edition of ISO 10726 was replaced by the 2020 edition.

FAQ

Q: What is this standard?

A: ISO 10726:2020 specifies dimensional and mechanical strength requirements and the test method for the chain catcher fitted to portable chain‑saws.

Q: What does it cover?

A: It covers the required geometry and strength characteristics of the chain‑catcher component and describes the test procedure to verify that the component meets those requirements; it does not set out full machine safety requirements (those are covered in related standards such as ISO 11681 series).

Q: Who typically uses it?

A: Chainsaw manufacturers and designers, test laboratories, conformity assessment bodies, safety engineers, and regulators use the standard when designing, testing or certifying chain‑catcher performance.

Q: Is it current or superseded?

A: ISO 10726:2020 is the current edition (Edition 2, 2020). The ISO record shows the 2020 edition as the active edition and indicates the previous 1992 edition was replaced. National or retail copies may include additional front matter, but the ISO text published in May 2020 is the authoritative edition.

Q: Is it part of a series?

A: It belongs to the set of standards for portable chain‑saws and forestry machinery under ISO/TC 23/SC 17; it complements the ISO 11681 series (machine safety and testing for chain‑saws) though ISO 10726 is focused specifically on the chain‑catcher component.

Q: What are the key keywords?

A: Portable chain‑saw, chain catcher, dimensions, mechanical strength, test method, chainsaw safety, ISO 10726.
