Commissioned test record, not a general certificate
Commissioned testing record for the submitted sample only. The report states that its results are limited to the submitted sample and does not provide an overall conformity determination.
The record shows the submitted sample as a 12 mm Concrete Canvas / cement blanket. It lists no overall judgement criterion. The issuer's report says the submitted information and sample were provided by the entrusting company, and the test results are limited to that submitted sample and that testing occasion.

Technical interpretation boundary
What the report cannot establish on its own
The record does not establish results for all thicknesses, batches, material constructions or future production. It does not identify a 3D textile, a 3D spacer construction, a composite woven construction or a needle-punched construction. It should not be used to claim universal standards compliance, permanent waterproofing, a production-line capacity or a named field-project outcome.
For equipment discussions, use this record as one item in a larger evidence set that also includes the exact textile construction, raw-material and process plan, controlled sample preparation and the project-specific methods and acceptance criteria.
