Overview

SIST ISO 4412-2:1998 specifies a standardized test code for determining the airborne noise levels of hydraulic fluid power motors. Developed by the Slovenian Institute for Standardization (SIST) and based on the international ISO 2204 framework, this standard establishes procedures to measure and report the sound power levels of hydraulic motors under controlled installation and operating conditions. The purpose is to provide consistent, repeatable results that enable comparison between different types and designs of fluid power motors, regardless of size, as long as they are operated under steady-state conditions and at speeds exceeding 50 rpm.

Key Topics

Scope: Applies to all types of hydraulic fluid power motors, with specific guidelines for test methods and reporting.

Test Environment: Requires controlled test environments that meet free-field or reverberant criteria per ISO 3744 and ISO 3745.

Noise Measurement: Focuses exclusively on airborne noise radiated directly from the motor, excluding background and structure-borne noise.

Instrumentation: Specifies use of calibrated, standard-compliant acoustical and hydraulic instrumentation to ensure accuracy and repeatability.

Operating Conditions: Defines stable parameters for operating pressure, speed, temperature, and torque to maintain consistency during tests.

Measurement Procedures: Outlines correct placement and number of sound measurement points and provides background noise correction guidelines.

Reporting: Standardizes the acoustic information and motor-specific details to be recorded and included in the test report for full transparency and compliance.

Application Guidance: Additional guidelines for practical application are available in annex C for users conducting real-world assessments.

Applications

Design Verification: Manufacturers can use this standard to evaluate and optimize the acoustic performance of hydraulic motors during development and production.

Quality Control: It serves as a reliable benchmark for consistent product testing and quality assurance in the fluid power industry.

Compliance and Certification: Organizations can demonstrate adherence to international noise emission requirements, a critical factor in workplace safety and environmental regulations.

Product Comparison: Facilitates fair comparison of airborne noise levels between different hydraulic motors, allowing end-users and buyers to make informed decisions based on standardized data.

System Integration: Engineering teams can use measured airborne noise data to minimize noise pollution in hydraulic systems, supporting quieter and more efficient operations in industrial environments.

Environmental Assessment: Supports compliance with occupational health and noise abatement directives by quantifying and controlling acoustic emissions at the source.
