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 reprented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cloly 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. Publi
cation 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 22958 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing and water resistance tests.

Introduction
This rain test is more suitable for measuring relatively low amounts of water penetrating highly water resistant fabric. ISO 9865, Textiles — Determination of water repellency of fabrics by the Bundesmann rain-shower test, is not very accurate for measuring water resistance (penetration) when testing the latest tightly woven or lightly coated fabrics in the market today.
