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 6530 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 162, Protective clothing including hand and arm protection and lifejackets, in collaboration with
Technical Committee ISO/TC 94, Personal safety — Protective clothing and equipment, Subcommittee SC 13,
Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6530:1990), which has been technically
revised.
ISO 6530:2005(E)
Introduction
This International Standard specifies a test method for measuring indices of penetration, absorption and
repellency for protective clothing materials against low-volume, low-pressure splashes of liquid chemicals,
usually chemicals of low volatility. ISO 13994 may be used for determining the penetration resistance of
protective clothing materials against chemicals in larger volume and higher pressure splashes.
Clothing made of these materials should not be used as the sole means of protection where resistance to
permeation by chemicals at the molecular level (see ISO 6529) is essential and where a complete barrier to
liquid (or gaseous) chemicals is required (e.g. risk of exposure to massive and forceful discharges of
concentrated liquid chemicals).
Data obtained by this test method may be used as a guide for screening protective clothing materials. Clothing,
which has been developed from materials selected by this method of test should be used, therefore, only in
well-defined circumstances when an evaluation of the finished item has indicated an acceptable level of
performance (in laboratory and field-testing of a garment, consideration of exposure levels to specified
chemicals, etc.).
In interpreting the results of the test method, the influences of the physical properties of the test chemical (e.g.
volatility) should also be taken into consideration.

INTERNATIONAL STANDARD ISO 6530:2005(E)

Protective clothing — Protection against liquid chemicals —
Test method for resistance of materials to penetration by
liquids
1 Scope
This International Standard specifies a test method for the measurement of indices of penetration, absorption
and repellency for protective clothing materials against liquid chemicals, mainly chemicals of low volatility.
Two levels of the potential performance of materials are assessed by this method of testing to meet with
possible requirements for protection against
a) deposition on the surface of a material, at minimal pressure, of spray droplets up to coalescence or
occasional small drips;
b) contamination by a single low-volume splash or low-pressure jet, allowing sufficient time to divest the
clothing or take other action as necessary to eliminate any hazard to the wearer from chemical retained
by the protective garment, or, in circumstances where pressure is applied to liquid contaminants on the
surface of the clothing material, as a result of natural movements of the wearer (flexing of contaminated
areas of clothing at arms, knees, shoulders) and contact with contaminated surfaces (e.g. walking
through sprayed foliage).
2 Definitions
For the purpose of this document, the following terms and definitions apply.
2.1
penetration
process by which a chemical moves through pores, apertures or essential openings in a material or finished
item of clothing
NOTE The apertures can be the result of mechanical damage.
2.2
permeation
process by which a chemical moves through a protective clothing material on a molecular level
NOTE Permeation involves the following:
a) sorption of the molecules of the chemical onto the contact surface (outer surface) of the material;
b) diffusion of the sorbed molecules into the material;
c) desorption of the molecules from the opposite (inner) surface of the material.
2.3
repellency
ability of a material to shed liquid that is applied to its surface
ISO 6530:2005(E)
3 Principle
A measured volume of a test liquid is applied in the form of a fine stream or jet to the surface of a clothing
material resting in an inclined gutter.
Determination of the respective proportions of the applied liquid which penetrate a test specimen and which
are repelled by its surface indicates the potential of the material for use in the described field of application.
4 Method
4.1 Apparatus
The apparatus, as assembled (see Figure 1), shall comprise the following:
 rigid transparent gutter, of semi-cylindrical shape, with an internal diameter (125 ± 5) mm, length

(105 ± 5) mm and an evenly distributed mass of (140 ± 7) g;
 hypodermic needle, bore (0,8 ± 0,02) mm; length is not critical but the pointed tip shall be removed and
the end ground flat;
 syringe or other leak-free attachment to the needle, capable of delivering (10 ± 0,5) cm of test liquid;
 motorized syringe-drive unit or a hydraulic pump or other pressurized system, to deliver the correct
volume of test liquid [(10 ± 0,5) cm ] in an unbroken stream or jet via the needle within (10 ± 1) s; manual
delivery or gravity shall not be used;
WARNING — Appropriate precautions applicable to the use of equipment under pressure and the
forceful discharge of liquid chemicals should be taken.
 mounting device, for maintaining the hypodermic needle and attachments in their required positions
(see Figure 1);
 small beaker;

 transparent film, resistant to the test liquid;
