Overview
ISO 7751:2016 is an international standard developed by the International Organization for Standardization (ISO) that defines the required ratios of proof pressure and minimum burst pressure relative to the maximum working pressure for rubber and plastics hoses and hose assemblies. This third edition, published in November 2016, updates and replaces previous versions, introducing new categories such as hoses used for delivery of cement, concrete, plaster, and grout. The document assures safety and reliability in hose design and testing by setting standardized benchmark ratios applicable across various hose services.
Key Topics
Proof Pressure Ratio
The ratio of proof pressure to maximum working pressure indicates the pressure level at which hoses must undergo testing to confirm structural integrity without any failure. This ratio is crucial to verify hose durability under stress conditions.Minimum Burst Pressure Ratio
This ratio defines the minimum pressure that a hose assembly must withstand before rupture. It represents the safety threshold required to prevent catastrophic failure during operation.Categories of Hose Service
ISO 7751:2016 categorizes hoses by the type of service they are intended for, establishing tailored proof and burst pressure ratios, such as:- Water hoses (≤ 1 MPa)
- Hoses for liquids, solids suspended in liquids, or air (≥ 1 MPa)
- Compressed air and other gases
- Media that vaporize under pressure reduction
- Steam hoses
- Jetting hoses
- Hoses for cement, concrete, plaster, and grout delivery
Testing Methods
The standard mandates that hydrostatic testing of hoses for proof and burst pressures be performed according to ISO 1402, ensuring consistency and reliability in test procedures.
Applications
ISO 7751:2016 serves as a critical guideline for manufacturers, testers, and end-users involved with rubber and plastic hose assemblies in industries such as construction, manufacturing, mining, and fluid transport systems. The standard supports:
Quality Assurance
Ensuring hoses meet or exceed safety margins during design and production, minimizing risk of failure during use.Safety Compliance
Guiding testing protocols to validate pressure capabilities, promoting safe operation in high-pressure applications.Design Optimization
Allowing engineers to select appropriate materials and build specifications based on required proof and burst pressure ratios aligned with maximum working pressures.Standardization Across Markets
Facilitating international trade and compatibility by harmonizing testing criteria and pressure ratios globally, reducing technical barriers.
Related Standards
To complement ISO 7751:2016, the following standards are essential references for professionals working with hoses and hose assemblies:
ISO 1402: Rubber and plastics hoses and hose assemblies - Hydrostatic testing
Outlines the precise procedures for conducting pressure tests on hoses.ISO 8330: Rubber and plastics hoses and hose assemblies - Vocabulary
Provides terms and definitions relevant to hose technology to ensure uniform understanding.ISO 7741 Series: Hose assemblies for specific applications
Includes detailed requirements for product-specific hose assemblies aligned with safety standards.
Summary
ISO 7751:2016 is a foundational standard that defines critical pressure ratios - proof pressure and burst pressure in relation to maximum working pressure - for rubber and plastics hoses and hose assemblies. By prescribing these ratios and linking them to clearly defined service categories and testing procedures, the standard enhances the reliability, safety, and performance of hoses used worldwide in numerous industrial applications. Manufacturers and engineers adopting ISO 7751:2016 benefit from clarified safety margins and testing consistency, facilitating superior hose design and international standards compliance.

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).
