EN 61386-1 Cable Conduit Tester | Rigid & Flexible Cable Management Systems | UnitedTest

EN 61386-1 defines general requirements and compliance tests for rigid and flexible cable management conduit systems. UnitedTest manufactures EN 61386-1 compliant test machines to verify mechanical, electrical and environmental protection performance of electrical cable conduits.


EN 61386-1 is the fundamental European standard covering general requirements and standardized testing procedures for all types of conduit systems designed for electrical cable management. This standard applies universally to both rigid and flexible conduit systems engineered to protect, route and organize electrical cables and cords across residential, commercial and industrial electrical installations.

It establishes comprehensive baseline performance criteria to ensure cable conduit systems deliver reliable multi-dimensional protection for electrical wiring, including robust mechanical resistance, stable electrical safety performance, and durable environmental protection against external environmental interference, physical damage and operational aging. Serving as the core general specification of the EN 61386 series, it lays the foundational testing and qualification rules for all subsequent part-specific conduit system standards.


Widely adopted for electrical product quality inspection, factory batch certification, and electrical engineering safety verification, EN 61386-1 guarantees the compliance and operational reliability of cable management systems. UnitedTest designs and manufactures high-precision EN 61386-1 professional testing equipment, fully meeting standard test requirements for mechanical property detection, electrical safety verification and environmental adaptability testing of rigid and flexible cable conduits.


Core Mechanical Test Methods and Testing equipment recommend of EN 61386-1: 

Compression (Crushing) Test      

Test sample: 

Sample Length: 200 ± 5 mm.

Quantity: Minimum 3 samples.

Test procedure: 

Measure initial outer diameter (D₀) of the specimen.

Place specimen centrally between compression plates; apply force at a certain speed that reaching the classification‑specific load in 30 ± 3 seconds.

Hold load for 60 s, then release.

Measure final outer diameter (D₁) and inspect for cracks, splits, or perforations.

Testing Machine: 

Universal testing machine (UTM) with compression plates (top platen 50*50mm). 

EN 61386-1 Conduit Cable Mechanical Tests

Impact TestDrop a standardized mass (hammer/ball) from a specified height onto conditioned specimens to deliver a defined impact energy; evaluate damage.
Sample info: 

Length: 200 ± 5 mm (straight sections).

Quantity: 12 samples per type/size

Test procedure: 

Mount specimen horizontally in the fixture; align impact point at the mid‑length crown (top of conduit).

Drop hammer from calibrated height to deliver classification‑specific energy (see table).

Perform 1 impact per specimen; test all 12 samples.

Inspect each specimen for cracks, breaks, or perforations.

EN 61386-1 Impact Test equipment for conduit: 

Electrical conduit impact testing machine is suitable for the impact test of a variety of plastic pipes and plastic corrugated pipes, to determine the stamping energy value required for pipe damage. 

EN 61386-1 Conduit Cable Mechanical Tests

Tensile test

Conduit systems tensile strength shall be tested as follows:

A sample of conduit and two conduit fittings or terminating conduit fittings are assembled in accordance with the manufacturer's instructions so that the overall length is approximately 300 mm. 

The assembly is subjected to a uniformly increasing tensile force reaching the certain value in (30 ± 3) s. This tensile force is then applied for 2 min ±10 s.

Where elongation occurs, the manufacturer shall be responsible for providing guidelines to assist the safe installation of the conduit system.

After the test, the conduit fittings or terminating conduit fittings shall remain properly assembled to the conduit, and there shall be no damage visible to normal or corrected vision without magnification.

Testing Machine: 

UnitedTest Universal testing machine (UTM) with compression plates (top platen 50*50mm). 


Test Applications

EN 61386‑1 mechanical tests apply to:

Rigid metallic conduits (steel, stainless steel).

Rigid non‑metallic conduits (PVC, fiberglass, PE).

Flexible/semi‑rigid conduits (corrugated PVC, metal‑clad, liquid‑tight).

Conduit fittings (couplings, elbows, adapters, boxes) used with the above.
