Specifies two preferred methods: the outdoor calibration (with the pyranometer in a horizontal position, in a tilted position, or at normal incidence) and the indoor calibration (using an integrating sphere with shaded or unshaded lamp, or at normal incidence). Applicable to most types of field pyranometers regardless of the type of radiation receptor employed.

Its use is mandatory for the calibration of secondary standard pyranometers according to ISO 9060, and is recommended for the calibration of pyranometers which are used as reference instruments in comparisons. Is intended for use by test institutions or test laboratories equipped with well-maintained pyrheliometers and is applicable to all pyranometers. The object is to promote the uniform application of reliable methods to calibrate pyranometers, since accurate calibration factors are the basis of accurate hemispherical solar radiation data which are needed for solar energy test applications or simulations.

This International Standard is one of a series of International Standards specifying methods and instruments for the measurement of solar radiation. Pyrheliometers are used to measure direct solar irradiance. The data collected are used for — the determination of the efficiency of concentrating collectors, — the determination of the direct beam resource for concentrating solar energy devices as well as for determining their siting, sizing, etc., and — the accurate determination of hemispherical solar radiation as a sum of the measured direct solar and diffuse solar radiation. The calibration hierarchy of pyrheliometers specified in this International Standard follows the scheme developed by the World Meteorological Organization (WMO) [1], and the classification and specification used are prescribed in ISO 9060. During the elaboration of this International Standard, extensive reference was made to ASTM 816-81 [2].

CISPR 35:2016 applies to multimedia equipment (MME) having a rated AC or DC supply voltage not exceeding 600 V. The objectives of this document are:<br /> - to establish requirements which provide an adequate level of intrinsic immunity so that the MME will operate as intended in its environment in the frequency range 0 kHz to 400 GHz; and<br /> - to specify procedures to ensure the reproducibility of tests and the repeatability of results.
