Inspection Standards: Corresponding by Category
The quality inspection standards for prefabricated building components, corresponding to categories, are: rebar connections (JGJ 107 category), fasteners (performance grade), embedded parts (welds/materials), and seismic bracing (load-bearing capacity testing). Industry insiders point out that the “What are the quality inspection standards for prefabricated building components?”
are corresponding to categories—rebar connections (process inspection), fasteners (grade testing), embedded parts (weld material), and bracing (load-bearing capacity). The inspection standards (corresponding to categories) are implemented according to national standards/industry specifications, and the reports are verified.
By Category
- Reinforcing bar connection: Connection process inspection (sleeve grouting/straight thread), structural critical;
- Fasteners: Performance grade (8.8/10.9), inspection;
- Embedded parts: Weld/material inspection (Q235/stainless steel), verification;
- Seismic bracing: Load-bearing capacity inspection (support load), safety;
- Component certification: Prefabricated components (certification standards), system.
Key points of implementation
First, category correspondence.
Inspection standards (category correspondence) are implemented to prevent mislabeling.
Second, report verification.
Third-party reports (institutional qualifications) are verified to prevent fraud.
Third, batch sampling inspection.
Each batch is sampled (batch report), ensuring stable quality.
Fourth, on-site verification.
On-site process inspection (connection sampling inspection) is conducted for verification.
Pitfall Avoidance Tips
First, “Report Forgery”.
Forged test reports (fake reports) require third-party verification.
Second, “Incorrect Standard Application”.
Incorrect standard application (misattribution), mismatched product categories.
Third, “Inspection Only, No Batch Sampling”.
Only samples are inspected, not batches (batch omissions), batch sampling is necessary.
Trends and Reminders
Assembled testing is moving towards “digitalization”: The trend towards test report traceability (digitalization) and non-destructive testing (intelligent testing).
For purchasers, we recommend “product category matching, report verification, and batch sampling.”
Strict adherence to testing standards ensures quality.
