BS EN 60519-9:2005

What is BS EN 60519-9 - High-frequency dielectric heating installations about? 

BS EN 60519 is a European standard series that discusses safety in electroheat installations. The object of BS EN 60519-9 is to provide requirements for high-frequency dielectric heating installations to ensure the installations are safe, reliable and effective for use.  

BS EN 60519-9 is the nineth part of the IEC 60519 series that is applicable to industrial high-frequency dielectric heating installations for the purpose of thermal applications such as melting, drying, welding, insect extermination, and gluing of partially or non-conductive materials such as plastics, wood, rubber, textiles, glass, ceramic, paper, bamboo, foodstuffs, etc. in both normal and protective atmospheres, using, for example, inert gases or vacuum. 

BS EN 60519-9 relates to high-frequency dielectric heating installations with nominal frequency in the range from 1 MHz to 300 MHz with rated useful output power greater than 50 W. 

The voltage band according to IEC 60519-1 relates to the mains supply voltage. In some circuits of the dielectric heating installation, the d.c., a.c. or radio-frequency voltages can have greater values. 

Note: In accordance with CISPR 11, there are preferred frequencies designated by the international telecommunication Union for use as fundamental ISM frequencies. 

Who is BS EN 60519-9 - High-frequency dielectric heating installations for? 

BS EN 60519-9 on high-frequency dielectric heating installations is useful for: 

• Electric oven/furnace manufacturers 
• Product design engineers 
• Mechanical engineers 
• Quality control and testing authorities 

Why should you use BS EN 60519-9 - High-frequency dielectric heating installations? 

Dielectric heating installation is an installation comprising the dielectric heating generator, high-frequency transmission lines (if any) and the dielectric applicator.  

BS EN 60519-9 provides best industry guidance on protective measures in the dielectric heating generator, protective measures for use in dielectric applicators and tests for protective measures. 

Thus, compliance with BS EN 60519-9 can improve the heating efficiency and ensure the safety of dielectric heating installations. As a result, you can achieve adequate protection against direct contact and minimize risk of potential hazards to the operating personnel from flames, explosion or projection of matter. 

What’s changed since the last update? 

BS EN 60519-9:2005 supersedes BS EN 60519-9:1996 which is withdrawn. BS EN 60519-9:2005 includes some technical changes with respect to BS EN 60519-9:1996. These include: 

• Requirements for the protection against direct contact have been revised 
• The structure has been adjusted to the latest ISO/IEC Directives, in particular the scope, object and introduction of normative references 
• Definitions have been brought into line with 60050-841:2004
