Rubber and plastics hoses and hose assemblies, wire or textile reinforced types with working pressure equal or above 70 MPa (700 bar) — Specification

This document specifies requirements for two types of reinforced hoses and hose assemblies of nominal size from 3,2 to 25, dependent on relation of minimum burst pressure to maximum working pressure. Each type is divided into classes dependent on maximum working pressure. They are suitable for use with: — oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from −40 °C to +100 °C; — water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from 0 °C to +70 °C; — water at temperatures ranging from 0 °C to +70 °C. Such hoses and hose assemblies are intended to be used for: — water jetting and water blasting applications; — hydraulic applications. This document does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies. NOTE 1 It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used. NOTE 2 For hydraulic jacks with manually driven pumps, hoses and hose assemblies per ISO 16301 can be used.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

4 List of significant hazards
4.1 General
This clause contains some of the significant hazards, hazardous situations and events, as far as they are
dealt with in this document, identified by risk assessment as significant for this type of machinery and
which require action to eliminate or reduce the risk.
4.2 Hazards due to bursting or leaking of hoses
Hazards can occur when a hose bursts or leaks. The escaping stream of liquid can cause physical
damage and a sudden repositioning of the hose line in a dangerous manner (whip).
4.3 Hazards due to failure of connectors
Hazards can occur when a connector fails. The escaping stream of liquid can cause physical damage
and a sudden repositioning of the hose line in a dangerous manner (whip).
4.4 Hazards due to errors by the operator
Hazards can occur if the operator uses incompatible substances or incompatible components. Hazards
can also occur if the operator exceeds the limits of use specified by the manufacturer (e.g. too high
pressure, too high tensile stress), also pinhole caused by kink may result in a significant injury.
4.5 Hazards due to change in length of hose assembly
Hazardous situations occur when there is a sudden change of pressure in the hose line causing a change
in length resulting in the operators losing their firm hold.
