Spellman Approved to Perform In-House UL Testing

February 13, 2006

Hauppauge, New York -- Spellman High Voltage announced that it has received a certificate of qualification from Underwriters Laboratories Inc. (UL) stating that the company has been assessed and found eligible to participate in UL's Client Test Data Program (CTDP). The CTDP allows Spellman to build high voltage power supplies and Monoblock® X-Ray sources tested in Spellman's own facility without the need for a client engineer from UL to witness the testing.

The assessment process involved verification of scheduled calibration of measurement instruments in Spellman's engineering labs and in its quality department. These calibrated instruments must also be routinely calibrated against National Institute of Standards and Technology (NIST) laboratories standards. The assessment verified that all personnel knew the testing procedure and the calibration procedure.

By qualifying for the CTDP program, data from Spellman's tests are now submitted to UL, and approval from UL can be granted in as little as 5 days. In the past, Spellman has had to wait after building high voltage products for UL engineers to come to its global headquarters in Hauppauge (New York, USA) and witness the testing. This wait has generally been 4-6 weeks. Spellman can now save the extra time of waiting and it allows Spellman to get new UL-approved products to market sooner.
