Exposure Hazard Value (EHV)
is a ratio of the Exposure Level (distance, exposure time) to
Exposure Limit Value (ELV). When EHV is greater than 1, the device has exceeded the
Exposure Limit Values for a particular Risk Group. The ELV is the level where optical radiation
to the eye or skin is not expected to result in adverse biological effects.
The
Hazard Distance (HD)
is the distance from the source at which the Exposure Level equals
the appropriate ELV. In other words, when EHV=1 for a particular Risk Group.
Regarding the Cornea / Lens infrared hazard of this product, the Exposure Hazard Value (EHV)
at a test distance of 200mm is 2.19 based on EXEMPT Group exposure limits. The EHV based
on Risk Group 1 limits is 0.386. The HD for the Exempt Group is 297 mm.
Regarding the Retinal Blue Light hazard, the EHV is 22.9 based on the EXEMPT Group
exposure limits and a test distance of 200 mm. The EHV based on Risk Group 1 limits is 0.266.
The HD for the Exempt Group is 2675 mm.
