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.
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 11611 was prepared by Technical Committee ISO/TC 94, Personal safety -- Protective clothing and
equipment, Subcommittee SC 13, and by Technical Committee CEN/TC 162, Protective clothing including
hand and arm protection and lifejackets in collaboration.
ISO 11611:XXXX cancels and replaces ISO 11611:2007, which has been technically revised to:
a) include test procedure for dry-cleaning in normative references;
b) modify clause in design requirements regarding garment overlaps;
c) modify clause in design requirements regarding garment sizes;
d) modify clause for ageing due to washing (maximum number of cleaning procedures as indicated by the
manufacturer);
e) modify pretreatment clause to include requirements for single use garments;
f) modify pretreatment clause to specify dimensional stability is carried out after five cleaning cycles;
g) include modified procedure when measuring dimensional stability;

DRAFT INTERNATIONAL STANDARD ISO/DIS 11611

Protective clothing for use in welding and allied processes
1 Scope
This International Standard specifies minimum basic safety requirements and test methods for protective
clothing including hoods, aprons, sleeves and gaiters that are designed to protect the wearer's body including
head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable
risks. For the protection of the wearer’s head and feet, this International Standard is only applicable to hoods
and gaiters. This International Standard does not cover requirements for hand protection or visors for face
protection.
This type of protective clothing is intended to protect the wearer against spatter (small splashes of molten
metal), short contact time with flame, radiant heat from the arc, and minimizes the possibility of electrical
shock by short-term, accidental contact with live electrical conductors at voltages up to approximately
100 V d. c. in normal conditions of welding. Sweat, soiling or other contaminants can affect the level of
protection provided against short-term accidental contact with live electric conductors at these voltages. This
International Standard specifies two classes with specific performance requirements (see Annex A), i.e. Class
1 being the lower level and Class 2 the higher level.
⎯ Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of
spatter and radiant heat.
⎯ Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of
spatter and radiant heat.
Details are given in Table 1 and Annex A
For adequate overall protection against the risks to which welders are likely to be exposed, personal
protective equipment (PPE) covered by other standards should additionally be worn to protect the head, face,
hands and feet.

protective clothing such as hoods, sleeves, apron and gaiters shall cover the intended areas if worn with a suit
of appropriate size and shall also meet the requirements of this International Standard.
4.3 Sizes
Garment sizes shall be in accordance with the requirements of ISO 13688.
Conformity shall be checked by visual inspection including an assessment of fit and physical measuring when
the appropriate size of clothing is donned by a wearer, when performing the movements normally encountered
during use.
4.4 Pockets
Where garments are constructed with pockets, the pockets shall be constructed to the following design:
a) pockets with external openings, including patch pockets shall be made of material(s) conforming to 6.7
and 6.8.
b) external opening pockets including pass through openings shall be flapped except for:
