The scope of this standard is to describe the concepts, techniques and limitations of the Finite-Element method and to specify models and procedures for validation and uncertainty assessment for the Finite-Element Method when used for determining the spatial-peak specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless devices and provides benchmark data for the simulation the SAR in such phantoms or models.

This standard does not recommend specific SAR limits since these are found elsewhere, e.g., in IEEE C95.1 [1] or in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [2].

NOTE Cubical averaging volumes are applied in all current experimental standards for the assessment of psSAR and recommended by [1], [2] and [3]. Other averaging volumes have been proposed, e.g., in [2], and may be included in future revisions of this standard.

This part of IEC 61163 provides guidance on RSS techniques and procedures for electrical, electronic, and mechanical components. This international standard is procedural in nature and is not, and cannot be, exhaustive with respect to component technologies due to the rapid rate of developments in the electrical component industry.

This standard is:

intended for component manufacturers as a guideline;

intended for component users as a guideline to negotiate with component manufacturers on RSS requirements;

intended to allow the planning of a RSS process in house to meet reliability requirements or to allow the re-qualification of components for specific, upgraded, environments;

intended as a guideline to sub-contractors who provide RSS as a service.

This standard is not intended to provide test plans for specific components or for delivery of certificates of conformance for batches of components.

This International Standard is intended to define a procedure to verify if a reliability of an item/system complies with the stated requirements. The requirement is assumed to be specified as the percentage of success (success ratio) or the percentage of failures (failure ratio).

This document can be used where a number of items are tested (trials) and classified as passed or failed. It can also be used where one or a number of items are tested repeatedly. The procedures are based on the assumption that the probability of success or failure is the same from trial to trial (statistically independent events). Planes for fixed trial/failure terminated tests as well as truncated sequential probability ratio tests (SPRT) are included. This document contains extensive tables with ready-to-use SPRT plans and their characteristics for equal and non-equal risks for supplier and customer.

In the case of the reliability compliance tests for constant failure rate/intensity, IEC 61124 should be applied.
