Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
⎯ an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
⎯ an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 16974 was prepared by Technical Committee ISO/TC 94, Personal safety — Protective clothing and
equipment, Subcommittee SC 15, Respiratory protective devices.

supplied by the manufacturer
1 Scope
This Technical Specification gives guidance on the marking to be used on respiratory protective devices
(RPD) and the information to be supplied by the manufacturer/supplier.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 7000, Graphical symbols for use on equipment — Index and synopsis

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 7000 and ISO 16972 apply.
4 General
4.1 Levels of marking and information system used for RPD
The marking and information system required for RPD shall have the following two levels.
Level 1: RPD system
For Level 1 the manufacturer shall provide minimum marking and information, as described in Clause 5,
on or with the respiratory protective device as worn by the individual.
Level 2: RPD components and replacement parts
For Level 2 the manufacturer shall provide minimum marking and information, as described in Clause 6,
on some components and replacement parts. This is only applicable to the listed components and
replaceable parts which are designated by the manufacturer as replaceable. Whenever feasible, this
marking shall be included on each individual part. If this is not feasible, the marking shall be on the
smallest commercially available package of parts.
4.2 Written information and marking
4.2.1 Written information should be at least in the official language(s) of the country of destination, or
nationally recognized language(s), as accepted.
4.2.2 Written information should explain the meaning of any graphical symbols.

4.2.4 When applicable, marking and information should be added in order to comply with national or local
regulations.
4.2.5 If additional marking is required in parts of the ISO 17420 series, the system or component shall be
marked accordingly.
5 Level 1: RPD system
5.1 Marking of RPD
The RPD should include at least the following marking:
a) manufacturer name, logo or identifying mark;
b) RPD model number, name or any other type identifying mark;
c) reference to ISO 17420-1 or ISO 17420-2, as applicable;
d) RPD classification;
NOTE This classification requirement will be updated in the next revision after a classification scheme has been
created.
e) means of traceability;
NOTE Format to be chosen by the manufacturer.
f) instructions to read the information supplied by the manufacturer (which may be done using ISO graphical
symbols);
g) size designation, if applicable.
5.2 Accompanying information
In addition to 5.1, information supplied by the manufacturer should include all the information, if applicable,
necessary for trained and qualified personnel on:
a) application(s) and limitations of the RPD and warnings and cautions associated with its use;
b) RPD model number, name or any other type identifying mark;
c) RPD classification;
d) assembly and operational instructions (description of pre-use checks and the mounting and orientation of
RPD components and parts);
e) meaning of graphical symbols;
f) warning devices, such as alarms, signals, etc., related to the use of the product;
g) storage conditions prior to use and between each use;

j) correct donning and doffing;
k) shelf life, which may include a shelf life indicator attached to the packaging, RPD, component or expiry
