LED Light Confirmation Test Report: Key to Sustaining CCC Certification & Market Access

In the highly competitive LED lighting market, an authoritative confirmation test report is not only a "health check" for product quality but also a "lifeline" to maintain certification validity and ensure market access.

After your LED lighting products successfully obtain the CCC certification certificate, the compliance journey does not end. According to the requirements of mandatory certifications worldwide, manufacturers must establish and implement a confirmation test procedure, and issue periodic confirmation test reports to prove that certified products continue to meet certification standards. As a professional institution with years of experience in testing and certification, GTG Testing Group deeply understands the importance of this continuous compliance work. This article systematically explains the core requirements, processes, and value of LED light confirmation test reports.

What Is an LED Light Confirmation Test Report?

A confirmation test report is an official document issued by manufacturers to fulfill post-certification supervision obligations. It involves periodically sampling certified LED lighting products from production lines or the market and retesting them in accordance with certification standards. Its core purpose is not R&D verification but to confirm that mass-produced products consistently and stably meet the safety, performance, and Electromagnetic Compatibility (EMC) standards required for initial certification.

It is fundamentally different from type test reports (for initial certification) and routine inspections (100% pre-delivery inspections):

In short, the confirmation test report serves as a critical bridge between "initial certification" and "sustained validity," and is essential documentation for responding to annual supervision audits by certification bodies.

Why Must LED Lights Undergo Periodic Confirmation Tests?

1. Mandatory Regulatory Requirements

Both China’s CCC certification (per factory quality assurance requirements) and major international market regulations explicitly mandate that certified factories establish and maintain documented confirmation test procedures, with records retained. Neglecting this requirement will directly lead to suspension or revocation of certification certificates.

2. Maintain Market Access Qualifications

Without valid confirmation test records, products are deemed non-compliant with continuous compliance requirements. Lack of this report may result in product delisting or order loss during market supervision inspections, e-commerce platform reviews, or customer factory audits.

3. Mitigate Production Consistency Risks

Changes in the supply chain (e.g., LED chips, drivers) or minor adjustments to production processes may inadvertently cause products to deviate from certification standards. Periodic confirmation tests are the most effective way to proactively identify and correct such deviations, preventing potential issues.

4. Enhance Brand Reputation & Customer Trust

Proactively conducting and presenting confirmation test reports demonstrates a sound quality management system and product responsibility, significantly boosting confidence among buyers and consumers.

Core Content & Process of Confirmation Tests

A complete confirmation test for LED lights typically selects key items for re-verification based on corresponding certification standards. Taking common CCC certification (GB standards) as an example:

Key Test Items

Safety Critical Items

• Durability of markings and instructions
• Structural checks (e.g., creepage distance, clearance)
• Protection against electric shock
• Insulation resistance and dielectric strength (withstand voltage test)
• Earthing provisions (if applicable)
• Temperature rise test
• Heat resistance, fire resistance, and tracking resistance

Performance & Energy Efficiency Critical Items (per applicable directives)

• Luminous flux, luminous efficacy
• Color rendering index, color tolerance
• Power factor

EMC Critical Items

• Conducted emissions, radiated emissions
• Harmonic current
• Electrostatic discharge (ESD) immunity

Standard Test Process

1. Planning & Sampling: The factory quality manager develops an annual plan based on procedural documents, randomly sampling a specified number of qualified products from the production line.
2. Submission & Testing: Send samples to a qualified third-party laboratory for testing in accordance with established certification standards.
3. Report Issuance & Review: The laboratory issues an official confirmation test report. The factory reviews the results and immediately initiates corrective and preventive actions if non-compliances are found.
4. Record Retention & Submission: Properly retain the report as a quality record (usually for at least one certification cycle) and proactively present it during annual audits by certification bodies.

Test Frequency

Typically at least once a year. Certification bodies or regulations may require increased frequency for products with unstable quality control.

Common Questions & Challenges

Q1: Can confirmation tests be conducted in-house?

A: Simple visual or functional checks may be performed in-house, but critical safety, performance, and EMC items requiring professional equipment (e.g., integrating spheres, EMC test chambers) must be completed by qualified independent laboratories to ensure objectivity and authority.

Q2: Is confirmation testing necessary if the product has no changes?

A: Yes, it is mandatory. The purpose of confirmation testing is to verify the validity of the "no changes" assumption. Even without design modifications, minor fluctuations in raw materials, processes, or personnel operations may affect product compliance.

Q3: What if the confirmation test fails?

A: Immediately suspend production and sales of the affected products, analyze the root cause (e.g., supplier changes, process errors), and implement thorough rectifications. Resample and retest after rectification—resume production and sales only after passing. Report the issue to the certification body as required.
