Full title and description

ISO 7914:2023 — Forestry machinery — Portable chain-saws — Minimum handle clearance and sizes. This International Standard specifies required clearances and related dimensional requirements for the front and rear handles of portable, hand‑held chain‑saws to promote safe, ergonomic operation and to support conformity assessment.

Abstract

This document specifies the minimum clearances and related dimensions for the front and rear handles of portable, hand‑held chain‑saws. It replaces earlier editions and amendments to provide an up‑to‑date set of dimensional requirements for manufacturers, test houses and regulatory use.

Scope

ISO 7914:2023 applies to portable, hand‑held chain‑saws and specifies minimum handle clearance dimensions and related handle sizes for the front and rear handles. The requirements are intended to ensure safe and comfortable hand placement, reduce risk of interference with moving parts, and provide consistent measurement points for conformity testing and design verification. This edition supersedes the 2002 edition and its amendments.

Key topics and requirements

• Minimum clearances between handles and saw body/components for front and rear handles.
• Dimensional specification of handle sizes and grip envelopes to support ergonomic use.
• Defined measurement points, reference planes and test arrangements for verifying clearances.
• Figures/illustrations showing handle locations and how dimensions are taken.
• Normative references and relationship to other chain‑saw safety standards (for example, standards that set overall safety and testing requirements).

Typical use and users

Primary users include chain‑saw manufacturers and designers (for product design and verification), test laboratories and conformity assessment bodies (for dimensional checks), procurement/specification engineers (to reference minimum handle dimensions in contracts), standards committees, and regulatory or certification agencies responsible for forestry equipment safety.

Related standards

Closely related standards address overall chain‑saw safety, performance and testing, notably the ISO 11681 series (Machinery for forestry — Portable chain‑saw safety requirements and testing, Parts 1 and 2) and other ISO/TC 23/SC 17 outputs covering machine safety and test methods. ISO 7914 is intended to be used together with these functional safety standards where handle dimensions are relevant to safe operation.

FAQ

Q: What is this standard?

A: ISO 7914:2023 is the International Standard that defines minimum clearances and related dimensional requirements for the front and rear handles of portable, hand‑held chain‑saws.

Q: What does it cover?

A: It covers dimensional requirements and measurement methods for handle clearances and sizes (front and rear handles) to ensure safe and ergonomic hand placement and to provide consistent points for conformance testing.

Q: Who typically uses it?

A: Manufacturers, product designers, test laboratories, conformity assessment bodies, procurement/specification teams, safety regulators, and standards committees working with forestry machinery and hand‑held power tools.

Q: Is it current or superseded?

A: It is current — published in April 2023 (Edition 4) — and it supersedes earlier editions including ISO 7914:2002 and its amendments.

Q: Is it part of a series?

A: Not a numbered series under the same document number, but it is part of the family of forestry machinery and chain‑saw safety standards developed by ISO/TC 23/SC 17 and is commonly used together with the ISO 11681 series (safety requirements and testing for portable chain‑saws).
