Developing a procedure for testing non-laser optical radiation emitted by machinery

Project manager: Andrzej Pawlak M.Sc. (Eng.)

Project summary:

The main aim of the task consisted in developing testing procedures for non-laser optic radiation emitted by machinery for the purposes of categorizing machinery regarding hazards related to that radiation. The most frequently used industrial machinery that emits ultraviolet, infra-red and visible radiation was surveyed. To determine potential hazards, the intensity of ultraviolet radiation emitted by selected machinery used in the food, electronic and printing industries was measured. Two testing procedures for measuring the effective intensity of ultraviolet radiation (NBP-1) and measuring the intensity of infra-red radiation (NBP-1) were developed for assessing the emission category of machinery, including estimation of measurement uncertainty. A testing procedure for measuring visible radiation (NBP-3) assessing the emission category of machinery, including estimation of measurement uncertainty, was also developed. After receiving up-to-date calibration certificates for a set of probes from LOT-Oriel Ltd. necessary calculation corrections were introduced to the estimated uncertainties in the already-developed procedures NBP-1 and NBP-2. Then, by making relevant measurements for real machinery, the developed procedures were verified in practice. Procedure NB-3 was verified with measurements of effective energy luminance emitted during photocopying done with a photocopier/printer CPS 700 from OCE. An extension of the scope of accreditation for CIOP-PIBʼs Laboratory of Optic Radiation was applied for.
