ISO 23552-1:2007/Amd 1:2010

Overview

ISO 23552-1:2007/Amd 1:2010 is an amendment to the international standard addressing safety and control devices for gas and/or oil burners and appliances. Specifically, it focuses on electronic fuel/air ratio controls that ensure optimal combustion performance and safety. This amendment introduces additional regional requirements specific to Japan, reflecting local regulatory practices and safety needs.

Developed by ISO Technical Committee ISO/TC 161, this standard provides guidelines and requirements to enhance the reliability, safety, and control accuracy of electronic fuel/air ratio control systems used in household and commercial gas and oil burner appliances. Importantly, it excludes applications in industrial thermo-processes and incineration, emphasizing its scope within the safety-critical residential and commercial sectors.

Key Topics

• Fuel/Air Ratio Controls: Defines the design and safety requirements for electronic devices that regulate the correct ratio of fuel to air, crucial for efficient combustion and emissions control.
• Safety Standards: Ensures devices prevent unsafe operating conditions that could lead to combustion failures or hazardous emissions.
• Electronic Type Controls: Covers specific electronic control components, enhancing precision in managing combustion processes.
• Regional Additions for Japan: Integrates local regulations, emphasizing compliance with Japan’s specific safety and environmental standards.
• Scope Limitation: Clarifies that this amendment does not apply to electronic fuel/air controls in industrial thermo-process and incineration applications.
• Technical Committee ISO/TC 161: Governs the standardization process, reflecting expertise in control and protective devices for gas and oil burners.

Applications

This standard is essential for manufacturers, designers, and installers of gas and oil-powered appliances incorporating electronic fuel/air ratio controls, including:

• Residential Heating Systems: Enhances safety and combustion efficiency in domestic boilers, furnaces, and water heaters.
• Commercial and Light Industrial Burners: Improves control accuracy for equipment used in commercial kitchens, laundries, and small-scale manufacturing.
• Gas and Oil Burners in Appliances: Applies to a wide range of heating appliances, ensuring consistent and safe fuel/air mixtures.
• Product Certification and Compliance: Assists certifying bodies in evaluating compliance with international and Japanese safety standards.
• Safety Audits and Risk Management: Supports safety assessments by providing benchmarks for acceptable electronic control device performance.

Related Standards

• ISO 23552 Series: Other parts focus on different types of safety and control devices for gas and oil burners.
• IEC Standards on Electrotechnical Safety: Complementary standards address the broader electrical safety requirements applicable to electronic controls.
• Regional Japanese Standards: Harmonizes with Japan-specific safety regulations and industrial guidelines.
• ISO/IEC Directives, Part 2: Governs the drafting and approval process of international standards, ensuring consistency and quality.
• Industrial Burner Standards: Separate standards cover industrial thermo-process and incineration applications not included in this amendment.

ISO 23552-1:2007/Amd 1:2010 is critical for advancing the safety, efficiency, and regulatory compliance of electronic fuel/air ratio controls in gas and oil appliances. By incorporating regional requirements for Japan, it promotes international consistency while respecting local legislation, making it a key reference for manufacturers and safety professionals globally.
