Obtaining a non-metallic material composition analysis test report typically requires entrusting a third-party testing organization with CMA (China Metrology Accreditation) or CNAS (China National Accreditation Service for Conformity Assessment) qualifications.
1. Core Process
It generally consists of the following five steps:
Consultation and Quotation: Contact the testing organization, specify the material type (e.g., plastics, rubber, ceramics, coatings, etc.) and the purpose of the test (e.g., quality control, R&D formula analysis, export compliance, etc.), and obtain a quotation.
Sample Submission: Prepare samples according to the organization's requirements (usually a few grams to tens of grams), fill out the testing request form, and send it to the laboratory.
Note: If formula confidentiality is involved, a confidentiality agreement (NDA) can be signed in advance.
Laboratory Testing: After receiving the samples, the organization develops a testing plan and uses professional instruments (e.g., FTIR, GC-MS, XRF, etc.) for qualitative and quantitative analysis.
Data Review and Report Preparation: Engineers review the data and prepare a formal test report.
Report Delivery: An electronic or paper version of the report is issued (usually supporting both Chinese and English), and technical interpretation can be included. 2. Common Testing Items and Methods
For non-metallic materials, common analytical items include:
Elemental Analysis: Detection of C, H, O, N, S, Cl, and metallic impurities.
Common Methods: X-ray fluorescence spectrometry (XRF), inductively coupled plasma mass spectrometry (ICP-MS).
Main Component Identification: Determining the type of base resin in polymer materials (e.g., PE, PP, PVC, ABS, etc.).
Common Methods: Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR).
Additive/Auxiliary Agent Analysis: Detection of the type and content of plasticizers, flame retardants, antioxidants, fillers, etc.
Common Methods: Gas chromatography-mass spectrometry (GC-MS), thermogravimetric analysis (TGA).
Hazardous Substance Screening: Detection of lead, cadmium, mercury, hexavalent chromium, etc., as required by RoHS, REACH, and other regulations.
3. Reference Standards
Testing organizations typically conduct tests based on the following standards (specific standards vary depending on requirements):
National Standards (GB): Such as GB/T 223.3, GB/T 6040, GB 5009.268, etc.
International Standards: ISO 11885, ASTM E1421, ASTM D6581, etc.
Industry Standards: Specific standards for particular industries (such as automotive, electronics, building materials).
4. Processing Time and Costs
Time: Routine testing usually takes 5-7 working days, expedited processing is available.
Cost: Depends on the complexity of the test item.
Single qualitative analysis: Starting from several hundred yuan.
5. Recommended Types of Organizations
It is recommended to choose a reputable organization to ensure the legal validity and market acceptance of the report:
Well-known third-party organizations: Such as Dezewei Testing (CNAS registration number: L8083).
