NATIONAL FOREWORD

This Indian Standard ( First Revision ) which is identical with ISO 8138: 1998 ‘Hydraulic fluidpower — Single rod cylinders, 16 MPa ( 160 bar ) compact series — Port dimensions’ issued by theInternational Organization for Standardization ( ISO ) was adopted by the Bureau of Indian Standardson the recommendations of the Hydraulic Fluid Power Systems Sectional Committee and approval ofthe Medical Instruments, General and Production Engineering Division Council.

This standard was first published in 1991 by adopting ISO 8138:1986 ‘Hydraulic fluid power — Singlerod cylinders, 160 bar ( 16 MPa ) compact series — Port dimensions’. The ISO Standard has sincebeen revised as ISO 8138:1998. To align the standard with international practices, the sectionalcommittee, dealing with the subject, decided to revise IS 13103:1991 by adopting ISO 8138:1998 asIndian Standard under dual numbering system.

In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressurewithin an enclosed circuit. One component of such systems is the fluid power cylinder. This is adevice which converts power into linear mechanical force and motion. It consists of a movable element,that is, a piston and piston rod, operating within a cylindrical bore.

The text of the ISO Standard has been approved as suitable for publication as an Indian Standardwithout deviations. Certain conventions 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 beread as ‘Indian Standard’.

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

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their places are listedbelow along with their degree of equivalence for the editions indicated:

1 Scope

This International Standard establishes port dimensional) for 16 MPa (160 bar2)) compact series cylinders asrequired for interchangeability of commonly used hydraulic cylinders.

NOTE — This International Standard allows manufacturers of hydraulic equipment, freedom in design of metric cylinders; itdoes not restrict technical development but provides basic guidelines.

The compact series dimensions are most applicable to square head cylinders.

This International Standard will be incorporated into the next edition of ISO 6020-2.
