Foreword

This standard is equivalent to international standards ISO 14557:2002 "Fire Hose Rubber and plastic hoses and hose assemblies attract" (In English).

This standard is equivalent translation ISO 14557:2002.

GB/T 7528 is a modified adoption of international standards ISO 8330 Chapter 2 of this standard references 1998, covered by this standard vocabulary and the National International standards.

d) adding a reference, as in the notes to 6.6 GB/T 18424-2001 is cited as an information content, so its columns the reference.

The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E is a normative appendix, Appendix F for the informative appendix.

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Rubber and rubber products hose Standardization Technical Committee Technical Committee (SAC/TC35/SC1) centralized.

Introduction

This standard applies to manual water supply is not pressurized fire hose to pump attract.

GB/T 24144-2009/ISO 14557:2002 Fire Hose Rubber and plastic hoses and hose assemblies attract

1 Scope

This standard specifies the requirements and test methods for fire rubber and plastic hoses attract.

Note 1. All the pressure is expressed in MPa. 1MPa = 10bar.

This standard also specifies requirements for hose assemblies. Hose assemblies have been fitted with means of hose fittings, hose assembly is made Factory made (see Chapter 8).

A type (rubber) hose is suitable for -20 °C lowest temperature, B-type (thermoplastics) hose is suitable for a minimum temperature of -10 °C.

Note 2. The hose lower than the predetermined temperature can be used in manufacturing supply agreement with the purchaser. In this case, the low temperature flexibility tests (See 6.3) should be carried out at a predetermined temperature.
