This standard includes procedures for evaluating the compliance of wireless power transfer (WPT) equipment with applicable electromagnetic compatibility (EMC) requirements. Test procedures for radiated field strength and conducted disturbance measurements are included, with reference to established standards, where applicable. WPT RF exposure compliance procedures are not included. This document covers measurement methodologies but is not intended to specify regulatory limits. This standard… read more does not consider test methods for the transmitter or receiver portion of any radio apparatus subcomponents that might be included in the equipment under test (EUT), other than those operating at the WPT frequency (or frequencies). These non-WPT radio subcomponents, which can be related or not to the WPT function of the EUT, are covered by other standards (e.g., ANSI C63.10 [B1] and ANSI C63.26 [B2]). read less

This standard establishes minimum acceptance performance requirements for portable radiation protection instruments used for detection and measurement of ionizing radiation fields or levels of radioactive surface contamination that are near background. For purposes of this standard, portable radiation protection instruments are those battery-powered instruments that are carried to a specific facility or location for use. Specifically, this standard is intended to apply to those instruments… read more utilized to make in-situ measurements for confirmation of residual radioactivity levels that are below criteria established to permit the unrestricted release of a surface area or component from further regulatory controls. This standard is intended to define performance requirements and acceptance testing that supplements those established in ANSI N42.17A-1989 [B7] and ANSI N42.17C-1989 [B8], and to define calibration requirements that supplement those established in ANSI N323A-1998 [B6].1 This standard is applicable to the measurement of gamma, beta, and alpha radiation emissions only. This standard addresses the instrument response requirements for the same range of surface activity covered by the above ANSI standards, but extends the applicable range of dose-rate response below those standards. This is illustrated in Table 1. Throughout this standard, three verbs have been used to indicate the degree of rigor intended for each specific test or performance criterion. The word "shall" is used to denote a requirement; the word "should" to denote a recommendation; and the word "may" to denote a permissible practice. read less

The scope of this standard is to establish minimum performance criteria and test requirements for four categories of alarming electronic radiation measurement instruments used to manage exposure by alerting the emergency responders when they are exposed to photon radiation. The instruments provide rapid and clear indication of the level of radiation exposure and/or exposure rate and readily recognizable alarms. The alarms are both audible and visual, and distinguishable between exposure rate… read more and exposure. Vibratory alarms are optional. Emergency responders include fire and rescue services, law enforcement, and medical services. Other possible users include Critical Infrastructure Key Resources (CIKR) such as heavy equipment, transportation, and utilities personnel. read less

This standard establishes minimum acceptable performance criteria for health physics instrumentation for use in ionizing radiation fields under extreme environmental conditions. Included are testing methods to establish the acceptability of each type of instrumentation. This standard does not specify which instruments or systems are required, nor does it consider the number of specific applications of such instruments. This standard supplements the basic performance requirements for health physics instrumentation as specified in ANSI N42.17A [2]. Specifications in this standard are expected to be called for by the user as required and should not be considered as general specifications.
