This Part specifies the principle, procedures, result calculation and other related contents for determination of phenol adsorption of granular activated carbon from coal. This Part is applicable to determination of phenol adsorption of granular activated carbon from coal. It is also applicable to powdery activated carbon from coal.
This Standard relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 9 kHz up to 80 MHz. Equipment not having at least one conducting cable (such as mains supply, signal line or earth connection), which can couple the equipment to the disturbing RF fields is excluded. This Standard does not intend to specify the tests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to all concerned product committees of the IEC. The product committees (or users and manufacturers of equipment) remain responsible for the appropriate choice of the test and the severity level to be applied to their equipment.
This Part of GB/T 17626 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This Standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The objective of this Standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations.
This Part of GB/T 17626 relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltage from switching and lightning transients. Several test levels which relate to different environment and installation conditions are defined. These requirements are developed for and are applicable to electrical and electronic equipment. The objective of this Standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this Part describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
