Acceptance testing for National Science and Technology Major Projects is a mandatory verification process that confirms whether project deliverables—such as advanced equipment, key materials, core chips, and software systems—meet the defined technical objectives, contract requirements, and applicable national and international standards. Performed by accredited third-party laboratories, this testing supplies the objective technical evidence required for formal project closure and acceptance by national science and technology administration authorities. This guide explains the testing scope, sample categories, test items, methods, applications, and frequently asked questions related to acceptance testing for National Science and Technology Major Projects.
Technical Overview
National Science and Technology Major Projects are large-scale, state-funded research and development programs established under a national medium- and long-term science and technology development framework. These programs span strategic fields including core electronic devices, high-end chips, basic software, integrated circuit manufacturing, new-generation broadband mobile communications, high-end CNC machine tools, nuclear energy, oil and gas exploration, water pollution control, biopharmaceuticals, high-resolution earth observation, and large aircraft development.
Acceptance testing, also referred to as acceptance inspection or verification testing, is the technical evaluation stage of the formal project acceptance process. Its purpose is to independently and objectively verify that the deliverables produced during project implementation conform to the approved task objectives, technical specifications, and relevant standards. Testing results serve as core supporting evidence for both technical acceptance and financial acceptance reviews conducted by the responsible administrative bodies.
Because project conclusions carry significant administrative and financial consequences, acceptance testing must be performed by qualified laboratories with recognized accreditation, such as CNAS laboratory accreditation or CMA testing qualification, and the testing organization must be independent of the project undertaking units. Testing generally follows a documented workflow covering project review, test planning, sample registration, test execution, data review, and issuance of a formal test report.
- Verify conformity of deliverables to approved technical indicators and contract requirements
- Provide objective, traceable, and reproducible test data for acceptance review panels
- Confirm compliance with applicable national standards, industry standards, and international standards
- Identify technical risks and deviations before formal project closure

Testing Methods
All testing is carried out in accordance with published national, international, or industry standards. Where multiple standards apply, the acceptance test plan defines the priority order agreed among the project office, the undertaking unit, and the testing laboratory.
Environmental Test Methods
Environmental testing generally follows the GB/T 2423 series and the IEC 60068 series for climatic and mechanical environmental testing, supplemented by the GB/T 5170 series for verification of test equipment. Products intended for demanding field use may additionally be assessed using IEC 60068-2 specific procedures for combined or sequential stress testing.
EMC Test Methods
Emission and immunity testing follows the GB/T 17626 series and the IEC 61000-4 series for immunity, and the GB/T 9254, GB 4824, and CISPR-based IEC standards for emissions, with the applicable limit class determined by the intended installation environment.
Safety Assessment Methods
Information technology and audio-video equipment is evaluated against GB 4943 and IEC 62368-1 hazard-based safety requirements. Flammability of polymeric materials may be assessed using the UL 94 horizontal and vertical burning tests, and machinery products against relevant EN safety standards for mechanical and electrical hazards.
Material and Chemical Analysis Methods
Mechanical property testing follows GB/T 228.1 and ASTM E8/E8M for tension, GB/T 230 and ASTM E18 for hardness, and ASTM E384 or the equivalent JIS hardness method for micro-indentation. Microstructure is examined by optical and electron microscopy, composition is quantified by ICP-based spectrometry and combustion analysis, and corrosion resistance is assessed by salt spray exposure per ASTM B117 and cyclic corrosion test protocols.

FAQ
Who is qualified to perform acceptance testing for these projects?
Testing must be carried out by accredited third-party laboratories holding valid laboratory accreditation (such as CNAS accreditation or CMA qualification) with testing capabilities covering the relevant standards and technical domains. The laboratory must be organizationally independent from the project undertaking and participating units.
Is third-party testing mandatory for project acceptance?
Yes. For most major projects, deliverables that require objective performance evidence must be tested by a qualified independent laboratory, and the resulting test report is a mandatory attachment to the acceptance application file reviewed by the acceptance panel.
What documents are required before testing can begin?
Typical documents include the project task statement or contract, technical specifications, design documents, a test requirement list defining indicators and acceptance limits, the user manual, and any prior self-test records. The laboratory reviews these documents to prepare a formal acceptance test plan and test case specifications.
How long does acceptance testing take?
The duration depends on sample complexity and the number of test items. Simple component-level verification may be completed within a few weeks, while comprehensive system-level programs involving environmental, EMC, reliability, and software evaluation may require several months, particularly when accelerated life testing is included.
What happens if a deliverable fails a test item?
Failures are documented in the test report with measured data, test conditions, and deviation analysis. The undertaking unit typically performs root-cause analysis and corrective action, after which retesting of the affected items is arranged. Acceptance can proceed only after all indicators are demonstrated to conform to the specified requirements.
