1、 The core steps of the inspection process

Inspection application and preparation

Clear purpose: to determine the type of inspection (such as incoming inspection, process inspection, final inspection) and the standards based on (national standards, industry norms, or contract requirements).

Contact institution: Select a qualified testing institution to confirm the detectable items, cycle, and cost.

Sample preparation: Randomly select representative samples according to standards (such as GB/T 21862-2008), and perform pre-treatment such as crushing and dissolution to ensure that the sample state meets the requirements.

Inspection implementation

Preliminary inspection: Quickly determine through appearance, pH value measurement, etc.

Accurate measurement: Quantitative analysis is performed using instruments such as gas chromatography and moisture analyzer to detect key indicators such as purity, moisture, and impurities.

Quality control: Conduct parallel experiments, use standard substances, participate in proficiency testing to ensure accurate and reliable data.

Report issuance and result processing

Report preparation: The testing agency issues a detailed report, including sample information, methods, results, and conclusions.

Result review: Reviewed by technical personnel and reviewed by the responsible person to ensure the authenticity and effectiveness of the report.

Follow up processing: If there are objections to the report, a re inspection can be applied for; Qualified products are released, while unqualified batches are reworked or destroyed according to regulations.
