A halogen test report typically refers to a report testing the halogen (fluorine, chlorine, bromine, iodine) content in a product. It's particularly important in industries like electronics, plastics, and wires and cables, often used to meet relevant environmental regulations (such as halogen-free requirements) and customer requirements.
The processing procedure is generally as follows:
1. Clarify Testing Needs
Standards: Confirm the specific testing standards you need to follow, for example:
International Electrotechnical Commission (IEC) Standard: IEC 61249-2-21 (Printed Circuit Board Materials).
EU Regulations: Such as restrictions on PBB and PBDE (brominated flame retardants) in the RoHS Directive, but halogen testing is often an extension of these requirements.
Industry/Customer Requirements: Common "halogen-free" requirements typically refer to:
Chlorine (Cl) < 900 ppm
Bromine (Br) < 900 ppm
Chlorine + Bromine (Cl + Br) < 1500 ppm
Products and Materials: Determine the specific product components and material types that need testing (e.g., plastics, coatings, substrates, flux, etc.).
1. Report Purpose: Is it for internal quality control, supply chain management, or as a required document for export, bidding, or customer certification?
2. Choosing an Authoritative Testing Organization
Find a third-party testing laboratory with qualifications such as CNAS (China National Accreditation Service for Conformity Assessment) and CMA (China Metrology Accreditation), and whose relevant testing items are within their accreditation scope.
Reputable international organizations include Dezeway Testing (CNAS registration number: L8083).
When selecting, compare their qualification scope, testing cycle, fees, and services.
3. Submitting an Application and Samples
Contact the Organization: Communicate with the testing organization's sales staff, explaining your specific products, testing standards, and expected requirements.
Complete the Application Form: Submit a testing application, clearly stating company information, product description, testing standards, specific items (such as total chlorine, total bromine, specific halogen compounds, etc.), and report requirements.
Send Samples: Prepare and send a sufficient number of representative samples according to the organization's requirements. The organization may inform you of the required sample quantity.
4. Payment and Testing
Pay the testing fees according to the organization's quotation. After receiving the samples and payment, the laboratory will arrange for testing according to standard methods (such as ion chromatography, combustion ion chromatography, X-ray fluorescence spectrometry, etc.).
5. Obtaining the Test Report
After testing, the laboratory will issue a formal test report.
Report Content: Typically includes information about the testing organization, applicant information, sample description, testing standards, testing methods, test results, conclusions (e.g., whether the "halogen-free" requirement is met), report issuance date, and signature/stamp.
You will receive an electronic or paper version of the report. Please carefully check that the information in the report is accurate.
Important Notes:
Advance Communication: Before submitting the sample for testing, be sure to confirm all details with the testing organization, including the validity of the standard version, sample requirements, testing cycle (usually a few days to about a week), and fees, to avoid subsequent problems.
Sample Representativeness: The representativeness of the sample directly affects the validity of the report. If it is a homogeneous material, sampling is relatively simple; if it is a finished product, the testing location must be clearly identified.
Report Validity: Generally, the test report is for the batch of samples submitted and does not have a fixed "validity period." However, if there are changes in product design, materials, or suppliers, retesting is usually required.
In summary, the key steps to obtaining a halogen test report are: clarifying the standard requirements → selecting a qualified laboratory → submitting samples and entrusting testing → obtaining and verifying the report.
