Test methods are specified for complete devices or parts of devices that are int

25、ended to comply with the performance standards.The following definitions apply in understanding how to implement an ISO International Standard and other normative ISO deliverables (TS, PAS, IWA): “shall” indicates a requirement; “should” indicates a recommendation; “may” is used to indicate that som

26、ething is permitted; “can” is used to indicate that something is possible, for example, that an organization or individual is able to do something.3.3.1 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a requirement as an “expression in the content of a document conveying criteria to

27、be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted.”3.3.2 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a recommendation as an “expression in the content of a document conveying that among several possibilities one is recommended

28、as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited.”vi ISO 2015 All rights reservedBS ISO 16900-13:20
