Overview

EN 1458-1:2011 (EN 1458-1:2011) is the European safety standard for domestic direct gas-fired tumble dryers of types B22D and B23D with a nominal heat input not exceeding 6 kW. Published by SIST/CEN, Part 1 addresses safety requirements and type testing for construction, operation, marking and testing of these laundry appliances. The standard covers domestic units only and is focused on type testing rather than in‑service inspection or installation.

The standard does not apply to:

• catalytic combustion appliances;
• appliances designed exclusively for industrial use;
• appliances for corrosive or explosive atmospheres;
• condensing-type dryers (where combustion products are re‑dehumidified);
• appliances intended for use in vehicles, ships or aircraft.

Key Topics and Technical Requirements

EN 1458-1:2011 defines a comprehensive set of technical requirements and test methods including:

• Classification (gas type, evacuation of combustion products/supply of combustion air)
• Construction and design: materials, conversion to different gases, screws, maintenance, thermal insulation, gas connections and gas circuit soundness
• Supply of combustion air and evacuation and lint collection provisions
• Ignition and burners: ignition devices, ignition burners, main-burner establishment, burner construction and resistance to overheating
• Control and safety devices: automatic shut-off valves, multifunctional controls, flame supervision devices, regulators, preset gas rate adjusters and automatic burner control systems
• Thermostats and overheat cut-off devices, clocks/timing devices and pressure test points
• Mechanical hazards and stability - including specific provisions for appliances with an opening dimension >200 mm and drum volume >60 dm3
• Operational safety and type testing: test gases, test room conditions, heat inputs (nominal and reduced), flame stability, combustion tests, limiting temperatures of components, floor and surrounding surfaces, motor temperatures, sooting
• Flame supervision and regulator tests to verify safety under normal, severe and abnormal conditions

Practical Applications

This standard is used to:

• Guide product design and development for domestic gas tumble dryers (B22D/B23D)
• Define type testing programs for safety certification and CE marking preparation
• Provide test methods for laboratories performing conformity and type tests
• Inform safety engineers, compliance officers and manufacturers about required safety features, temperature limits, combustion behaviour and mechanical protections

Who should use this standard

• Appliance manufacturers and designers
• Test laboratories and notified bodies performing type testing
• Compliance, risk and quality assurance teams
• Regulators and standards committees in the laundry appliance sector
