Foreword

This revised standard adopts ISO 5249. 1988 "Textile machinery and accessories dyeing machine guide roller main dimensions" (in English).

This standard is based on ISO 5249. 1988 to redraft the provisions relating to technical differences involved in the margin by a vertical line identification, these technical differences are.

--- Table 1, Table 2 adds an outer diameter of 180mm;

--- Guide roller permissible radial runout full requirements, increased to "0.4/1000";

--- Increasing the fabric guide roll surface quality requirements, see 5.3;

--- Increased Chapter 7, "Test Method";

--- Added Appendix B "installation center distance" and Appendix C "Test Method." for ease of use, this standard made the following editorial changes, which the structure of the text according to GB/T 1.1-2000 "Standardization Guide - Part 1. Standard structure and write rules "for editing. And ISO 5249. 1988 compared to the main changes are as follows.
