This specification covers fluorescent magnetic particles in the form of a dry powder.
Holders, Bases, and Connectors for Solid-State (LED) Light Engines and Arrays UL 8754 1.1 This standard specifies the requirements applicable to holders, bases and connectors intended for solid-state (LED) light engines and arrays for installation in lighting equipment, provided that they employ a...
Field-Replaceable Light Emitting Diode (LED) Light Engines UL 8753 1.1 This standard specifies the requirements applicable to field replaceable light-emitting diode (LED) light engines rated up to 347 volts (nominal) and provided with integral lamp bases of other than the screw, bayonet, or pin...
1.1 These requirements are intended to cover both self-ballasted lamps and self-ballasted lamp adapters rated 120 to 347 V AC nominal for connection to screw-base, pin-base, or recessed single contact (RSC or R7) lampholders. These devices are intended for use in accordance with the National...
1.1 This practice is intended as a standard for fluorescent penetrant inspection of metallic surgical implants. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish...
This specification covers a stable, noncorrosive, water-soluble, highly-penetrating, fluorescent solution which may, but need not, be diluted with an appropriate amount of water for use.
1.1 This practice describes artificial accelerated weathering methods for testing the durability of coatings and related products using fluorescent UV lamps and water apparatus operated in accordance with Practices G151 and G154. 1.2 This practice also makes recommendations for preparation...
5.1 The bispectral or two-monochromator method is the definitive method for the determination of the general (illuminant-independ
5.1 The bispectral or two-monochromator method is the definitive method for the determination of the general radiation-transfer properties of fluorescent specimens (2). In this method, the measuring instrument is equipped with two separate monochromators. The first, the irradiation...
1.1 These requirements apply to light-emitting diode (LED) retrofit kits that are intended to retrofit existing light sources or other components in previously installed luminaires that already comply with one of the standards in 3. 1.2 These kits are intended for use with: a) Luminaires where...
1.1 This test method describes laboratory accelerated weathering procedures using either fluorescent ultraviolet or xenon arc test devices for determining the color stability of building construction sealants. 1.2 Color stability rankings provided by these two procedures may not agree. 1.3...
1.1 This practice is limited to the basic principles for operating a fluorescent UV lamp and water apparatus; on its own, it does not deliver a specific result. 1.2 It is intended to be used in conjunction with a practice or method that defines specific exposure conditions for an application...
1.1 This test method covers a procedure for determination of the performance of film systems used for industrial radiography. This test method establishes minimum requirements that correspond to system classes. 1.2 This test method is to be used only for direct exposure-type film exposed with lead...
5.1 UV-A and visible light sources are used to provide adequate illumination levels for liquid penetrant and magnetic particle examination. UV-A sources, UV-A radiometers, visible light sources, and illuminance photometers are used to verify specified viewing conditions. 5.2 Fluorescence is...
4.1 Light source products conforming to this specification are intended to be used in conjunction with coatings specially formulated with fluorescent colorants as a system for the visual detection of defects in industrial protective coatings. 4.2 Visible fluorescence from the coating...
1.1 This practice describes test conditions and procedures for fluorescent UV and condensation exposures conducted according to Practices G151 and G154 for bituminous roofing and waterproofing materials. (See Terminology G113.) 1.2 The values stated in either SI units or inch-pound units are...
This test method specifies the operating conditions for a fluorescent ultraviolet (UV) and condensation apparatus used for the accelerated exposure of various automotive exterior components.
1.1 This test method describes the instrumental measurement of the colorimetric properties (CIE tristimulus values, luminance factors, and chromaticity coordinates) of fluorescent-retroreflective sheeting and marking materials when illuminated by daylight. 1.2 This test method is generally...
1.1 This practice covers the specific procedures applicable for fluorescent Ultraviolet (UV) exposure of photodegradable plastics conducted in accordance with Practices G151 and G154. This practice also covers the preparation of test specimens and the evaluation of test results. 1.2 Practice...
4.1 Generally, Raman spectra measured using grating-based dispersive or Fourier transform Raman spectrometers have not been corrected for the instrumental response (spectral responsivity of the detection system). Raman spectra obtained with different instruments may show significant variations in...
