SGS Test Report — Physical & Chemical Performance
Every number a designer writes into a material specification needs a citable test report behind it. Hengsheng commissions SGS as an independent global laboratory for physical and chemical testing: compressive strength, water absorption, abrasion resistance and slip resistance, together with radionuclide limits and heavy metal content, referenced to ASTM, EN and GB standards.
Core Strengths
- Complete physical profile: compressive strength, water absorption, abrasion resistance and slip resistance are the routine suite, matched to the different loads and uses of floors, walls and countertops.
- Chemical safety control: radionuclide limits and heavy metal content are tested to confirm compliance with Class A decorative material requirements and safe interior use.
- Multi-standard referencing: testing covers the full ASTM, EN and GB families, satisfying documentation requirements on American, European and Chinese standard projects alike.
- Batch-level traceability: reports are tied to batch codes, traceable back from finished code to quarry and block batch, and citable at acceptance or in dispute.
Key Figures
Service Process
- Sampling: specimens drawn by batch code from the same block or slab, with quarry and batch recorded.
- Specimen preparation: machined to the dimensions required by the test standard.
- Testing: physical properties and chemical safety indicators measured separately.
- Reporting: SGS issues the test report stating standard basis and test conditions.
- Archiving: reports bound to batch codes for retrieval at dispatch and acceptance.
Applications
- Projects whose specification demands performance data
- Cross-border orders meeting destination import testing requirements
- Performance verification at acceptance of public buildings
- Third-party documents used as evidence when quality is disputed
Sustainability & Certification
Radionuclide and heavy metal testing underpins indoor environmental safety and, together with GREENGUARD Gold low-emission certification, forms a complete evidence set for interior materials.
Independent data on inbound and finished material reduces scrap and rework from non-conforming stock, indirectly cutting energy and waste, with fabrication waste utilisation above 85%.
Deep Selection Guide
When reading a test report, check three things: that the batch code matches the goods, which standard family was used, and whether test conditions match the real environment — dry or wet slip testing, for example. Write the required test items and standard family into the contract and require reports with the delivery; match report to physical code on receipt. Where a project spans markets, ask for comparative ASTM, EN and GB data so later re-testing for standard differences does not delay the programme.
- Selection criteria:For Projects whose specification demands performance data, fix the stone type and finish by position and traffic intensity first, then align colour and veining direction; Complete physical profile is the criterion that follows.
- Specification & thickness:Take Routine physical tests (4) as the baseline for thickness and size, then adjust to the actual conditions of Cross-border orders meeting destination import testing requirements; where junctions, cut-outs or corners are involved, mark them on the fabrication drawing in advance to avoid cutting on site.
- Acceptance & records:Complete checks on Chemical safety control before dispatch and keep the record; accept on site by numbering, so any dispute can be traced back to that batch and its test data.
- Sustainability:Radionuclide and heavy metal testing underpins indoor environmental safety and, together with GREENGUARD Gold low-emission certification, forms a complete evidence set for interior materials. Build this into the acceptance documents and align it with the green building requirements where the project sits.
On SGS Test Report — Physical & Chemical Performance, Hengsheng manages the full chain from quarry-direct sourcing, smart manufacturing, global delivery and on-site installation. The advantage lies not in a single product but in connecting selection, fabrication, QC and delivery into an auditable loop, giving project teams clear assurance on programme, quality and compliance.
FAQ
- How does a test report differ from certification?
- Certification such as ISO or CE is continuing recognition of a system or product compliance; a test report is the measured result for a specific batch sample. They complement each other: certification demonstrates capability, the report states what this shipment actually measured.
- Can we specify which standard is used?
- Yes. Testing covers the full ASTM, EN and GB families and can be specified by project location or design code; where a project spans several markets, comparative data can be provided to avoid repeated re-testing later.
