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. This practice is intended to induce property changes associated with end-use conditions,...
5.1 Weathering and durability testing often requires the computation of the effects of radiant exposure of materials to various optical radiation sources, including lamps with varying spectral power distributions and outdoor and simulated sunlight as in Test Methods E972, G130, and...
4.1 The activation spectrum identifies the spectral region(s) of the specific exposure source used that may be primarily responsible for changes in appearance and/or physical properties of the material. 4.2 The spectrographic technique uses a prism or grating spectrograph to determine the effect on...
4.1 This test method describes the procedure to evaluate or compare, or both, the durability of sealants when subjected to accelerated weathering and cyclic movement in a joint. 4.2 Sealant installation procedures, design considerations and movement during cure affect the aging processes and are...
4.1 Materials made from photodegradable plastics are intended to show relatively rapid deterioration of chemical, physical, and mechanical properties when exposed to light, heat, and water after fulfilling their intended purpose. This practice is intended to induce property changes associated with...
1.1 This practice is limited to the basic principles and procedures for operating a xenon arc 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...
1.1 This practice covers three types of laboratory weathering exposure procedures for evaluating the effect of actinic radiation, heat, and moisture on sealants. 1.2 The exposure sources used in the three types of artificial weathering devices are the filtered xenon arc, fluorescent ultraviolet...
This LM outlines factors that can cause differences between calculated and measured illuminance and luminance values of outdoor high intensity discharge (HID) and low pressure sodium (LPS) lamps and luminaires. It does not offer solutions, nor does it quantify all of the possible...
The purpose of this Standard is to describe a method to establish reasonable claims of initial light output equivalency for single-ended omnidirectional LED replacement lamps that are intended to replace HID lamps. The method accounts for two factors that influence the equivalency...
This European Standard specifies the required data for lamps and luminaires for the verification of conformity to the requirements of EN 12464-1 and EN 12464-2. It also specifies data that are commonly used for lighting of indoor and outdoor work places. When these data are provided,...

1.1 The method described in this standard applies to the indoor transfer of calibration from reference to field radiometers to be used for measuring and monitoring outdoor radiant exposure levels. 1.2 This test method is applicable to field radiometers regardless of the radiation receptor...
These requirements apply to devices that: Sustain a flame over the fuel surface in an open reservoir; Sustain a flame that does not require external ventilation to remove the combustion emissions, and are therefore ventless; Burn a liquid, gelled, or otherwise non-solid fuel in an open reservoir or...
1.1 These requirements apply to devices that: 1.1.1 Sustain a flame over the fuel surface in an open reservoir; 1.1.2 Sustain a flame that does not require external ventilation to remove the combustion emissions, and are therefore ventless; 1.1.3 Burn a liquid, gelled, or otherwise non-solid fuel...
This Code specifies minimum requirements for the installation of large oil-burning equipment. Note: The intent of this Code is to apply to multi-unit residential, commercial, institutional, and industrial buildings in accordance with the provincial building code or, in the absence of such...
IEC 60598-2-17:2017 specifies requirements for stage, television, film and photographic studio luminaires (including spot and floodlighting projectors) for use outdoors and indoors, with electric light sources on supply voltages not exceeding 1 000 V. This second edition cancels and replaces the...
