Full title and description

STB BS ISO 18564-2016 — Machinery for forestry — Noise test code. This designation refers to the national publication (STB) of the British adoption of ISO 18564:2016 (published as BS ISO 18564:2016). The document defines a standardized test code for measuring and declaring noise emission values of self‑propelled forestry machinery.

Abstract

ISO 18564:2016 provides the information and procedures required to measure noise emission characteristics of self‑propelled forestry machinery under standardized conditions. It specifies methods to determine A‑weighted emission sound pressure levels at the operator's station and the A‑weighted sound power value for machine types such as fellers, bunchers, delimbers, forwarders, loaders, skidders, processors, harvesters, mulchers and multi‑function machines. The standard supports manufacturers, test laboratories and regulators in declaring and comparing noise emissions and in guiding noise‑control design.

Scope

This standard applies to self‑propelled forestry machines and sets out a repeatable test code for determining overall noise emission values: the A‑weighted operator station sound pressure level and the A‑weighted sound power level of the machine. It covers test conditions, measurement positions, instrumentation and reporting necessary to declare noise emission values for the purposes of manufacturer declaration, family comparisons and source‑level noise control during design. It does not replace more detailed frequency‑band analysis standards when those are required for low‑noise design.

Key topics and requirements

• Definition of applicable machine types (fellers, bunchers, delimbers, forwarders, loaders, skidders, processors, harvesters, mulchers, multi‑function machines).
• Procedures to measure A‑weighted sound pressure at the operator’s station under specified operating conditions.
• Method to determine A‑weighted sound power level of the machine for declaration purposes.
• Specification of test conditions, load cases and measurement positions to ensure repeatability and comparability.
• Instrumentation, calibration and environmental condition requirements for valid measurements.
• Guidance to manufacturers on declaring noise emissions and comparing machines within a family.
• Reference to frequency‑band measurement methods (e.g., ISO 3744, ISO 11201) when banded data are needed for low‑noise design.

Typical use and users

Primary users are forestry equipment manufacturers, acoustic test laboratories, certification bodies and regulatory authorities concerned with occupational and environmental noise. Designers and R&D engineers use the standard during development to reduce machine noise at source. Procurement specialists and fleet managers may use declared values for machine selection and environmental compliance.

Related standards

Commonly referenced standards include ISO 6814 (terminology and definitions for forestry machinery), ISO 3744 (sound power determination by sound pressure — engineering method), ISO 11201 (measurement of sound pressure level in the presence of reflecting surfaces), and other ISO/BS standards on noise declaration and measurement practice. National workplace and environmental noise regulations may also prescribe or reference this test code for forestry machinery.

FAQ

Q: What is this standard?

A: STB BS ISO 18564-2016 is the national publication label for the British adoption of ISO 18564:2016, titled "Machinery for forestry — Noise test code." It prescribes standardized methods to measure and declare noise emissions from self‑propelled forestry machines.

Q: What does it cover?

A: It covers test procedures, measurement positions, operating conditions and reporting required to determine A‑weighted emission sound pressure at the operator's station and the A‑weighted sound power of forestry machines for manufacturer declaration, comparison and design purposes.

Q: Who typically uses it?

A: Manufacturers of forestry machinery, acoustic test laboratories, product certification bodies, regulatory agencies, design engineers and procurement/fleet managers who need standardized, comparable noise emission data.

Q: Is it current or superseded?

A: The standard was published in 2016. The ISO edition (ISO 18564:2016) was subsequently reviewed and confirmed; users should check the national standards body (publisher) for the current status in their country and for any amendments or later revisions.

Q: Is it part of a series?

A: It sits within ISO work on machinery acoustics and forestry equipment. It is commonly used alongside related standards such as ISO 6814 (forestry machinery definitions), ISO 3744 and ISO 11201 (sound power/sound pressure measurement methods) and other ISO/BS standards on noise declaration and measurement practice.
