5.3 UV-A light sources may emit visible light above 400 nm (400 Å), which may reduce the visiblity of fluorescent indications. 1.2.2 For use in the preparation of internal documentation dealing with liquid penetrant or magnetic particle examination of materials and parts.
1.3 The values stated in SI units are to be regarded as standard. Ultraviolet (UV) light is a type of radiation. 5.2 Fluorescence is produced by irradiating the fluorescent dyes/pigments with UV-A radiation. 1.1 This guide describes the use of UV-A/Visible light sources and meters used for the examination of materials by the liquid penetrant and magnetic particle processes. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard. The UV range of the electromagnetic radiation spectrum extends from 10 nm to 400 nm.
It has more energy than radio waves or visible light but less energy than X-rays or gamma rays.

UV Light and Health Effects.
What safety considerations should I take into account? ISO 4892-3 Plastics--Methods of Exposure to Laboratory Light Sources--Part 3, Fluorescent UV Lamps. UV and Blue-Light Hazards • UV and bl eUV and blue-light phototo icitphototoxicity are the key potential hazards in lamp safety standards – Concerns of chronic exposure – Two infrared limits and retinal thermal limits are seldom and isthermal limits are seldom and issue • By contrast, laser safety standards are almost always focused on All UV ranges and bands are invisible to the human eye.
Standard References, 4.1 The ability of a plastic material to resist deterioration of its electrical, mechanical, and optical properties caused by exposure to light, heat, and water can be very significant for many applications. endstream endobj 639 0 obj <> endobj 626 0 obj <> endobj 625 0 obj <> endobj 103 0 obj <> endobj 627 0 obj [51 0 R 56 0 R 112 0 R 160 0 R 266 0 R 268 0 R 270 0 R] endobj 51 0 obj <. The fluorescent dyes/pigments absorb the energy from the UV-A radiation and re-emit light energy in the visible spectrum.
The exposure used in this practice is not intended to simulate the deterioration caused by localized weather phenomena, such as, atmospheric pollution, biological attack, and saltwater exposure.
