All WINTECH products undergo rigorous in-house as well as third-party quality testing. All of them are tested in our laboratory for impact resistance, colour, gloss, dimensions, weld-ability and other critical factors.

Additionally, every quarter, our products are tested and revalidated by independent third-party testing agencies, ensuring quality, reliability and performance standards.

Raw Material Testing

All raw materials, imported or indigenous, are regularly tested before they enter the production process. While each raw material undergoes specific additional quality tests, generic tests include:

  • Colour – ISO: 7724-3
  • Bulk Density
  • Moisture
  • Sieve Analysis

In-Process Testing

During extrusion, our products are continuously monitored to ensure the profiles in production meet the basic visual requirements such as:

  • Appearance – ISO: 105-A01
  • Dimensions – ISO: 12608-2003
  • Distortions – ISO: 12608-2003
  • Colour & Gloss – ISO: 7724-3

Performance & Physical Tests

We ensure that post-production samples from every batch are tested on a range of parameters before the products are accepted into the warehouse. Qualified technicians conduct these tests in a state-of-the-art laboratory at the factory as per RAL: GZ-716/1 and EN: 12608 standards.

In addition to the in-house tests conducted, post-production samples are also sent to independent testing agencies for periodic quality validation through the following tests:

  • Appearance Tests:
    • Surface Flatness – ISO: 12608-2003
    • Mass per unit length – ISO: 12608-2003
    • Bending – ISO: 12608-2003
  • Heat Performance Tests:
    • Heat Revision – DIN EN: 479
    • Heat Deformation – DIN EN: 478
    • Vicat Softening Temperature – DIN EN: 306
    • Flammability Test* – UL-94
    • Cold Impact @-10C – EN: 477
  • Mechanical Tests:
    • Charpy Impact Test – ISO: 179-1/1
    • Corner Weld Strength – DIN EN: 514
    • Tensile Strength* – ISO: 527
    • Flexural Modulation* – ISO: 178
  • Ageing Test:
    • Xenon Arch Test* – DIN EN: 513

Window Performance Tests

We also undertake window performance tests in addition to profiles testing. These tests ensure that windows manufactured using WINTECH profiles meet the necessary local requirements.

  • Casement Windows
    • Air Infiltration Test* – BS EN 12207:2000
    • Static Water Penetration Test* – BS EN 12208:2000
    • Resistance to Wind Load* – BS EN 12210:2000
  • Sliding Windows
    • Air Infiltration Test* – BS EN 12207:2000
    • Static Water Penetration Test* – BS EN 12208:2000
    • Resistance to Wind Load* – BS EN 12210:2000

Please Note* – These tests are solely conducted by external independent certified agencies.
