Comprehensive compliance solutions for gas appliances

Gas appliance manufacturers must maintain quality while reducing cost and time to market. Standards and regulations evolve quickly, and noncompliance can result in delays, product recalls and potential safety risks.

Meeting consumers’ demands for appliance features, such as integrated electric and gas, can complicate compliance challenges, requiring multiple vendors’ services.

UL can help. We offer a wide array of advisory, testing and certification services for combustion appliances and components such as:

  • Barbecues
  • Food service equipment
  • Gas heaters
  • Household/domestic cooking

Gas Appliances Regulation (GAR)

The GAR is full harmonization legislation that clarifies the requirements each gas appliance and fitting has to fulfill and introduces harmonized content for the communication of gas supply conditions in EU countries, enabling the design and construction of safer and correctly performing products.

The Regulation covers:

  • Appliances burning gaseous fuel and fittings
  • New or secondhand appliances imported from a country outside of the EU
  • All forms of supply, including distance sales

As a manufacturer or importer, you have to show and declare compliance with the GAR through an EC type-examination certificate and a demonstrably valid product(ion) surveillance contract as part of the technical construction file.
