The IEC 61549 Standard for fragment retention lamps (FRLs) has been in effect since April 2013.
It is designed to assist electrical contractors, distributors, end users and certification bodies in identifying glass fragment retention, in applications where risk of contamination from accidental breakage requires control.
Below are the main key points for a coated lamp to be compliant to the IEC 61549 Standard:
Adtech Polymer Engineering Ltd manufacture heat shrinkable FEP to cover lamps and can cover virtually all lamp configurations, including straight, compact, circline (circular) and tight U-bend styles.
Our FEP lamp coatings have a maximum continuous operating temperature of 200°C and do not embrittle or discolour over time. The integrity of the fluoropolymer coating will long outlast the manufacturers specified lifespan of the lamp and all our lamp coating material has passed the mandatory 4 metre drop test.
FEP is the best solution for use with UVA and UVC lamps as the transmission rate is not dramatically reduced by the coating. On average with a 0.25mm thick coating you will see an overall loss of approximately 4% for UVA and 13% for UVC, this ensures the lamps remain effective.
Yes, providing the FEP heat shrink has been applied correctly and to the criteria outlined in the IEC 61549 specification, all lamps coated with our ADTEX-S material would be compliant, for use in glass free environments.
Here at Adtech, we are specialists in delivering innovative fluoropolymer solutions for your technical applications. We understand that every customer’s application is different, so our knowledgeable customer service and R&D teams are on hand to discuss your project and application.
