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: EN "Hosehold and similar electric appliances - Safety General Requirements" EN "Particular requirements for room heaters" EN : "Particular requirements for clothes dryers and towel rails" EN60675:"Household electric direct-acting room heaters: Methods for measuring performance" LCIE "Cahier des charges de la marque NF Electricitè Performance"

NF PERFORMANCE REQUIREMENTS 1 - ENVIRONMENT 2 - SAFETY & RELIABILITY PROTECTION AGAINST ELECTRIC AND THERMAL SHOCKS AIR OUTLET TEMPERATURE SURFACE TEMPERATURE HEATING ELEMENT(S) RELIABILITY 3 - PARTICULAR REQUIREMENTS

1 - ENVIRONMENT THE PRODUCT SHOULD NOT MAKE THE WALL DIRTY IN STEADY CONDITION AT NOMINAL POWER THE TEMPERATURE RISE OF THE SURFACE OVER THE HEATER SHOULD NOT BE OVER 20°C

2 - SAFETY & RELIABILITY PROTECTION AGAINST ELECTRIC AND THERMAL SHOCKS ACCESSIBILITY TESTS ARE MADE WITH PROBES DIFFERENT FROM THE ONES USED DURING SAFETY APPROVAL

2 - SAFETY & RELIABILITY AIR OUTLET TEMPERATURE AIR OUTLET GRID TEMPERATURE RISE: MAX 100°C

2 - SAFETY & RELIABILITY SURFACE TEMPERATURE TEST 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.  20%  80%

SURFACE TEMPERATURE DISPERSION DIFFERENCE BETWEEN TEMPERATURE MEASURED IN DIFFERENT POINTS BOTH AT 20% AND 80% SHOULD NOT EXCEED 30°C SURFACE TEMPERATURE STABILITY DIFFERENCE BETWEEN THE MAX TEMPERATURE MEASURED IN EVERY POINT BOTH AT 20% AND 80% SHOULD NOT EXCEED 15°C

2 - SAFETY & RELIABILITY HEATING ELEMENT(S) RELIABILITY T1=MAX TEMP OF THE 244V T2=0.75 T V TIME CYCLE IS SET TO MAINTAIN H.E. TEMP IN THE RANGE T1-T2

3 - PARTICULAR REQUIREMENS 3.1 ROOM TEMPERATURE DRIFT MAX 1,5°C 20% 80%

3 - PARTICULAR REQUIREMENS 3.2 ROOM TEMPERATURE AMPLITUDE MAX 0,5°C 20% 80%
