Obtaining a non-metallic component analysis report is indeed a crucial step in controlling material quality and compliance. This guide provides a complete overview of the non-metallic component analysis report application process.
I. Core Testing Scope and Items
Material Types: Plastics (PP/PE/PVC), Rubber, Glass, Ceramics, Textiles, Coatings, Adhesives, etc.
Required Test Items:
Qualitative Composition: Main Components (Resin/Polymer Type), Additives (Plasticizers/Antioxidants)
Elemental Analysis: Macroelements such as Carbon, Hydrogen, and Oxygen (Infrared Spectroscopy/Mass Spectrometry)
Hazardous Substances: Heavy Metals (Lead/Cadmium ≤ 0.1 mg/kg), Phthalate Esters (DEHP ≤ 0.1%), VOCs (Total Benzene Series < 500 mg/kg)
Physical Properties: Density, Melting Point, Hardness (Selected according to material application)
II. Processing Procedure (5 Steps)
1. Preliminary Preparation
Sample Requirements: 3-5 representative samples (≥ 50g/sample, sealed packaging, labeled with material name)
Technical Documents:
Product Instructions (including intended use, such as food contact/electronic insulation)
Known Composition Table (if available, can shorten the testing cycle)
Testing Standards (e.g., GB/T) 31818-2015, ISO 1043)
2. Key Points for Institution Selection
Qualification Requirements: Must possess CMA certification (China Metrology Accreditation) and CNAS laboratory accreditation.
Recommended Institution: Dezewei Testing CNAS Registration No.: L8083
Report Validity: Clearly defined purpose (CMA stamp required for e-commerce platform entry, English report required for export)
3. Testing Cycle and Cost
Cycle: Regular 5-7 working days (10 working days for complex components), expedited 3 days (cost +50%)
Cost: Approximately 2000-3000 RMB per material (varies depending on the number of items, e.g., adding heavy metal testing +800 RMB)
4. Key Testing Methods
| Testing Items | Instrument Type | Accuracy Range
| Principal Component Qualitative Analysis | FTIR Infrared Spectroscopy | Functional Group Identification Accuracy > 95%
| Heavy Metal Migration | ICP-MS Mass Spectrometer | Detection Limit 0.01 mg/kg
| Volatile Organic Compounds | Headspace Gas Chromatography (HS-GC) | Benzene Series ≤ 0.1 mg/kg
5. Report Review and Application
Core Elements: Must include detection standard number, instrument model, and sample spectral data (e.g., infrared absorption peaks)
Common Issues: If unknown components are detected, the laboratory can be requested to conduct a secondary search of the NIST spectral library.
Compliance Scenarios: E-commerce platform entry (CMA report required for Tmall/JD), export to the EU (must comply with REACH regulations)
III. Precautions
Sample Representativeness: Plastic granules must be mixed from different batches; coatings must be thoroughly stirred to avoid stratification.
Standard Updates: New restrictions on PFAS (perfluorinated compounds) were added in 2025; export products require extra attention.
Confidentiality Agreement: Sign a confidentiality agreement with the laboratory to prevent leakage of formulation information.
