Introduction
Compressed-air hoses are widely used in industrial plants, workshops, construction sites, mining operations, maintenance activities, pneumatic tools, and factory utility systems. Since these hoses carry compressed air under pressure, their quality, flexibility, pressure rating, reinforcement strength, temperature suitability, and marking must be checked carefully before use.
ISO 5774:2016 is an international standard titled Plastics hoses, Textile-reinforced types for compressed-air applications, Specification. The standard specifies requirements for four types of flexible thermoplastic hose, textile reinforced, for compressed-air applications in the temperature range from −10 °C to +60 °C.
The four hose types are classified by service duty and working pressure: light service, medium service, heavy service, and heavy service for mining use. These classifications help manufacturers, buyers, inspection agencies, and industrial users select and verify the correct hose type for the intended compressed-air application.
For organizations involved in hose manufacturing, industrial product supply, mining operations, compressed-air system maintenance, export, import, and quality control, ISO 5774:2016 provides a useful technical reference for product evaluation. TNV Inspection Division performs inspection activities as a neutral third-party inspection body, helping businesses verify hose condition, pressure rating, marking, packing, documentation, and inspection findings.
Key Objectives of the Standard
ISO 5774:2016 is designed to support reliable quality evaluation of textile-reinforced flexible thermoplastic hoses used for compressed-air applications. The standard helps organizations:
- Establish requirements for textile-reinforced thermoplastic compressed-air hoses.
- Classify hoses according to service duty and working pressure.
- Support safe selection of hoses for light, medium, heavy, and mining-related applications.

The Role of a Standardized Hose Specification
Using a standardized hose specification such as ISO 5774:2016 is important because compressed-air hoses may be used in conditions where pressure, bending, dragging, abrasion, temperature, and repeated handling can affect performance. Without a common product reference, buyers and suppliers may disagree about hose quality, pressure classification, or intended use.
- Ensures Product Quality: It helps verify whether the hose type, pressure rating, reinforcement, marking, and physical condition match the buyer’s requirement.
- Facilitates Fair Trade: A common standard reference gives manufacturers, buyers, exporters, importers, and inspection teams a shared basis for product acceptance.
- Protects Your Supply Chain: Proper hose inspection helps identify defects, incorrect marking, unsuitable pressure class, poor packing, or wrong product selection before dispatch or use.
- Supports Market Access: Hoses supported by structured inspection and testing records can create stronger confidence during buyer review, shipment approval, and industrial project supply.
Fundamentals of ISO 5774:2016 Compressed-Air Hose Requirements
The standard is based on key requirements that help evaluate textile-reinforced thermoplastic hoses for compressed-air applications.
- Textile-Reinforced Flexible Thermoplastic Hose: ISO 5774:2016 applies to flexible thermoplastic hoses that are textile reinforced and intended for compressed-air use. Textile reinforcement helps improve hose strength and pressure performance while maintaining flexibility for industrial use.
- Temperature Range: The standard covers hoses intended for use in the temperature range from −10 °C to +60 °C. This helps users understand the operating conditions for which the hose has been specified.
- Hose Service Classifications: ISO 5774:2016 classifies hoses into four service types: light service, medium service, heavy service, and heavy service for mining. This classification helps buyers select the right hose based on pressure and application severity.
- Working Pressure Ratings: The standard defines maximum working pressure ratings for the four hose types at 23 °C and 60 °C. ISO information lists these as 7 bar at 23 °C and 4.5 bar at 60 °C for light service, 10 bar at 23 °C and 6.5 bar at 60 °C for medium service, 16 bar at 23 °C and 11 bar at 60 °C for heavy service, and 25 bar at 23 °C and 13 bar at 60 °C for heavy service mining use.
Essential Criteria of ISO 5774:2016
ISO 5774:2016 supports a structured inspection approach for textile-reinforced thermoplastic compressed-air hoses.
- Product Identification: Before inspection begins, the hose type, size, pressure class, service category, batch number, manufacturer details, purchase order, and buyer requirements should be clearly identified.
- Hose Type Classification: The hose should be verified as light, medium, heavy, or heavy service for mining, depending on the specified application and working pressure requirement.
- Pressure Rating Review: The hose pressure rating should be checked against the applicable service type and temperature condition. This is important because pressure capacity changes depending on the hose classification and temperature.
- Material and Reinforcement Review: The hose should be checked as a textile-reinforced thermoplastic hose. Visible defects such as cracks, weak areas, deformation, exposed reinforcement, or surface damage should be reviewed during inspection.
- Dimensional and Visual Inspection: The hose size, length, wall condition, surface quality, flexibility, end condition, and visible workmanship should be reviewed according to buyer or project requirements.
- Marking and Traceability Review: Product marking should clearly support identification of hose type, size, pressure rating, batch details, manufacturer information, and other required details.
- Trained and Qualified Personnel: Inspection should be performed by trained personnel who understand industrial hose inspection, pressure rating review, visual condition checks, sampling, test coordination, and reporting.
- The Inspection Process
There is a clear process to follow: - Step 1 Product Identification: Record hose type, size, service class, batch details, and buyer requirements.
- Step 2 Visual Inspection: Check surface condition, reinforcement visibility, cracks, deformation, and workmanship.
- Step 3 Dimensional Review: Verify hose length, size, thickness-related details, and physical condition where required.
- Step 4 Pressure Rating Review: Check service classification and pressure rating against the required application.
- Step 5 Marking and Packing Review: Verify product marking, labels, packing, quantity, and shipment identification.
- Step 6 Reporting: Prepare a detailed inspection report with observations, findings, and final results.
Sealing, Labeling, and Reporting
When textile-reinforced compressed-air hoses are prepared for inspection, testing, buyer review, or shipment, they should be handled carefully to avoid kinking, crushing, contamination, deformation, or surface damage.
Every hose lot should be labeled properly for traceability. A detailed inspection report should include inspection date, location, hose type, size, quantity, batch number, pressure class, service type, marking details, packing condition, test reference where applicable, inspection observations, and final findings.
Clear reporting is important because hose inspection results may support buyer approval, supplier evaluation, shipment release, product acceptance, or technical quality review.
