Glass Material UV Transmission Testing

Project Description

Large Company needs Laboratory for UV transmission in glass material. Ultraviolet Light TransmissionUltraviolet light transmission through the sight glass should be kept to a minimum as it has adetrimental effect on the insulating oil. Deterioration of the oil will result in poor oil visibilityand deterioration of electrical properties which could adversely affect the performance of thebushing.For the purpose of measuring the light transmission, the test shall be done on a

0.4 inch (10 mm)thick, 3 inch (7.6 cm) diameter flat polished sample taken from each furnace melt.

The sampleand the melt shall be considered to have passed the test if it meets the following requirements:Wave Length, millimicronMaximum Transmission Percent40053901380-3000.35Using a spectrophotometer or similar equipment, measure the ultraviolet light transmission at thewave lengths specified above.
