EN ISO 8207:2026 is a CEN standard for hose assemblies used in gas welding, cutting and allied processes. It specifies performance and test requirements for assembled hose using rubber hose according to ISO 3821 up to and including nominal size 20,0. The standard applies to hose assemblies supplied in assembled condition and excludes high-pressure hose assemblies upstream of the pressure regulators.

What does EN ISO 8207:2026 specify?

EN ISO 8207:2026 sets requirements for the design, marking, performance and testing of hose assemblies for gas welding equipment. Its scope is limited to hose assemblies with rubber hose to ISO 3821 and to sizes up to nominal size 20,0, which matters in practice because the document is aimed at the hose sets actually delivered and used on equipment, not raw hose on its own.

The document is organized into scope, normative references, terms and definitions, construction, marking, performance requirements, and an informative annex. Annex A gives examples of kinking protection design.

What are the key requirements of EN ISO 8207:2026?

Construction and materials

EN ISO 8207:2026 requires hose assemblies to use hoses in accordance with ISO 3821 and suitable hose fittings. Parts that come into direct contact with the gas supply have to comply with ISO 9539, and hose mounting devices have to be corrosion resistant or protected against corrosion.

The document also prohibits greases or pastes in manufacture. In practice, that means the assembly has to be built cleanly, with compatible materials and without substances that could affect sealing, durability or gas quality.

Hose tail and secure attachment

EN ISO 8207:2026 requires the hose tail profile to avoid sharp edges that could damage the hose during assembly or use. The hose tail also has to provide enough mounting area for safe positioning of the hose mounting device.

The hose has to be securely fitted to the hose tail with a compatible hose mounting device that gives repeatable resistance to separation under axial load. Worm drive screw or similar detachable clips or clamps shall not be used. That matters because the joint has to stay secure under service loads, not only when new.

Marking

EN ISO 8207:2026 requires durable marking with the manufacturer name or trade mark and a reference to ISO 8207. The marking shall be on the end fitting or on a separate band fixed to the hose next to the end fitting.

A date code such as the last two digits of the year of assembly plus the month or week may also be marked. This helps traceability in production, storage and maintenance.

Performance tests

EN ISO 8207:2026 applies the tests in Clause 6 to type testing. Gas tightness is checked in accordance with ISO 9090, so the acceptance level is tied to the leakage limit in that standard.

Resistance to separation under pressure is tested for one minute at three times the maximum working pressure of the hose, at laboratory temperature, with a free length of 500 mm. The hose must not separate from the hose tail.

Resistance to separation under axial load is tested on an unpressurized hose assembly at laboratory temperature. The load depends on the nominal size and is given in Table 1, so users must select the correct test load for the size being assessed. The assembly must not separate, fracture, or lose gas tightness after the test.

What terms does EN ISO 8207:2026 define?

• hose assembly - a hose with a hose fitting attached to one or both ends.
• hose tail - the fitting part that carries the hose and provides the mounting area.
• hose fitting - the end fitting that forms part of the assembled hose connection.
• hose mounting device - the device used to secure the hose to the hose tail.
• kinking protection - an added feature that limits hose movement near the hose tail and helps prevent damage to the lining.
• type testing - the test set in Clause 6, used to verify the design of the hose assembly.

Who uses EN ISO 8207:2026?

EN ISO 8207:2026 is used by manufacturers of gas welding hose assemblies, suppliers of fittings and mounting devices, and test laboratories carrying out type tests. Quality managers use it to define acceptance checks for gas tightness, separation resistance and marking. Buyers and specifiers use it when selecting hose assemblies for welding, cutting and allied processes.

What changed in EN ISO 8207:2026 from the previous edition?

EN ISO 8207:2026 replaces ISO 8207:1996 and is technically revised. The main changes stated in the document are:

• the scope is clarified for rubber hose to ISO 3821 up to nominal size 20,0;
• a definition of assembled hose is added in Clause 3 and aligned with ISO 15296:2017;
• Clause 4 on construction is modified;
• the former operational criteria clause is moved into Clause 6;
• a new Clause 5 on marking is added;
• nominal sizes 12,5, 16,0 and 20,0 and their axial loads are added in Table 1;
• the former informative annex on hose tail dimensions is deleted;
• a new informative annex with examples of kinking protection design is added.

Which standards are used with EN ISO 8207:2026?

EN ISO 8207:2026 refers to these standards:

• ISO 3821 - the rubber hose used for the assemblies.
• ISO 8330 - the vocabulary source for hose and hose assembly terms.
• ISO 9090 - the gas tightness test method and leakage acceptance basis.
• ISO 9539 - the material requirements for parts in direct contact with the gas supply.

The document also names ISO 15296:2017 for vocabulary alignment and ISO/TR 28821 for hose connection listings.

What does the EN ISO 8207:2026 document contain?

EN ISO 8207:2026 contains construction rules, marking rules, and test methods with acceptance requirements for hose assemblies. It includes figures showing hose assembly configurations with permanent ferrule and permanent clamp, and Table 1 gives the axial loads used in the separation test for each nominal size.

Annex A gives example kinking protection designs for special applications. These contents support design, manufacture, type testing and verification of hose assemblies for gas welding, cutting and allied processes.
