Foreword
The "Medical electrical equipment" series of standards is divided into two parts:
- Part 1: General and collateral requirements;
- Part 2: Particular requirements.
This Part is Part 1-6.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part uses the redraft law to modify and adopt IEC 60601-1-6:2013 "Medical
electrical equipment - Part 1-6: General requirements for basic safety and
essential performance - Collateral standard: Usability".
The technical differences between this Part and IEC 60601-1-6:2013 and their
reasons are as follows:
- As for the normative references, this Part has made adjustments with
technical differences, to adapt to the technical conditions of China. The
adjustments are mainly reflected in Clause 2 “Normative references”. The
specific adjustments are as follows:
 Replace IEC 60601-1:2005+AMD1:2012 with GB 9706.1-2020, which
modifies and adopts the international standard;
 Replace ISO 14971:2007 with YY/T 0316, which is identical to the
international standard;
 Replace IEC 60601-1-8:2006+AMD1:2012 with YY 9706.108, which
modifies and adopts the international standard.
This Part has made the following editorial changes:
- ADD A.3 to Annex A, which gives the correspondence between international
standards and current Chinese national standards or industry standards;
- Retain the title of Annex B; delete the specific content of Annex B.
Attention is drawn to the possibility that some of the elements of this document
may be the subject of patent rights. The issuing authority of this document shall
not be held responsible for identifying any or all such patent rights.
This Part was proposed by National Medical Products Administration.
This Part shall be under the jurisdiction of National Technical Committee 10 on
Medical electrical equipment - Part 1-6: General
requirements for basic safety and essential
performance - Collateral Standard: Usability
1 Scope, object and related standards
1.1 * Scope
This Part specifies a PROCESS for a MANUFACTURER to analyse, specify,
design, VERIFY and VALIDATE USABILITY, as it relates to BASIC SAFETY
and ESSENTIAL PERFORMANCE of MEDICAL ELECTRICAL EQUIPMENT,
hereafter referred to as ME EQUIPMENT.
This USABILITY ENGINEERING PROCESS assesses and mitigates RISKS
caused by USABILITY problems associated with CORRECT USE and USE
ERRORS, i.e., NORMAL USE. It can be used to identify but does not assess
or mitigate RISKS associated with ABNORMAL USE.
If the USABILITY ENGINEERING PROCESS detailed in this Part has been
complied with and the acceptance criteria documented in the USABILITY
VALIDATION plan have been met (see 5.9 of YY/T 1474-2016), then the
RESIDUAL RISKS, as defined in YY/T 0316, associated with USABILITY of ME
EQUIPMENT are presumed to be acceptable, unless there is OBJECTIVE
EVIDENCE to the contrary (see 4.1.2 of YY/T 1474-2016).
Note: Where an asterisk (*) is used as the first character of a title or the beginning of a
paragraph or table title, it means that there is a related guidance or rationale in Annex
A.
1.2 Object
The object of this Part is to specify general requirements that are in addition to
those of the general standard and to serve as the basis for particular standards.
1.3 Relationship with other standards
1.3.1 GB 9706.1
For ME EQUIPMENT, this Part complements GB 9706.1.
When referring to GB 9706.1 or to this Part, either individually or in combination,
the following conventions are used:
- "the general standard" designates GB 9706.1-2020 alone;
- "this Part" designates YY/T 9706.106-2021 alone;
- "this standard" designates the combination of the general standard and this
Part.
1.3.2 Particular standards
A requirement in a particular standard takes priority over the corresponding
requirement in this Part.
