Direct-acting room heaters

WHICH IS THE BEST WAY TO VERIFY AND

CERTIFY OUR PRODUCT'S PERFORMANCE?

WHAT IS IT?

IT IS A THIRD PART APPROVAL ISSUED BY THE FRENCH

NATIONAL CERTIFICATION BODY "LCIE"

WHY IS IT IMPORTANT?

BECAUSE FRANCE REPRESENTS THE REFERENCE MARKET FOR ELECTRIC HEATING AND LCIE

HAS DEVELOPED INTERESTING AND OBJECTIVE METHODS TO CHECK HEATING PRODUCTS

PERFORMANCE.

WHICH ARE REFERENCE STANDARDS?

APPLICABLE STANDARDS ARE:

• EN60335-1 "Hosehold and similar electric appliances - Safety General Requirements"

• EN60335-2-30 "Particular requirements for room heaters"

• EN 60335-2-43: "Particular requirements for clothes dryers and towel rails"

• EN60675:"Household electric direct-acting room heaters: Methods for measuring performance"

• LCIE 103-13 "Cahier des charges de la marque NF Electricitè Performance"

2.3 - SURFACE TEMPERATURETEST CONDITIONS

• THE PRODUCT IS RUN AT NOMINAL POWER INSIDE THE TEST ROOM.

• THE THERMOSTAT IS SET TO MAINTAIN A TEMPERATURE OF ABOUT 20±2°C

• A COLD AIR FLOW INSIDE THE TEST ROOM IS MODULATED SO THAT THE POWER CONSUMPTION NECESSARY TO MAINTAIN SET ROOM TEMPERATURE IS ABOUT:

• 20% OF MAXIMUM NOMINAL POWER TO SIMULATE REDUCED HEATING NEEDS

• 80% OF MAXIMUM NOMINAL POWER TO SIMULATE RELEVANT HEATING NEEDS

PRODUCT FUNCTIONING CHARACTERISTICS SHOULD BE THE SAME BOTH IN CASE OF HEAVY OR LIGHT HEATING

NECESSITY.
