EN 124-5 Testing for Manhole & Gully Tops

2026-05-01 · 2 min read · By TCR Newsroom

TCR Engineering in Navi Mumbai conducts EN 124-5 tests including load, deflection, tilt, fatigue (100,000 cycles), and permanent set for manhole covers.

Article

TCR Engineering tests manhole covers and gully tops to BS EN 124 at its Mahape laboratory in Navi Mumbai: load bearing capacity, permanent set and tilt to BS EN 124-1, and deflection and fatigue of composite gully and manhole tops up to 900 mm to BS EN 124-5. The tests are reported outside the scope of NABL certificate NABLT0726MH18640.

  • Load classes: A15, B125, C250, D400, E600 and F900
  • Indian cover standards: IS 1726 for cast iron and IS 12592 for precast concrete covers
  • Fatigue: compression to compression at room temperature, up to 100,000 cycles or until fracture
  • From the customer: the cover and frame assembly, prepared as BS EN 124 Parts 1 and 5 require

TCR Engineering is proud to announce that its current-generation laboratory located in Mahape, Navi Mumbai now offers comprehensive testing of manhole covers and gully tops in full compliance with EN 124 Part 5, including associated requirements from EN 124 Part 1.

TCR Engineering in Navi Mumbai conducts EN 124-5 tests including load, deflection, tilt, fatigue (100,000 cycles), and permanent set for manhole covers.

Our laboratory is fully equipped to test cast iron, composite, and other materials for use in access covers and frames across all load-bearing classes (A15 to F900) as defined under BS EN 124.

Scope of Testing Services:

We perform the following BS EN 124-compliant tests at our facility:

  • Deflection Under Load

Standard: BS EN 124-5

Measures the displacement of the cover under a specific test load.

  • Test Load Bearing Capacity

Standard: BS EN 124-1 Annex B

Determines the strength of the sample under static loading conditions.

  • Tilt Test

Standard: BS EN 124-1 Annex D

Checks stability and proper seating of the manhole/gully top under tilt conditions.

  • Permanent Set Test

Standard: BS EN 124-1 Annex A

Evaluates any permanent deformation after loading.

  • Resistance to Fatigue Test

Standard: BS EN 124-5

Conducted in Compression–Compression mode at room temperature.

- Up to 100,000 cycles or until fracture, whichever occurs first.

- Additional cycles beyond that run in steps of 10,000 where the specification calls for them.

- Customers must supply the Fatigue Test Assembly (cover plus frame).

Capacity:

  • Fatigue testing of manhole/gully tops up to 900 mm diameter is available.
  • All samples must comply with the preparation requirements of BS EN 124 Part 1 & 5.

Why Choose TCR Engineering?

FAQ

Which standard applies to manhole covers in India: IS 1726, IS 12592 or BS EN 124?

The cover material and the specification it is bought against decide the standard. Cast iron covers are tested to IS 1726 and precast concrete covers to IS 12592, while BS EN 124 applies where the specification is European or international, with Part 5 adding a fatigue test for composite tops. TCR Engineering tests to all three.

Is BS EN 124 testing at TCR Engineering NABL accredited?

No. BS EN 124, IS 1726 and IS 12592 are not on NABL certificate NABLT0726MH18640, so reports on manhole covers and gully tops from the Mahape laboratory are issued outside the NABL scope, and the report says so. Concrete for precast covers can be tested separately on the accredited civil testing scope.

Which BS EN 124 load classes can TCR Engineering test?

All six: A15, B125, C250, D400, E600 and F900. The tests run on a servo-hydraulic dynamic UTM complying with EN ISO 7500-1, which applies at least 25 per cent more than the test load for classes A15 to D400 and at least 10 per cent more for classes E600 and F900.

What does the customer supply for a BS EN 124-5 fatigue test?

The customer supplies the fatigue test assembly: the cover or grating with its own frame, prepared as BS EN 124 Parts 1 and 5 require. The unit is tested complete, seated in its frame and supported as it will be installed, in compression to compression at room temperature, up to 100,000 cycles or until fracture.

Does TCR Engineering certify manhole covers?

No. TCR Engineering is a testing laboratory, not a certification body. It runs the BS EN 124 and Indian Standard tests a manufacturer needs for compliance validation or a Kitemark file, and reports each result against the load class the cover claims. Certification rests with the body the manufacturer appoints for it.

Test the fatigue life before the service load finds it.
