NATIONAL FOREWORD

This Indian Standard (Fifth Revision) which is identical with ISO 2398 : 2006 ‘Rubber hoses, textile-reinforced, for compressed air - Specification’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Rubber and Rubber Products Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.

This standard was first published in 1953 and subsequently revised in 1964, 1968, 1980 and 1987. The second revision was amalgamated revision of IS 446 : 1964 ‘Specification for air hose of rubber, light duty, with woven reinforcements (revised)’ and IS 3557 : 1965 ‘Specification for air hose of rubber, heavy duty, with woven reinforcements’ covering both light and heavy duty hoses. Third revision was amalgamated revision of IS 446 : 1968 ‘Specification for air hose of rubber with woven textile reinforcements (second revision)’ and IS 911 : 1968 ‘Specification for air hose of rubber with braided textile reinforcement (second revision)’. In fourth revision, specific materials and design features were not specified and only performance requirements were specified to allow future technological developments. Further, the requirements for pressure, accelerated ageing and adhesion were modified.

The fifth revision has been undertaken to align it with the latest version of ISO 2398 : 2006 (last reviewed in 2009) in dual numbering system to make pace with latest developments that have taken place at international level. In this revision, the title of ISO standard has been retained, as it is an identical standard.

This standard also makes a reference to the Packing and BIS Certification Marking of the product. Details of which are given in National Annex A.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
