A compressed-air hose can look perfectly sound from the outside and still be the weakest point in a pneumatic system. Pressure cycling, bending, heat, ageing, and poor reinforcement can turn a small defect into leakage, hose separation, or sudden failure. ISO 5774:2016 gives manufacturers, buyers, and inspectors a common specification for judging whether textile-reinforced plastics hoses intended for compressed air are fit for that job.
This page explains what ISO 5774:2016 is, the hose characteristics it addresses, and how TNV Inspection Division uses it as an inspection reference. TNV is a UAF accredited inspection body operating under ISO/IEC 17020:2012.
What Is ISO 5774:2016?
ISO 5774:2016 is the international standard titled Plastics hoses — Textile-reinforced types for compressed-air applications — Specification. It sets requirements for flexible plastics hoses reinforced with textile materials and designed to carry compressed air.
The standard is a product specification. It is concerned with whether the hose has the construction, dimensions, physical properties, pressure performance, durability, and marking needed for its intended service. It gives manufacturers a design and production benchmark, while giving purchasers and inspectors a consistent basis for acceptance.
What ISO 5774 Covers
The standard brings the main performance expectations for compressed-air plastics hose into one specification. Depending on the agreed product type and inspection scope, the evidence reviewed can include:
- Construction and materials, including the plastics lining or cover and the textile reinforcement that carries pressure loads.
- Nominal bore, wall thickness, outside diameter, and dimensional tolerances.
- Pressure performance, including resistance to proof pressure and burst pressure.
- Adhesion between the hose layers so that the lining, reinforcement, and cover do not separate in service.
- Flexibility and behaviour when bent, including checks for kinking, cracking, or unacceptable deformation.
- Performance after ageing or other conditioning relevant to expected service.
- Visual quality, workmanship, identification, and product marking.
- Sampling, test records, and reporting needed to demonstrate that production remains consistent.
The standard does not remove the need to match a hose to the actual operating system. Pressure, temperature, environment, fittings, movement, and exposure to oils or chemicals still need to be considered when the hose is selected.
How TNV Uses ISO 5774 as the Reference Standard
A hose inspection needs more than a visual check. ISO 5774 provides the technical benchmark against which the product, test evidence, and manufacturing controls can be reviewed. As a UAF accredited inspection body under ISO/IEC 17020, TNV Inspection Division can use the standard as agreed inspection criteria for textile-reinforced plastics hoses intended for compressed-air service.
Our role is inspection, not product certification. We independently assess the items and evidence included in the agreed scope, record what we find, and report whether the inspected product or batch meets the stated acceptance criteria at the time of inspection.
How We Inspect Hoses Against ISO 5774
An ISO 5774 inspection can be arranged at a manufacturing plant, warehouse, supplier location, or another agreed site. The exact activities depend on the order, inspection level, and available testing facilities, but typically include the following.
- Document and specification review: We check purchase requirements, drawings, datasheets, material declarations, and the applicable edition of the standard.
- Visual and workmanship inspection: We look for surface defects, contamination, reinforcement irregularities, damage, poor finishing, and other visible issues.
- Dimensional verification: We check bore, outside diameter, wall thickness, length, and tolerances using suitable calibrated equipment.
- Construction and marking checks: We verify hose type, reinforcement, identification, traceability, and required markings against the approved specification.
- Test witnessing or record review: Where included, we witness relevant tests or review laboratory results for pressure, burst, adhesion, flexibility, ageing, or other specified properties.
- Sampling and traceability: We confirm that samples and inspected lots can be linked to production records, batch numbers, and test evidence.
- Reporting: We issue a clear report identifying the scope, samples, checks performed, results, deviations, and supporting evidence.
Where laboratory testing falls outside the agreed inspection activity, testing is carried out by a competent laboratory and the resulting evidence is reviewed as part of the inspection scope.
Our UAF Accreditation Explained
TNV Global Limited (TNV) is accredited by the United Accreditation Foundation (UAF) for inspection under ISO/IEC 17020:2012 — Conformity assessment — Requirements for the operation of various types of bodies performing inspection. We maintain that accreditation through regular surveillance and witnessed inspections.
UAF participates in international recognition arrangements, and our inspection activities support customers working across Europe, the Americas, the Middle East, Africa, and Asia. The practical value is that the inspection is performed within a recognised framework for competence, impartiality, consistency, and control of inspection records.
What Our Accreditation Means for You
Your inspection is carried out by an independent body working to defined procedures. The scope, standard, inspection stage, sampling method, and acceptance criteria are agreed before work starts. Inspectors are selected for relevant technical competence, equipment is controlled, findings are supported by evidence, and reports are reviewed before release.
That gives buyers, manufacturers, and project teams a clearer basis for making release, acceptance, corrective-action, or supplier decisions.
Why Does ISO 5774 Matter for Your Business?
Compressed air is widely used for tools, controls, cleaning, automation, and industrial processing. A hose failure can stop production, waste energy, damage equipment, or expose people to a whipping or bursting hose. ISO 5774 helps reduce that uncertainty by defining what a suitable textile-reinforced plastics hose should demonstrate before it enters service.
For manufacturers, the standard supports consistent design, production, and batch testing. For purchasers, it makes technical requirements clearer and supplier offers easier to compare. For end users, it provides a stronger basis for selecting hoses that match the intended pneumatic duty. Independent inspection adds a separate check that the supplied product and supporting records correspond to what was ordered.
Who Should Use ISO 5774?
- Manufacturers of textile-reinforced plastics hoses.
- Compressed-air equipment and pneumatic-system suppliers.
- Industrial plants using flexible compressed-air distribution lines.
- Engineering, procurement, and construction contractors.
- Distributors and importers of industrial hoses.
- Quality, purchasing, maintenance, and supplier-development teams.
- Independent laboratories and inspection bodies involved in hose verification.
How to Arrange an ISO 5774 Inspection with TNV
- Share your requirement. Reach us by website, email, phone, or WhatsApp and send the hose specification, quantity, inspection location, purchase order, and the stage at which inspection is needed. We review the scope and issue a proposal covering method, timing, and cost.
- We plan the inspection. We agree the inspection level, samples, acceptance criteria, documents, tests, and reporting requirements, then assign an inspector with relevant product experience.
- We inspect. The inspector reviews the hose, dimensions, workmanship, markings, traceability, and available test evidence. Specified tests can be witnessed where facilities and scope allow.
- We report. You receive a detailed inspection report identifying what was examined, the results, any deviations, and the evidence supporting the findings.
- We follow up. We answer questions, review corrective evidence where agreed, and arrange reinspection or additional witnessing when required.
