When is visual inspection a sufficient solution? Standard illumination level in a light booth measured in lux Star, Inc. | August 8, 2016. Targeted task lighting can provide the necessary amount of light at workspaces without over-illuminating ancillary spaces; ambient light levels of 300 lux are sufficient for most tasks. In these applications, the right lighting is a must. The requirements of visual examination are: Illumination should be at least 350 Lux (minimum) but it is recommended to carry out visual inspection at an illumination of more than 500 Lux. The inspectors eye should be within the radii of 600 mm of the surface of item being inspected and the viewing angle must not be less than 30 degrees. Earlier it was common with light levels in the range 100 - 300 lux for normal activities. NASA-STD-8739.3.

Lighting. Factors other than light level may affect visual conditions. But these light levels must be provided from low-glare and shadow-free lighting systems. Step-4: Compare the measured lux values with standard values as reference and identify locations as under lit and over lit areas. 5. Brightness levels also contribute to the perception of spaciousness, as well as to the overall visual appeal of illuminated spaces. Room Type. These figures are based on the recommended lux levels by CIBSE (Chartered Institute of Building Services Engineers) and the code for interior lighting. from 400 to 1500 Lux in normal cleanrooms): Some coupon studies have indicated that light levels between 200 and 1400 Lux may not alter an inspector's visual inspection; still, this should be demonstrated via actual situations. defects (1), as well as other product characteristics such as fill level, discoloration, or clarity may also be detected during visual inspection, and non-conforming units should be rejected using the methods described in this chapter. 300 lx to 500 lx). By Mathew Hildner and Aarash Navabi, CPIP, L.J. For laboratories the general lighting should have an illumination level of 500 lux. 20-30 FC. Tables are for guidance .
