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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Protective clothing — Protection against rain — Test method for
ready-made garments against high-energy droplets from above
1 Scope
This document specifies a test method for determining the liquid tightness of clothing for protection against
rain, using a static manikin exposed to large amount of high energy droplets from above. It is applicable to
the testing of jackets, trousers, coats and one- or two-piece suits.
This document is not applicable to the testing of garments for resistance to other weather conditions, e.g.
snow, hail-, or strong winds.
NOTE For general background of the rain simulation, see Annex A.

4 Principle
A manikin with the shape and size of an adult person wearing long underwear made of absorbent fabric is
dressed in the protective garment to be tested and exposed to large amount of high energy droplets from
above for a specific period. After the exposure the underwear and the inner side of the protective garment
are visually inspected for wet areas. In addition, sensors on the manikin may be used in order to detect the
timing of water ingress at individual sites.
5 Apparatus
5.1 Tower device, (as shown in Figure 1) comprising a circular tub at least 1 000 mm in diameter
supported at least 5 000 mm above the floor and supplied with water from an inflow pipe. The base of the
tub shall be fitted with approximately 682 nozzles with a hole diameter of 0,6 mm placed at 34 mm centres
to deliver water droplets over a circular area with a diameter of 932 mm at a density of approximately
1 000 droplets/m . The tub shall have an overflow pipe placed to maintain a water depth of (45 ± 5) mm in
