Quality control

We bear full responsibility for the quality of our products and constantly improve them.

Tests performed

Research and innovation

We pay great attention to the scientific side of production processes. All KASTAMONU plants have dedicated teams of experts in research and development, quality control and operational properties of our products.

We constantly research and modify our products, trying to improve their consumer characteristics, increase environmental friendliness and improve production processes. Depending on the results obtained in our laboratories, new developments are tested under production conditions.

Tests and comprehensive research allow us improving our products in a variety of ways. In particular, as a result of such experiments, we were able to modify the equipment and make changes to the technological process of paper impregnation with resins, which allowed us to significantly improve the quality of laminated boards and floorings.

We do not stop on our achievements and continue to search for new opportunities to improve our products.

quality

The KASTAMONU research and development laboratory is fully equipped with modern testing and measuring equipment. An experimental site for field (production) tests was built separately.

We constantly check the quality of our products for compliance with the standards of Turkey, Russia, and the EU countries.

Kastamonu Enterprises are certified under quality standards ISO9001, ISO14001, OHSAS18001.

KASTAMONU means high-quality products

The laboratory staff has checked the quality of products through numerous tests and trials to confirm the reliability and declared properties of products, which allows us meeting expectations of customers, including without causing harm to their health and the environment.

  • Determining laminate T-joint swelling

    Procedure:

    • measure thickness at several points on samples;
    • assemble elements in the T-joint;
    • tightly clamp assembled elements in the test unit;
    • ensure tightness of the fitting ring by applying a sealant;
    • pour 1 liter of cold distilled water for 24 hours;
    • upon the expiration of the designated time, repeat thickness measurements at the already planned points;
    • take the average edge swelling index expressed in % as a result;
    • standards for laminate without bevel: max ≤ 1%, for laminate with bevel: max ≤ 4%.

    The test determines the preservation of laminate properties upon an accidental spillage of liquid.

  • Scratch resistance

    Standard: min. 3.5 N.

    Procedure:

    • the sample is placed in a device with an Erichsen 413 diamond scratching needle;
    • the test begins with a load of 1 Newton, and continues with an incremental step of 0.5 N: 1N, 1.5 N, 2N, 2.5 N, etc.;
    • use a contrast agent to visualize and display scratches;
    • by visual inspection, determine the load having led to the formation of a continuous scratch on an area of at least 90%;
    • test result is recorded in Newtons;

    Guarantee of glossy panel surface resistance to minor impact by a sharp object in everyday life.

  • Micro scratch resistance

    Glossy panels / Evogloss, Acrylic

    Method: EN 16094.

    Procedure:

    • install a limiting plate on the sample and perform preliminary measurements of the surface gloss degree within it;
    • the sample is exposed to an abrasive material in the test unit. Rotation speed of 80;
    • repeat measurements of the surface gloss degree;
    • the loss of gloss must not exceed 60% after exposure to the abrasive material;

    Guarantee of Evogloss and Acrylic glossy panel surface resistance to the exposure to light abrasive material in everyday life.

  • Resistance to shock load by a small diameter ball

    Laminate / Floorpan, Sunfloor

    Method: EN 438-2, EN 13329+А1.

    Standard: 32 class – 12N, 33 class – 15N, 34 class – 20N.

    Procedure:

    • the laminate sample is hit with a 5 mm steel ball using Erichen impact test gun;
    • evaluate results for surface damage using a magnifying glass;
    • there is no visible damage to the laminate surface;

    The test determines the class of floorings: 32, 33 or 34.

  • Determining formaldehyde migration by the gas analysis method

    Laminate /

    Method: EN 717-2, EN 12460-3.

    Standard: Е1 less than 3.5 mg/m² ∙hour.

    Procedure:

    • place the sample in the Grecone GA6000 gas analyzer chamber;
    • expose to a temperature of 60° C and a pressure of about 1100 Pa for 4 hours;
    • quantitative determination of formaldehyde is carried out by the chemical analysis;

    Constant monitoring of formaldehyde migration guarantees environmental friendliness and safety of products for consumers.

  • Mirror effect

    Glossy boards / Evogloss, Acrylic

    Method: the test is carried out under the standards of the Kastamonu group of companies.

    Standards: min. 6 lines.

    Procedure:

    • place the sample of 210*300 mm (A4) at a height of 50 cm;
    • read the lines of "Inverted alphabet" in the reflection of the plate surface at a distance of 1 meter from the sample;
    • letters of each row are read one after the other;
    • take the number of fully readable lines as a result;
    • the degree of gloss is determined by the Byk micro-TRI - gloss meter, with a 20-degree angle;

    Determining the degree of gloss and regular reflectance is a significant competitive advantage of Evogloss boards.
