ISO 16301:2017

Rubber and plastics hoses and hose assemblies, wire- or textile-reinforced, for manually operated hydraulic jacks — Specification

ISO 16301 specifies the requirements for three classes of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 25. The hoses and hose assemblies are used in hydraulic jack applications with manually operated hand pumps. They are suitable for use with hydraulic fluids HH, HL, HM, HR and HV at temperature ranging from −40 °C to +55 °C. For tools that require heavy duty services such as a rescue tool, ISO 19718[3] applies. ISO 16301 does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The maximum working pressure of hose assemblies is regulated by the lowest maximum working pressure of the components. 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 There are two International Standards for hoses for hydraulic jacks and tool applications, i.e. ISO 16301 and ISO 19718. The comparison table is given in Annex A. NOTE 3 The classification of HH, HL, HM, HR and HV is found in ISO 6743-4[2].

Overview

ISO 16301:2017 sets out the international requirements for rubber and plastics hoses and hose assemblies, specifically designed for use with manually operated hydraulic jacks. Covering both wire-reinforced and textile-reinforced hoses, this standard applies to hose assemblies with nominal sizes from 5 to 25 and is focused on ensuring performance safety and reliability in critical hydraulic jack applications. ISO 16301 is established by the International Organization for Standardization (ISO) and is critical for manufacturers, suppliers, and users of hydraulic equipment who require consistent product quality and safety assurance.

Key Topics

• Scope and Applicability: Specifies three classes of hose and hose assemblies for manual hydraulic hand pump jacks, covering nominal sizes 5 to 25.
• Types of Reinforcement: Covers hoses reinforced with either steel wire or textile materials, suitable for a range of hydraulic fluid types (HH, HL, HM, HR, HV) and operational temperatures from −40 °C to +55 °C.
• Performance Criteria: Defines key performance requirements such as maximum working pressure, proof pressure, minimum burst pressure, change in length, bend radius, and resistance to oil, ozone, and cold bending.
• Hazard Management: Addresses hazards related to bursting, leaking, connector failure, operator error, and sudden changes in hose assembly length to promote occupational health and safety.
• Classification and Grades: Outlines three classes based on maximum working pressure, and grades based on electrical conductivity requirements.
• Testing and Quality Control: Specifies type tests, routine tests, and recommended production test frequencies for dimensions, material composition, performance, and marking.
• Marking: Requires clear, standardized marking of hoses and hose assemblies for identification, traceability, and compliance with ISO 16301.
• Packaging and Storage: Recommends proper packaging and storage practices to preserve hose integrity and performance.

Applications

• Hydraulic Jacks: Essential for manually operated hydraulic hand pumps used in automotive, industrial, and equipment maintenance operations.
• Light-duty Hydraulic Equipment: Suitable for applications requiring reliable fluid transfer under high pressure, such as hydraulic presses and torque wrenches.
• Safety-focused Operations: Provides guidelines ensuring hoses and assemblies are resistant to oil, weather, abrasion, and temperature fluctuations, supporting safe use in demanding environments.
• Manufacturing and Quality Assurance: Used by hose manufacturers and suppliers in product design, batch testing, and certification processes to meet international standards and customer requirements.

Related Standards

• ISO 19718 - Specification for hoses and hose assemblies for heavy-duty hydraulic tool applications (e.g., rescue tools).
• ISO 6743-4 - Classification of hydraulic fluids (HH, HL, HM, HR, HV).
• ISO 1402 - Hydrostatic testing of rubber and plastics hoses and hose assemblies.
• ISO 1817 - Determination of the effect of liquids on rubber, vulcanized or thermoplastic.
• ISO 6803 - Hydraulic-pressure impulse test for hoses and assemblies.
• ISO 7326 - Assessment of ozone resistance for hoses.
• ISO 8330/ISO 8331 - Hose vocabulary and guidelines for selection, storage, and maintenance.
• ISO 10619-1/2 - Measurement of flexibility and stiffness at ambient and sub-ambient temperatures.

ISO 16301:2017 enables manufacturers, suppliers, and end users worldwide to achieve consistency, safety, and quality in wire- or textile-reinforced hydraulic hoses and assemblies for manually operated jacks. By complying with this standard, organizations can minimize the risk of failure, ensure compatibility with various hydraulic fluids, and support the safe, effective operation of critical hydraulic equipment.

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 personal injury
or property damage.

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 also a sudden repositioning of the hose assembly in a dangerous manner (whip).
Figure 2 — Hazards due to failure of connectors
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 might result in a significant injury.
