WHY ZHONGJIAN

Why Zhongjian Testing

Zhongjian Testing provides a complete service process covering test selection, methods, quality control, data review and report delivery.

Verified Credentials

Accreditation, test items and methods are checked against the intended report use and the latest valid scope.

Requirement-led

We begin with the sample, standard, application and practical question, then define the technical objective and route.

Fit-for-purpose Methods

Methods are selected around sample condition, target parameters and decision criteria to prevent scope mismatch.

Controlled Process

Key stages from sample receipt and preparation to testing and data review are recorded and quality controlled.

Integrated Expertise

Inspection, testing, instrumental analysis and failure diagnosis are coordinated for complex technical requirements.

Traceable Outcomes

Report information, test data, technical review and authorisation form a closed, traceable chain with clear limitations.

COMMISSION PROCESS

Testing Commission Process

From project registration and quotation to testing, analysis and report delivery, every step is clear, controlled and traceable.

PROJECT WORKFLOW

From Registration
to Final Report

Submit the sample and testing request, then proceed through quotation, sample receipt, testing, review, authorisation and report delivery.
