Certificates and test reports

Two commissioned inspection reports cover the partition assembly and the aluminium profiles behind it, both issued by an independent Chinese testing body. Report numbers, standards, requirements and measured results are published below.

Where the reports come from

Scanned copies and sealed originals are available on request. Send us the report number and the project it is for, and we will provide the PDF, including the latest issued version.

Report 1 — the partition assembly
