Overview
EN 61770:2009/A1:2019, issued by the European Committee for Electrotechnical Standardization (CENELEC), is a critical standard addressing the safety of electric appliances connected to water mains. This amendment to the original EN 61770:2009 standard focuses on preventing backsiphonage and mitigating failure risks in hose-sets used in such appliances.
Backsiphonage refers to the undesired reverse flow of water from appliances back into the potable water supply, which can cause contamination and pose serious health risks. Hose-set failure includes leaks or ruptures that can lead to water damage or appliance malfunction. EN 61770:2009/A1:2019 ensures that manufacturers and installers implement safety measures that protect consumers and maintain the integrity of water supply systems.
The standard aligns closely with the International Electrotechnical Commission's IEC 61770:2008/A1:2015, reflecting globally recognized best practices for electric appliances connected to water supplies.
Key Topics
Backsiphonage Avoidance: The standard specifies safety requirements and design considerations for electric appliances to prevent the reversal of water flow. This is essential to protect drinking water from contamination risks.
Hose-Set Safety: EN 61770:2009/A1:2019 provides updated requirements for hose-sets, including materials, construction, and durability specifications. Improvements in hose-set design reduce failures such as leaks or bursts.
Marking Requirements: For appliances connected only to cold water supplies, hose-sets supplied with the appliance do not need to be marked, simplifying compliance for certain types of equipment.
Compliance and Implementation Dates: The amendment was approved in 2019, with national adoption deadlines set to ensure consistent implementation across European countries.
Applications
This standard applies to a wide range of domestic and household electrical appliances connected to water mains, such as:
- Washing machines
- Dishwashers
- Water heaters
- Other appliances requiring a water supply connection
By establishing clear requirements for hose-sets and backflow prevention, EN 61770:2009/A1:2019 helps manufacturers design safer products, installers meet regulatory expectations, and consumers avoid health risks and property damage from water-related failures.
Related Standards
EN 61770:2009/A1:2019 is part of a broader regulatory landscape encompassing:
- IEC 61770:2008/A1:2015: The international standard on which the European version is based.
- Water Supply System Standards (ICS 91.140.60): Regulations governing water infrastructure safety and quality.
- General Domestic Electrical Appliance Standards (ICS 97.030): Overarching safety rules for household electrical devices.
Manufacturers and stakeholders should ensure compliance with this standard alongside related safety and performance standards to achieve end-to-end protection in appliances connected to water mains.
