1. Visual and appearance test.

We visually inspect each piece to make sure they do not have protrusions or sharp edges and have correct shapes and aspects.

2. Torsion test.

At the beginning of production and 5 pieces in batches, we verify that the height should not vary from 5mm, from the crosshead end along its length.

3. Vertical load test.

At the beginning of production and 5 pieces in batches, we verify that the pate has the capacity to withstand an initial load of 2.0KN, during which its deflection will be equal to or less than 10.0 mm, after removing said load, its deflection will be equal Or less than 2.0mm. For final load of 4.0KN, deflection without load 10.0mm.

4. Unlocking resistance test.

At the beginning of production and 3 pieces per lot.

Method 1: Pates anchored at the factory. Block of 100x400x500mm. Concrete class c35 / 40 ISO 3893 with cement EN 197-1-CEM I 32.5N.

Method 2: Pates anchored during construction. Wall of 1x1x0.225m. Applying a force of 5KN before 60sec. And maintain it for 60sec.

5. Impact resistance test.

At the beginning of production and 5 pieces per lot.
20KG knocker, from 1m high without breaking, thanks to our 100% virgin material, the pate withstands the impact, while the covalent bonds remain seamless.

 

6. Integrity test of the plastic coating.

At the beginning of production and 5 pieces per lot.
Humid conditions.
We drilled the pate and immersed it halfway with 10mm of exposed metal in a solution of sodium chloride (3%) and a liquid agent (0.25%) for 30 min.
We connect one electrode to the exposed metal and another to the submerged metal. We do the same with the other half after drying out. Measurement greater than or equal to 1MW.

Dry conditions.
We drilled one end of the pate, connected one electrode to the exposed metal and another to the test brush, which is passed through the entire plastic surface. Measurement equal to or greater than 1MW.

7. Coating thickness test.

We cut the pate vertically in 5 points. The measurement is made on a gauge error plus / minus 0.05mm. The thickness of the plastic at any point must be greater than or equal to 2.5mm

Additional Tests

We have additional tests for the European standard EN-13101 and for the American standards ASTM C-478 and C-497 with dossier, LPRL 3111995.
Manhole Step model 400CR00A: The only pate on the market that complies with the law on prevention of occupational risks and royal decree 486/1997, which governs the minimum safety and health provisions in the workplace.

WE USE VIRGIN / NOT RECOVERED PLASTIC.

Pate Sugar is manufactured with non-recycled polypropylene copolymer and high-quality steel (B-500 standard) to ensure durability and long life of the step.

We do not use recovered materials on any of our models, ensuring the highest durability, strength and long life of the steps, with great performance despite the aggressive environments found in wells and their temperature changes.

The recovered materials used by other providers are not guaranteed to be a homogeneous and unique material. The various materials that make up the recovered plastic have different coefficients of expansion, therefore when the plastic cracks, it begins the oxidation process of the inner steel, causing the destruction of the steps.

SUPERIOR QUALITY – We not just say it. We prove it.

At Iverna 2000, we are proud of our products and our manhole steps are all about quality. We have our own lab for testing our steps, to make sure we meet and exceed all quality standards in accordance with the mandatory European Standard EN-13101.

We test our products every 1000 units produced and all our shipments are accompanied with a detailed report that is specific to that production batch and all required documentation in accordance with European norm EN-13101.
