accompanying information. The requirements of this document are not expected to
apply to symbols, which are specified in other standards.

Note 2: The information provided by the manufacturer does not include shipping documents
and promotional materials. However, some regulatory authorities with jurisdiction (as
defined in 3.1 of ISO 16142-1:2016) may consider such supplementary information to be
information provided by the manufacturer.
Note 3: The main purpose of the information provided by the manufacturer is to identify the

basic information on the safety, performance, appropriate use of the medical device.
Note 4: See Figure 1.

Manufacturer
A natural or legal person in whose name a medical device intended to be available
is manufactured and who is responsible for the design and/or manufacture of the
medical device, whether the design and/or manufacture of the medical device is
carried out by that natural or legal person or by others on his or her behalf.
Note 1: This “natural or legal person” has the ultimate legal responsibility for ensuring
compliance with all applicable regulatory requirements in the country or jurisdiction, in
which the medical device is intended to be available or sold, unless the regulatory authority
(RA) in that jurisdiction expressly imposes liability on another natural or legal person.
Note 2: The manufacturer's responsibilities are described in other Global Harmonization
Organization (GHTF) guidance documents. These responsibilities include meeting pre-
marketing requirements and post-marketing requirements, such as adverse event reporting
and corrective action notifications.
Note 3: “Design and/or manufacture” includes the specification, production, manufacture,
assembly, processing, packaging, repackaging, labeling, relabeling, sterilization,
installation or remanufacturing of medical devices; or combining multiple devices, which
may also include other products, for medical purposes.
Note 4: Any natural or legal person, who assembles or modifies a medical device provided
by others for an individual patient, in accordance with the instructions for use, is not a
manufacturer, if the assembly or modification does not change the intended use of the
medical device.
Note 5: Any natural or legal person, who does not change the intended use of a medical
device or modify a medical device in the name of the original manufacturer, meanwhile
makes the device available for use in its name, is considered to be the manufacturer of the
modified medical device.
Note 6: Authorized representatives, distributors or importers, who only add their address
and contact information to the medical device or packaging, without covering or changing
the existing marking, are not considered manufacturers.
Note 7: For accessories that are subject to medical device supervision, the natural or legal
person responsible for the design and/or manufacture of the accessory is considered the
manufacturer.

Note 2: The marking is different from the "ontology direct identification", which is usually
described in Unique Medical Device Identification (UDI) standards and regulations. UDI
"Ontology direct identification" is an indication.

4 General requirements
4.1 Symbols to be adopted in the future
The symbols proposed for use in this document comply with the following requirements:
a) Symbols adopted in the future shall be confirmed according to YY/T 0466.2,
except for the symbols as registered in ISO 7000, ISO 7010 or IEC 60417;
b) Any symbol shall apply to a range of medical devices and have global or regional
applicability.
4.2 How to use
The symbols used in this document are as follows:
a) When identification requires the use of symbols as an appropriate method for
conveying necessary information for the correct use of a medical device, the
symbols given in Table 1 may be marked on the medical device, displayed on its
packaging or in information provided by the manufacturer;
Note 1: ISO and IEC jointly maintain an online database of graphical symbols for equipment
(https://www.iso.org/obp/ui/#home). This database covers all graphical symbols of ISO
7000, ISO 7001, IEC 60417. In this database, each graphic symbol is displayed and
identified by a reference number and title. Graphical symbols are obtained in different
formats (such as AI, DWG, EPS); when applicable, some additional data are provided.
b) The manufacturer shall determine the appropriate dimensions of the symbol, so
that the symbol is legible for its intended function;
Note 2: This document does not specify the color or minimum size of the symbols in Table
1, nor the relative size of the symbols and the relative size of the information they display.
Note 3: For guidance on the application of graphical symbols, see IEC 80416-
3:2002+A1:2011.
Note 4: See Appendix B for guidelines on the use of general prohibited symbols and
negative symbols.

Other standards specify additional symbols, that are applicable to specific varieties or
types of medical devices or that are applicable to specific situations. References provide
examples of the sources of these additional symbols.
5 Symbols
Use of the symbols given in this document follows the following requirements:
a) Where appropriate, the necessary information for the correct use of the medical
device shall be marked on the medical device, on its packaging or in
accompanying information, by using the corresponding symbols given in Table 1;
b) The manufacturer may use any appropriate symbol;
Note 1: For ease of use, Table 1 is grouped by symbol category. As far as usage is concerned,
the categories of symbol groupings have no meaning. The order in which symbols appear
and the categories they are in have no priority. See Appendix A for examples of symbol
usage.
