IS 11845 : Part 3 : 1994/ISO 5784-3 : 1989 Fluid logic circuits for fluid power systems - Part 3:Symbols for logic sequences and related functions

National Foreword

This Indian Standard which is identical with ISO 5784-3 : 1989`Fluid power systems and components - Fluid logic circuits - Part3: Symbols for logic sequencers and related functions issued bythe International Organization for Standardization (ISO), wasadopted by the Bureau of Indian Standards on the recommendations ofthe Basic Fluid Power Sectional Committee and approval of theProduction Engineering Division Council.

IS 11845 was first published in 1986 based on ISO/DIS 5784/1.This International Standard has been finalized as ISO Standard inthe following three parts:1

ISO 5784/1 : 1988 Fluid power systems and components- Fluid logiccircuits - Part 1: Symbols for binary logic andrelated functions

ISO 5784/2 : 1989 Fluid power systems and components- Fluid logiccircuits - Part 2: Symbols for supply and exhausts asrelated to logic symbols

ISO 5784/3 : 1988 Fluid power systems and components- Fluid logiccircuits - Part 3: Symbols for logic sequencers andrelated functions

To align with the international practices, the SectionalCommittee, PE 14 has decided to revise IS 11845 : 1986 by adoptingthe above ISO standards as dual number standards in the followingthree parts:

IS 11845 : Part 1 : 1994/ISO 5784-1 : 1988 Fluid logic circuits for fluid power systems : Part 1 Symbols for binary logic and related functions

IS 11845 : Part 2 : 1994/ISO 5784-2:1988 Fluid logic circuits for fluid power systems : Part 2 Symbols for supply and exhausts as related to logic symbols

IS 11845 : Part 3 : 1994/ISO 5784-3:1988 Fluid logic circuits for fluid power systems : Part 3 Symbols for logic sequencers and related functions
