Full title and description

St ISO 13772-2018 — ISO 13772:2018 — Forestry machinery — Portable chain-saws — Non-manually actuated chain brake performance. This International Standard specifies a test method to check the functioning and performance of the non‑manually actuated chain brake on electric- or gasoline‑engine, portable hand‑held chain‑saws.

Abstract

ISO 13772:2018 defines the procedure, test conditions and performance criteria for evaluating non‑manually actuated (automatic) chain brakes fitted to portable hand‑held chain‑saws, enabling repeatable assessment of brake activation and stopping performance for conformity testing and product development.

General information

• Status: Published (active international standard; amended).
• Publication date: February 2018 (ISO edition 4; published 2018-02).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.060.80 (Forestry equipment).
• Edition / version: Edition 4 (2018); amended by ISO 13772:2018/Amd 1:2020.
• Number of pages: 8 pages (core document).

Scope

This standard applies to portable, hand‑held chain‑saws used primarily in forestry and tree‑service and specifies a method to verify the operation and effectiveness of non‑manually actuated chain brakes (automatic chain‑brake systems). It covers test fixtures, test procedure, acceptance criteria and reporting requirements needed to assess whether the chain brake operates reliably under defined conditions. The document is intended for use in design verification, type testing and conformity assessment.

Key topics and requirements

• Definition and purpose of non‑manually actuated (automatic) chain brakes on portable chain‑saws.
• Test apparatus and setup required to simulate activation conditions and measure stopping performance.
• Specified test procedure steps, environmental and conditioning requirements, and instrumentation tolerances.
• Performance criteria and pass/fail rules for chain brake activation and stopping distance/time.
• Requirements for test reporting, documentation and traceability of test specimens.
• Recognition of the 2020 amendment which modifies or clarifies elements of the 2018 edition.

Typical use and users

Manufacturers of portable chain‑saws (design, validation and quality), third‑party and in‑house test laboratories, conformity assessment bodies, product safety regulators, procurement teams specifying safety requirements, and R&D groups working on chain‑saw safety systems use this standard to verify automatic chain brake performance and to support certification and compliance activities.

Related standards

ISO 13772 is part of the ISO/TC 23/SC 17 family of standards covering portable chain‑saws and forestry machinery. Closely related standards include tests and safety requirements for portable chain‑saws and components such as ISO 11681‑1 (safety requirements and testing for chain‑saws), ISO 10726 (chain catcher dimensions and strength), and ISO 7915 (handle strength), which together address complementary safety, dimensional and strength requirements for chain‑saws and subcomponents.

FAQ

Q: What is this standard?

A: ISO 13772:2018 is an international standard that specifies a repeatable test method for assessing the performance of non‑manually actuated (automatic) chain brakes fitted to portable hand‑held chain‑saws.

Q: What does it cover?

A: It covers the test setup, procedure, measurement and acceptance criteria needed to determine whether an automatic chain brake activates and stops the saw chain within defined performance limits under specified conditions. The 2018 edition was later modified by an amendment published in 2020.

Q: Who typically uses it?

A: Chain‑saw manufacturers, testing laboratories, certification and conformity bodies, safety regulators, and procurement/specification teams use the standard for product verification, compliance testing and safety validation.

Q: Is it current or superseded?

A: ISO 13772:2018 is the current published edition (2018) and has an amendment ISO 13772:2018/Amd 1:2020. It replaced the 2009 edition. Users should check national adoption or later revisions, but as published the 2018 edition with the 2020 amendment is the applicable text.

Q: Is it part of a series?

A: Yes. It belongs to the body of standards for portable chain‑saws and forestry machinery maintained by ISO/TC 23/SC 17. Other related ISO documents address overall safety requirements, component strength and dimensional requirements (for example ISO 11681‑1, ISO 10726 and ISO 7915).

Q: What are the key keywords?

A: Chain brake, non‑manually actuated, automatic chain brake, portable chain‑saw, forestry machinery, test method, performance, ISO 13772:2018, amendment 2020.
