SAMPLE TEST / ST800-H
ST800-H specifications and test results.
The ST800-H uniform-load specification is 17,000 N/m². Report CIC-RJ-CC261105-01A tests 16,000 N/m² for its ST800-H 600 × 600 × 35 mm sample; the measured deflection is 0.95 mm. The specification and the report cover different load levels. The measured result applies to the tested sample.
| Test | Applied load / result | Measured response |
|---|---|---|
| Concentrated load | 3,560 N | Deflection: 1.34 / 1.40 / 0.83 mm; residual: 0.14 / 0.21 / 0.12 mm |
| Ultimate load | 12,724 / 11,209 / 12,888 N | Center / center of edge / quarter diagonal |

PROJECT SELECTION / QUESTIONS
Raised floor selection questions.
How are H and HN different?
Both belong to the HPL-finished steel floor family. H uses F-type PVC trim; HN is the no-trim technical option. Both use flat-head pedestals with stringers. Select the exact model and edge detail for the project.
Read the HN drawing ↗Why are two uniform-load values shown for ST800-H?
The ST800-H uniform-load specification is 17,000 N/m². Mechanical report CIC-RJ-CC261105-01A records a test at 16,000 N/m² with 0.95 mm deflection. The specification and test load are different. The measured result applies to the sample and conditions in the report.
Request Mechanical Report ↗Does selecting an HPL colour establish ESD performance?
No. Specify the required finish grade, resistance range and test conditions for the complete floor configuration. A colour reference is used to discuss a physical sample.
Electrical requirements and test information ↗PRODUCT DATA / PANELWAY
HPL facing data and maintenance.
Facing thickness options are 1.2 / 1.6 mm. The datasheet includes results for 1.2 mm laminate specimens, colour references and maintenance guidance. For panel construction and load performance, refer to the selected model specifications and its applicable test report.
