EU Regulation 2016/426 is the Gas Appliances Regulation (GAR), which replaced the previous Gas Appliances Directive (GAD) 2009/142/EC. The regulation sets out requirements for the design, manufacture, and placing on the market of gas appliances and fittings intended for use within the European Economic Area (EEA). The GAR aims to ensure a high level of safety for gas appliances, protect consumers and the environment, and facilitate the free movement of gas appliances within the EU market.
Here's an overview of the certification process for compliance with EU Regulation 2016/426 (GAR):
Directive 2014/34/EU, commonly referred to as the ATEX Directive, is a European Union directive that sets out requirements for equipment and protective systems intended for use in potentially explosive atmospheres. The directive aims to ensure a high level of protection for workers and the public by preventing explosions and minimizing the risks associated with hazardous environments.
Here's an overview of the certification process for compliance with Directive 2014/34/EU:

Determine whether the product falls within the scope of the Gas Appliances Regulation. The regulation applies to gas appliances and fittings designed for use with specific types of gas (natural gas, liquefied petroleum gas, etc.), including boilers, heaters, ovens, cookers, and other gas-powered devices.
Identify the essential safety requirements set out in Annex II of Regulation 2016/426 that are applicable to the gas appliance or fitting. These requirements cover factors such as design, construction, materials, performance, and marking of gas appliances to ensure their safe operation.
Conduct a risk assessment to identify and evaluate potential hazards associated with the gas appliance or fitting throughout its lifecycle. This includes assessing risks related to gas leaks, combustion, overheating, pressure, and other safety aspects.
Design and manufacture the gas appliance or fitting in accordance with the essential requirements of the Gas Appliances Regulation. This may involve following harmonized standards, technical specifications, or other recognized methods of compliance.
Compile technical documentation demonstrating compliance with Regulation 2016/426. This documentation should include information about the design, construction, materials, testing, and performance of the gas appliance or fitting, as well as risk assessments and instructions for use.
Assess conformity with the requirements of the Gas Appliances Regulation through various conformity assessment procedures. This may include self-assessment based on internal production control, involvement of a notified body for assessment of full quality assurance, or type examination of individual products.
Affix the CE marking to the gas appliance or fitting once compliance with Regulation 2016/426 has been demonstrated. The CE marking indicates that the product meets the essential requirements of all applicable EU regulations, including the Gas Appliances Regulation.
Prepare a Declaration of Conformity stating that the gas appliance or fitting complies with the requirements of Regulation 2016/426. The Declaration of Conformity should be kept on file and made available to authorities upon request.
Authorities in EU member states conduct market surveillance activities to ensure that gas appliances and fittings placed on the market comply with the requirements of Regulation 2016/426. This may include inspections, testing, and enforcement actions to address non-compliant products.
Compliance with EU Regulation 2016/426 (GAR) is essential for manufacturers seeking to market gas appliances and fittings within the European Union.
