Описание (английский):

This document establishes requirements and test procedures for determining the performance of spark arrestor exhaust systems of multi position small engines used in portable applications, such as chain-saws, brush-cutters, grass-trimmers, pole-mounted pruners, edgers and similar shaft-drive machines, hedge trimmers and hand-held and back-pack blowers. It is not applicable to spark arrestors used in vehicles or stationary equipment.

Overview

ISO 9467:2023 - "Exhaust system for multi position small engine machines - Test procedures and performance requirements for spark arrestors" defines test methods and minimum performance criteria for spark arrestor-equipped exhaust systems used on multi-position small engine (MSE) machines. Typical applications covered include chain-saws, brush-cutters, grass-trimmers, pole-mounted pruners, edgers, hedge trimmers and hand‑held or backpack blowers. The standard updates and replaces the previous edition and expands scope to additional MSE types. It is not applicable to vehicle or stationary equipment spark arrestors.

Key topics and requirements

Scope and definitions: clear terms such as contact plane, exposed surface temperature, exhaust gas temperature, power unit and spark arrestor.

Performance requirements: minimum safety and maintenance expectations, including limits on exhaust gas and exhaust system surface temperatures, restrictions on debris accumulation and maximum screen opening sizes for screen-type arrestors.

Test procedures:

Screen test - verification of screen material, screen openings, housing seals and reassembly integrity.
Temperature tests - measurement methods for exposed surface temperature and exhaust gas temperature at defined contact planes and points where hot gases impinge.
Contact plane determination - procedures tailored for different MSE configurations (chain-saws, brush-cutters, hedge trimmers, blowers, etc.).

Test equipment and reporting: specifications for calibrated loading devices, tachometers, thermocouples, graduated cylinders and wire plug gauges; requirements for documenting test data and reports.

Marking, mounting and installation: identification and installation requirements to ensure correct application and maintenance of spark arrestors.

Practical applications and who uses it

ISO 9467:2023 is intended for:

Manufacturers and designers of portable forestry and landscaping equipment - to design compliant exhaust systems and select appropriate spark arrestors.

Test laboratories and certification bodies - to perform consistent, reproducible spark arrestor performance testing.

Regulatory and procurement teams - to specify safety requirements and ensure compliance in regions where spark arrestors are required.

Safety managers and maintenance personnel - to understand acceptable limits, inspection criteria and maintenance needs to reduce fire ignition risk during use.

Using ISO 9467 helps reduce fire ignition risks from MSE exhausts by standardizing how spark arrestors are evaluated, selected and installed.
