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

EN ISO 10807:1996 (ISO 10807:1994) specifies design, materials, testing and marking requirements for corrugated flexible metallic hose assemblies used to protect electrical cables in explosive atmospheres or where there is a fire risk. The standard covers hoses used as static protection or for cables moved infrequently (occasionally or less than once per week), and includes instructions for use and the type-approval tests required for certification.

Key topics and technical requirements

Scope and usage: Protection of electrical wire and cable in explosive or fire-risk atmospheres; suitable for static or infrequently moved cables.

Materials:

Metallic hose: copper alloy (≥94% copper) or austenitic stainless steel.
End fittings: non-alloy steel or austenitic stainless steel.
Braiding: bronze wire or austenitic stainless steel.

Manufacturing and joints: Acceptable joining methods include brazing and electric welding (MIG, MAG, TIG), microplasma and impulse welding. Adhesive bonding and tin soldering are excluded.

Dimensions & performance: Internal diameters, minimum bend radii and performance classes are defined (see standard’s tables for DN-specific values). End fittings, thread types and total hose lengths are specified.

Inspection & testing:

Manufacturer inspections: dimensional, visual and hydraulic testing.
Hydraulic test: minimum 40 bar for at least 60 seconds with no leakage.
Type-approval tests (Annex B): flexural strength and bending fatigue tests using specified sample sizes and test conditions. Bending fatigue requires a minimum of 10,000 cycles; fatigue test pressure typically 1 bar, with controlled bending amplitude and rate.

Finish & marking:

Internal surfaces must be free of burrs and sharp edges.
Marking must include manufacturer, reference to EN ISO 10807, year of production and class of location.

Applications and who uses this standard

Electrical engineers and specifiers designing installations in hazardous areas (ATEX/explosion-risk zones).

Manufacturers of corrugated flexible metallic hose assemblies and end fittings for cable protection.

Certification bodies and testing laboratories performing type approval and conformity testing.

Installers, maintenance teams and safety assessors specifying appropriate cable protection for industrial, offshore and corrosive environments.
