Foreword
This Standard is identical to the International Electrotechnical Commission IEC
601-1-3.1994 “Medical electrical equipment - Part 1. General requirements for
safety 3. Collateral standard. General requirements for radiation protection in
diagnostic X-ray equipment” (first edition).
The purpose of developing this Standard is to provide uniform general
requirements for radiation protection in medical diagnostic X-ray equipment, to
meet the needs of international trade, technical and economic exchanges, and
adoption of development of international standards.
electrical equipment - Part 1. General requirements for safety” (hereinafter
referred to as the General Standard).
Annexes AAA, BBB, and CCC in this Standard are for information only.
To ensure the applicability of terms, the terms appearing in this Standard are
explained as follows.
Installation instructions are also referred to as assembling instructions.
Significant zone of occupancy is also referred to as significant zone of
occupancy of space occupying area. Beam applicator, in some cases, is also
referred to as a beam emitter or beam concentrator. Primary protective
known as the manufacturer or producer. Beam limiting device is also known as
the beam limiter.
This Standard was proposed by National Medical Products Administration.
This Standard shall be under the jurisdiction of National Technical
Subcommittee 1 on Medical X-ray Equipment and Appliances of
Standardization Administration of China.
Drafting organization of this Standard. Liaoning Medical Device Test Institute.
Main drafters of this Standard. He Yuhua, Wang Shoumin, Xia Lianji, Li Chuan,
Shen Hua.
Part 1. General requirements for safety
3. Collateral standard. General requirements for
radiation protection in diagnostic X-ray equipment
SECTION 1. GENERAL
1 Scope, object and relationship to other standards
1.201 Scope
This Collateral Standard applies to medical diagnostic X-RAY EQUIPMENT and
to sub-assemblies of such EQUIPMENT.
1.202 Object
protection against IONIZING RADIATION in medical diagnostic X-RAY
EQUIPMENT, in order that the DOSE EQUIVALENT to the PATIENT, the
OPERATOR and other staff can be kept as low as reasonably achievable.
Some of the requirements in this Collateral Standard include variations for
different types of X-RAY EQUIPMENT. This is intended to widen the scope
within which the Collateral Standard can be applied usefully without addition or
modification, especially in respect of types of X-RAY EQUIPMENT that are
commonly used in MEDICAL DIAGNOSTIC RADIOLOGY.
The requirements in this Collateral Standard apply mainly in respect of X-
energy used to generate X-RADIATION, which is also an important aspect of
RADIATION PROTECTION, are included in GB 9706.1 “Medical electrical
equipment - Part 1. General requirements for safety” and in Particular
Standards for the safety of the EQUIPMENT concerned.
1.203 Relationship to other standards
1.203.1 GB 9706.1
