Описание (английский):

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.

Overview

ISO 10807:1994 specifies design, material, manufacturing and testing requirements for corrugated flexible metallic hose assemblies used to protect electrical wires and cables in explosive atmospheres or fire-risk environments. The standard covers hoses intended for static protection or for cables moved infrequently (less than once per week). It includes instructions for use (Annex A), type-approval tests (Annex B) and marking/ordering details.

Key topics and requirements

Materials

Hose body: either topper alloy (topper content ≥ 94 %, per ISO 1634) or austenitic stainless steel (per ISO 683‑13).
End fittings: non-alloy steels (per ISO 4948) or austenitic stainless steel.
Braiding options: bronze wire (ISO 427) or austenitic stainless steel.

Manufacturing and joints

Permitted joining: braze welding, electric welding (MIG, MAG, TIG), microplasma (MP) or impulse welding.
Excluded: adhesive bonding and tin soldering.

Dimensions & performance

Nominal diameters, minimum bend radii and maximum lengths are defined (tables and figures in the standard).
Internal surfaces must be free from burrs/sharp edges to avoid cable damage.

Testing and type approval (Annex B)

Hydraulic test: each assembly tested at a minimum of 40 bar for at least 60 s with no leakage.
Flexural strength test: bending over shaping cylinders as specified; dimensional and visual inspections required.
Bending fatigue test: samples cycled (1 bar pressure, 40–120 cycles/min, 250 mm displacement); minimum cycles to failure not less than 10,000.
Approved hoses require certification and specific marking by the authorized agency.

Use guidance (Annex A)

Classification of locations: Class A (protected), Class B (exposed to corrosive agents) and Class C (highly corrosive). Material choices and additional protections are specified per class.

Marking & designation

Example format: TMFAE ISO 10807 DN40 - 800 - stainless steel - B (manufacturer, standard ref, DN, length, material, class).

Applications and who uses this standard

Protecting electrical cables in hazardous/explosive atmospheres (petrochemical plants, offshore installations, refineries, chemical plants).

Suitable for static cable protection or for cables moved infrequently.

Primary users: hose and cable assembly manufacturers, electrical/mechanical engineers, procurement officers, certification bodies, inspection agencies, and safety managers responsible for explosion-proof installations.
