What does the IEC60825 testing process and report test? How is IEC60825 determined to be compliant?

IEC60825 is the testing standard for laser products, an international standard test report, with CNAS accreditation.

The IEC60825-1:2014 version testing for laser modules is relatively simple, with the basic requirement being that the laser class meets the standards.

Samples required for IEC60825 testing of laser modules: 2 pieces per model with one driver power supply.

Keywords related to IEC60825-1:2014:

IEC/EN60825 primarily involves energy testing and calculation for single-wavelength light.

IEC/EN62471 mainly measures broad-spectrum light and calculates based on factors such as time, angle, and sensitivity of human eye and skin reactions to light.

Products applicable to IEC60825-1:2014:

All lamps and lamp systems except lasers. (Single-wavelength lasers are easy to test, whereas ordinary lamps may be broad-spectrum light sources due to the influence of emitters, diffusers, lenses, auxiliary optical components, etc.)

Wavelength range tested by IEC60825-1:2014:

Optical radiation with wavelengths ranging from 200nm to 3000nm.

Parameters and objects tested by IEC60825-1:2014:

Test parameters:

1. Irradiance (radiant flux divided by unit area, unit: W·m⁻²)

2. Radiance (irradiance divided by field of view, convertible from irradiance)

Test objects:

3. Ultraviolet hazards to skin and eyes

4. Near-ultraviolet hazards to the eyes (315nm-400nm)

5. Retinal blue light hazard

6. Retinal thermal hazard (for weak visual stimuli) (780nm-1400nm)

7. Infrared radiation hazard to the eyes (780nm-3000nm)

8. Skin thermal hazard (380nm-3000nm)

IEC 60825 is the testing standard for laser products, used to evaluate whether laser products meet international safety requirements. Test reports typically include the following main contents:
Test parameters and objects:
Irradiance (radiant flux divided by unit area, unit: W/m²)

Radiance (irradiance divided by field of view, convertible from irradiance)

Ultraviolet hazards to skin and eyes

Near-ultraviolet hazards to the eyes (315nm-400nm)

Retinal blue light hazard

Retinal thermal hazard (for weak visual stimuli) (780nm-1400nm)

Infrared radiation hazard to the eyes (780nm-3000nm)

Skin thermal hazard (380nm-3000nm)
Judgment of test results:
Continuous lamps: No hazard; Class 1 hazard (low risk); Class 2 hazard (medium risk); Class 3 hazard (high risk)

Pulsed lamps: Those exceeding radiation limits are classified as Class 3 hazard; single-pulse lamps not exceeding radiation limits are classified as no hazard; multi-pulse lamps not exceeding radiation limits are classified using the continuous lamp classification method, Level 1

Confirmation of laser product categories:
Determine the category of the laser product, such as Class 1, Class 2, Class 3A, Class 3B, Class 4, etc., based on the definitions in the IEC 60825 standard.
Other related tests:
Output power test: Measure the output power of the laser product to ensure it falls within the range specified by the standard.

Wavelength test: Measure the wavelength of the laser beam produced by the laser product to ensure it meets the relevant requirements of the standard.

Beam quality test: Observe and analyze the focusing and divergence of the laser beam using optical instruments.

Safety tests: Conduct tests on laser products under extreme conditions such as overload, short circuit, and overheating to evaluate the product's safety performance.

Reliability tests: Assess the long-term stability and reliability of laser products.

Label verification: Ensure that laser products are correctly labeled with information such as laser class and output power on their appearance and documentation.

How to determine compliance:

Conformity assessment: Test results must be compared with the requirements in the IEC 60825 standard to ensure all test parameters meet the standard limits.

Category determination: Based on test results, laser products are classified as Class 1, Class 2, Class 3A, Class 3B, or Class 4, with different categories corresponding to different safe usage conditions.

Hazard level: Assess the hazard level of the laser product based on its usage conditions and radiation characteristics, and determine corresponding safety measures.

The final test report will provide detailed testing methods, test results, and conclusions to enable manufacturers and regulatory agencies to accurately evaluate the product's safety. It is recommended that manufacturers strictly follow the IEC 60825 standard during the design and production of laser products to ensure product safety and compliance.

The IEC 60825 report testing process typically includes the following steps:
Confirm product requirements:
Determine whether the product requires IEC 60825 testing based on its characteristics and intended use.
Select a testing laboratory or certification body:
Choose an accredited laboratory or certification body with IEC 60825 testing qualifications, ensuring it has relevant certifications and experience in the IEC 60825 standard.
Negotiate the testing scope:
Discuss the specific testing scope with the selected testing laboratory or certification body, determining the test items required, including output power, wavelength, safety, and other aspects.
Submit test samples:
Provide a sufficient number of samples for testing. These samples should be representative of the production process to ensure test results reflect the actual product performance.
Test execution:
The testing laboratory or certification body executes the testing methods specified in the IEC 60825 standard, including measuring the output power and wavelength of the laser product, and conducting safety tests to ensure the product meets the relevant requirements of the standard.
Generate test report:
After testing is completed, the testing laboratory or certification body will generate an IEC 60825 test report, which should include detailed product information, testing methods, test results, and conclusions on compliance with the standard.
Report review:
The manufacturer or applicant reviews the test report to ensure the information is accurate.
Submit certification application:
If required, the manufacturer can submit the IEC 60825 test report along with other necessary documents to the regulatory agency to obtain IEC 60825 certification.
Wait for review:
Wait for the certification body to review the application. The review time may depend on the workload and review process of the certification body.
Obtain IEC 60825 certificate:
If the product passes the review, the manufacturer will receive an IEC 60825 certificate, which typically needs to be indicated on the product.
Ongoing compliance:
Once the IEC 60825 certificate is obtained, ensure the product continues to meet the requirements of the IEC 60825 standard. If the product changes, it may be necessary to resubmit the certification application.
Recommendations:
Before conducting IEC 60825 testing, it is recommended to collaborate with a professional testing laboratory or certification body to ensure the accuracy of testing and the reliability of the report.
Maintain good communication with the certification body and submit necessary documents and samples promptly to complete the certification process smoothly.
