BS EN 62693:2013

What is BS EN 62693 - Infrared electroheating installations about? 

BS EN 62693 is a European Standard that discusses industrial electroheating installations. The main objective of BS EN 62693 is to provide best industry practices that demonstrate the performance of infrared electroheating installations. 

BS EN 62693 specifies test procedures, conditions, and methods according to which the main parameters and the main operational characteristics of industrial infrared electroheating installations are established. 

A limitation of the scope is that the infrared emitters have a maximum spectral emission at longer wavelengths than 780 nm in air or vacuum and are emitting wideband continuous spectra such as by thermal radiation or high-pressure arcs. 

In industrial infrared electroheating installations, infrared radiation is usually generated by infrared emitters and infrared radiation is significantly dominating overheat convection or heat 

conduction as means of energy transfer to the workload. 

Installations under the scope of BS EN 62693 typically use the Joule effect for the conversion 

of electric energy inside one or several sources into infrared radiation emitted onto the workload. Such infrared emitters are especially. 

• Thermal infrared emitters in the form of tubular, plate-like or otherwise shaped ceramics with a resistive element inside 
• Infrared quartz glass tube or halogen lamp emitters with a hot filament as a source 
• Non insulated elements made from molybdenum disilicide, silicon carbide or comparable materials 
• Restive metallic heating elements made e.g. from nickel-based alloys or iron-chromium-aluminum alloys wide-spectrum arc lamps 

Note: BS EN 62693 is not applicable to 

• infrared installations with lasers or light-emitting diodes (LEDs) as main sources – they are covered by IEC 62471:2006 [9], IEC 60825-1:2007 [6] and IEC/TR 60825-9:1999 [7] 
• Appliances for use by the general public 
• Appliances for laboratory use – they are covered by IEC 61010-1:2010 [8] 
• Electroheating installations where resistance heated bare wires, tubes or bars are used as heating elements, and infrared radiation is not a dominant side effect of the intended use covered by IEC 60519-2:2006 [5] 
• Infrared heating equipment with a nominal combined electrical power of the infrared emitters of less than 250 W 
• Handheld infrared equipment 

Who is BS EN 62693 - Infrared electroheating installations for? 

BS EN 62693 on infrared electroheating installations is useful for: 

• Infrared electroheating installation manufacturers 
• Product design engineers 
• Electrical and mechanical engineers 
• Quality control and testing agencies 
• Inspection authorities 
• Regulatory bodies 

Why should you use BS EN 62693 - Infrared electroheating installations? 

Infrared heating is a heating method that uses infrared radiation to warm nearby surroundings. Through electromagnetic waves in the infrared area, thermal energy is delivered directly to a body with a lower temperature. Because the surrounding air is not heated and is not engaged in the heat transfer, infrared heaters are energy-efficient, convenient, and pose no health risks. 

BS EN 62693 is solely concerned with tests for infrared equipment and installations, providing test procedures, conditions, and testing methods.   

The major guiding principle in BS EN 62693 is to define tests that can be performed with the usual test and measuring equipment available to most kinds of companies, large or small. The tests focus on the performance and efficiency of installations, as these are of major interest for manufacturers and users of such installations. 

BS EN 62693 is intended to enable a fair comparison of installations belonging to a given class. BS EN 62693 includes considerations and tests concerned with energy efficiency, which can be used for assessment of energy use and for energetic optimisation of installations as well.  

Thus, if you’re a manufacturer, BS EN 62693 can demonstrate the performance and efficiency of infrared electroheating installations and determine whether your products are fit for purpose.
