Certificates, Test Reports & Technical References

Documented Evidence, International Test Reports, and Credibility Built Over Time

Belka is not presented through unsupported claims. It stands on a body of reports, evaluations, measurements, and technical references built across different countries, laboratories, and years.

This documentation base did not emerge as a one-time presentation package. It developed over time through fire testing, acoustic measurement, laboratory review, material analysis, and additional supporting technical references.

This page presents a curated selection of that accumulated documentation background.

Our Approach

Built on Testing, Not on Empty Claims

Belka’s documented background is not the result of a single documentation phase. It has grown through different laboratories, different technical contexts, and repeated evaluation over time.

That is what gives the documentation weight today: it was not assembled as a decorative archive, but developed as a serious technical and market-facing record of testing, review, and presentation.

For architects, distributors, project partners, and technical decision-makers, this signals continuity, seriousness, and substance behind the product.

Technical Background

A Multi-Layered Documentation Base

  • Fire Behaviour Documentation

  • Acoustic Measurement

  • Material and Laboratory Analysis

  • International Testing References

  • Broader Technical Context

Fire Testing

Documented Fire Behaviour Across Multiple Test Contexts

A central part of Belka’s evidence base concerns fire behaviour.

An early and important milestone comes from the United Kingdom. In the Bodycote warringtonfire testing environment, specimens were assessed to BS 476 Part 6 and BS 476 Part 7. The summary report records a Fire Propagation Index I = 5.1, Class 1 surface spread of flame, and an opinion that the product, as tested, complies with the requirements for a Class 0 surface.

The documented test build-up is equally important. The product was described as “Belka Interior Wall Coating”, tested as a single-coat coating system with 2 mm thickness, applied by hand by trowel on a 6 mm fibre cement board substrate.

These reports are not only technically valuable. They are also historically significant because they show that the product was already being assessed in a serious international fire-testing environment at an early stage.

  • Fire Propagation Index: I = 5.1
  • Surface spread of flame: Class 1
  • Summary opinion: Class 0, as tested

Acoustic Measurement

Measured Acoustic Performance Under Defined Conditions

Belka also has a clearly documented acoustic evidence base.

In the report issued by TÜV NORD Systems, the sound absorption of a BELKA wall coating was investigated in accordance with DIN EN ISO 354 and evaluated according to DIN EN ISO 11654.

The tested build-up used a BELKA wall coating prepared by adding water and applied at approximately 2 mm thickness onto a perforated gypsum board mounted on timber battens. The documented result is a weighted sound absorption coefficient αw = 0.4 (MH) and Absorption Class D.

This report is more than a sheet of numbers. It shows that the acoustic behaviour of the product was investigated and documented under controlled laboratory conditions.

Laboratory Review

Chemical Assessment and Laboratory-Based Review

Another important part of Belka’s documentation concerns laboratory-based material assessment.

In the SGS test report family for BELKA WALL COATING, soluble heavy metals including Lead (Pb), Cadmium (Cd), Chromium (Cr), and Mercury (Hg) were reported as ND. In the same report family, Benzene, Toluene, Ethylbenzene, and Xylene, including their total, were also reported as ND. Free Formaldehyde was reported at 35 mg/kg for the tested sample.

Belka’s broader laboratory background also includes supporting emissions-related references from Asia, reinforcing the impression that the brand’s documentation in the emissions and indoor-context field is not limited to a single country or a single document.

Supporting Fire-Related Laboratory Data

Belka also has supporting fire-related laboratory data documenting heat-release values for BELKA WALL COATING / Beige, adding another layer to the brand’s technical documentation background.

Material Analysis

Analytical Material Characterisation

Belka’s international documentation base also includes analytical material review.

In the Axxonlab / Airtests report, three BELKA samples were examined through analytical material investigation. The report documents no detectable asbestos fibres in the tested samples and identifies natural organic fibres as the dominant fibre component.

This is valuable because it shows that Belka is not described only through performance language, but also through analytical investigation that makes the product tangible from another technical perspective.

Material Identity

Beyond Reports: The Product as a Material System

Belka is not only documented through test data, but also understood through its applied material presence. Surface character, layer build-up, and real application appearance remain part of the product’s identity.

For this reason, the page should not rely only on logos and numbers. It should also show the material as it exists in practice — close-up, applied, and visually recognisable.

Broader Context

Broader Technical Background

Belka’s documentation base extends beyond a single technical theme. Alongside fire, acoustics, laboratory review, and material analysis, the broader documentation background also includes thermal and system-related references that contribute to the overall technical identity of the brand.

This section should be read as supporting technical context rather than as a simplified hard-sell performance claim.

International Reach

An Internationally Documented Product Background

What gives Belka’s documentation real identity value is not one isolated report, but the fact that the brand has accumulated technical references across different laboratories, countries, and years.

The current documentation base spans British fire testing, German acoustic measurement, Asian laboratory review, and Canadian material analysis. Together, these references show a product that has been reviewed repeatedly across different technical environments rather than introduced through a single local claim.

Behind the presentation stand real reports, real evaluations, and real documentation paths.
