ISO 9001 Certificate J25Q2SH8026349R1S
ISO 9001:2015 / GB/T 19001-2016. Valid through 06 Nov 2028.
Scope boundary
Accreditation applies only to activities within the current formal CNAS scope. Method-specific applicability is confirmed during project scoping.
Project controls
Make the analytical path visible from input to delivery.
Defined scope
Align the product context, analytical question, sample inputs, comparison plan, and expected output before work begins.
Traceable handoffs
Maintain clear sample, data, and review handoffs across the agreed analytical workflow.
Scientific review
Review findings against the agreed question, comparison context, and interpretation boundaries before delivery.
Delivery path
Four checkpoints keep expectations and conclusions aligned.
- 01
Scope confirmation
Confirm inputs, questions, comparison context, and reporting expectations.
- 02
Sample and method review
Check sample constraints, references, handling needs, and analytical fit.
- 03
Technical review
Review data quality, observations, limitations, and interpretation context.
- 04
Clear delivery
Deliver the agreed outputs with transparent conclusions and boundaries.
Records & confidentiality
Keep project evidence and approval boundaries visible.
- Documented sample and data handoffs within the agreed project path
- Method context and deviations recorded where applicable
- Technical review and report approval before delivery
- Data integrity and confidentiality expectations defined during project scoping
