ISO/TC 5/SC 11 - Metal hoses and expansion joints

This document defines current terms concerning metal hoses, metal hose assemblies and component parts. This document applies to: a) stripwound metal hoses and hose assemblies; b) corrugated metal hoses and hose assemblies. NOTE 1 These hoses can be used braided, covered or lined. NOTE 2 Equivalent terms in English, French, German and Dutch are given in Annex A.

ISO 10380:2012 specifies the minimum requirements for the design, manufacture, testing and installation of corrugated metal hose and metal hose assemblies.

ISO 15465:2004 specifies the requirements for the design, manufacture and testing of four principal types of stripwound metal hose and hose assemblies, of which only one type is for pressure applications. The four are: single overlap, unpacked and packed; double overlap, unpacked and packed, the last of these having maximum permissible pressures of up to 40 bar. These hoses and hose assemblies may be supplied in nominal sizes from DN 6 to DN 500 and may operate at temperatures up to 600 °C dependent on materials of construction.

ISO 10806:2003 specifies the characteristics of fittings for corrugated metal hose conforming with the requirements of ISO 10380. ISO 10806:2003 is also valid for other fittings provided they meet the material, design, assembly and test requirements specified herein.

Specifies the design characteristics of corrugated flexible metallic hose which can be used to protect electrical wire and cable in explosive atmospheres or atmospheres where there is a risk of fire. These hoses can be used as static protection or for the protection of cables moved infrequently, occasionally, or less than once week. Also provides instructions for the use of these hoses and the tests required for type approval.

ISO 10380:2002 specifies the requirements for the design, manufacture and testing of corrugated metal hoses and hose assemblies for general purposes. It also specifies sizes from DN 4 to DN 300, pressures from PN 0,5 to PN 250, pressure derating factors for elevated temperatures, two methods of construction and three types of flexibility of hose assembly.

ISO 15348 specifies the terminology and the general rules for the design, manufacture, control and type testing of metal expansion joints incorporating corrugated bellows. It applies to metal expansion joints equipped with one or more corrugated bellows of circular cross-section.

Cancels and replaces the first edition (1985). Specifies the diameters of double overlap leakproof flexible metal hoses with packing, of circular section, in austenitic stainless steel. The packing should not be asbestos. Suitable materials include, for example, cotton, fibre-glass, nylon, Kevlar, polyamide, polyester etc. Applies to flexible metal hoses, without external coating, used under pressure, without leakage, at temperatures between -20 °C and a maximum of 230 °C.

Cancels and replaces the first edition (1985). Specifies the diameters of double overlap leakproof flexible metal hoses with packing, of circular section, in protected carbon steel. The packing should not be asbestos. Suitable materials include, for example, cotton, fibre-glass, nylon, Kevlar, polyamide, polyester etc. Applies to flexible metal hoses, without external coating, used under pressure, without leakage, at temperatures between -20 °C and a maximum of 230 °C.

Specifies the diameters of the flexible metal hoses in accordance with ISO 7657 and tested in accordance with ISO 7658 without external coating (as defined in ISO 7369:1983, 4.1.10), used under low pressure, with permissible leakage, at temperatures between - 20 °C and a maximum of 230 °C. The packing should not be asbestos. Suitable materials include cotton, fibre-glass, nylon, Kevlar, polyamide, polyester, etc.

Defines the conditions (materials, performance characteristics, temperature-related requirements) to be met for the flexible metal hoses, without coating (as defined in ISO 7369:1983, 4.1.10). The metal hoses defined are manufactured from helically wound preformed strip, generally with a right-hand lead where the turns, with or without packing, are connected together by single or double overlapping. Flexibility is achieved by adjacent turns sliding on each other.

Specifies the design characteristics of non-alloyed and stainless steel fittings for corrugated flexible metallic hose in accordance with the requirements of ISO 10380. These fittings are suitable for the majority of applications. The characteristics of other types of fittings used will be the subject of an agreement between the purchaser and the manufacturer.

Specifies the requirements for the design, manufacture and testing. Also specifies nominal sizes from DN 6 to DN 300, nominal pressures from PN 2,5 to PN 250, two types of construction and two types of flexibility of hose assembly. The corrugated hose assemblies specified are suitable for the majority of possible applications. They are however not designed for applications involving axial compression or extension, or external pressure.

Specifies diameters of hoses and gives requirements to be verified in accordance with ISO 7658. Applies to uncoated hoses. A figure illustrates the meaning of the text. Gives an example of designation. The table includes nominal size from DN 6 up to and including DN 300.

Specifies diameters of hoses and gives requirements to be verified in accordance with ISO 7658. Applies to uncoated hoses under low pressure with permissible leakage, at temperatures from -20 to +600 C. A figure illustrates the meaning of the text. Gives an example of designation. The table includes nominal sizes from DN 6 up to and including DN 500.

Specifies diameters of hoses and given requirements to be verified in accordance with ISO 7658. Applies to uncoated hoses used under low pressure with permissible leakage, at temperatures from -20 to +60 C. A figure illustrates the meaning of the text. Gives an example of designation. The table includes nominal sizes from DN 6 up to and including DN 500.

Specifies diameters of hoses and given requirements to be verified in accordance with ISO 7658. Applies to uncoated hoses used under low pressure with permissible leakage, at temperatures from -20 to +600 C. A figure illustrates the meaning of the text. Gives an example of designation. The table includes nominal sizes from DN 12 up to and including DN 500.

Specifies test methods necessary to check characteristics of hoses as defined in the specific product standards for each hose type. It also specifies complementary tests, the results of which can be essential to purpose users.
