BS 5944-5:1985

Overview

BS 5944-5:1985 provides a simplified method for measuring airborne noise emitted by hydraulic fluid power systems and components, specifically focusing on pumps. This standard is essential for manufacturers and users of hydraulic systems who need to assess and manage the noise levels produced by their equipment. The standard outlines procedures for determining sound power levels in an anechoic chamber, ensuring accurate and reliable measurements.

Key Requirements

The standard specifies the following key requirements for the measurement process:

• Anechoic Chamber: The measurements must be conducted in a controlled environment, specifically an anechoic chamber, to eliminate reflections and external noise interference.
• Measurement Equipment: The standard outlines the necessary equipment and calibration procedures to ensure accurate sound level readings.
• Test Procedure: Detailed instructions on the positioning of the pump, microphone placement, and measurement techniques are provided to ensure consistency and reliability in results.
• Data Analysis: Guidelines for analysing the collected data and reporting sound power levels are included, ensuring compliance with the standard.

Implementation Benefits

Implementing BS 5944-5:1985 offers several benefits for organisations involved in the design, manufacture, and use of hydraulic systems:

• Noise Control: By following the standard, companies can effectively measure and control noise emissions, leading to quieter operations and improved workplace environments.
• Product Development: The standard aids in the development of quieter hydraulic systems, enhancing product competitiveness and customer satisfaction.
• Regulatory Compliance: Adhering to BS 5944-5:1985 supports compliance with local and international noise regulations, reducing the risk of legal issues and penalties.
• Market Access: Compliance with this standard can facilitate access to markets that require stringent noise control measures, broadening business opportunities.

Compliance Value

Compliance with BS 5944-5:1985 is crucial for organisations aiming to meet industry standards and regulations regarding noise emissions. The standard provides a clear framework for measuring sound power levels, which can be critical in:

• Environmental Impact Assessments: Accurate noise measurements are essential for evaluating the environmental impact of hydraulic systems.
• Health and Safety Regulations: Meeting noise level requirements helps protect workers from potential hearing damage and contributes to a safer workplace.
• Quality Assurance: Adhering to this standard enhances the quality assurance processes within organisations, ensuring that products meet customer expectations and regulatory demands.

In summary, BS 5944-5:1985 is a vital standard for the measurement of airborne noise from hydraulic fluid power systems. Its implementation not only aids in compliance with noise regulations but also enhances product development and workplace safety.
