Open guideReport boundary
A COA describes what was tested for a stated material.
Its usefulness depends on whether the product, lot, method, result and acceptance limit are readable and tied to the material being purchased. The site does not claim universal certification or independent testing capability.
- Exact product and lot identity.
- Test method, result and specification limit.
- Representative versus lot-linked status.
- Independent testing scope when one is agreed.
Keep the specification, method, result, lot and commercial record connected.
Common questions
What buyers usually ask first
Does a high purity number prove product quality?
No single headline proves quality. Read the test method, report scope, identity checks, specification and lot traceability together.
Is ACTIVITY a testing laboratory?
The site is an analytical-document review route. Do not infer an in-house testing accreditation or service unless the exact provider and scope are confirmed in writing.
Can ACTIVITY review a third-party report?
The report structure and questions can be reviewed. The buyer should independently verify the laboratory, sample chain and scope where required.
