Decorative material veneer panels are increasingly used in home, office and commercial decoration. However, some manufacturers ignore product quality in pursuit of profits, resulting in quality risks in some artificial board products on the market. Therefore, it is particularly important to test decorative material veneer panels. The following is a detailed analysis of decorative material veneer panel testing:

Test items

The test of artificial boards for decorative materials is mainly divided into two categories: 

Physical performance test:

Thickness: measure whether the thickness of artificial boards meets the standard requirements.

Density: measure the mass of materials per unit volume and evaluate the density of materials.

Surface wear resistance: test the ability of the material surface to resist wear.

Surface scratch resistance: evaluate the ability of the material surface to resist scratches.

Impact resistance: test the ability of materials to resist external impact.

Water absorption rate: measure the ability of materials to absorb moisture, including 24-hour water absorption rate and water absorption thickness expansion rate.

Static bending strength and elastic modulus: test the bending resistance and elasticity of materials through three-point or four-point bending.

Internal bonding strength: test the bonding strength between the internal layers of the material.

Glue layer shear strength: evaluate the performance of adhesives under shear force.

Screw holding force: test the ability of materials to fix screws.

Moisture resistance: test the stability of materials in humid environments through boiling-drying method or cycle method.

Accelerated aging performance: simulate aging after long-term use.

Surface water vapor resistance: evaluate the durability of the material in a water vapor environment.

Light fastness, yellowing resistance, color stability: ensure the durability of the color.

Surface pollution resistance: test the material's ability to resist daily stains.

Chemical performance testing:

Formaldehyde emission: use the perforation method, dryer method, 1m³ climate chamber method, gas analysis method or small chamber method to measure formaldehyde emission to ensure that the product meets national standards or relevant regulations.

Heavy metal content: test whether the material contains excessive heavy metal elements.

Volatile organic compound (VOC) emission: pay attention to indoor air quality to ensure that the product does not release too many harmful substances during use.

Testing methods

Physical property testing: generally using electronic balance, vernier caliper, abrasion tester, hardness tester, water absorption tester, three-point or four-point bending tester and other equipment for testing.

Chemical property testing: requires the use of high-precision instruments such as gas chromatograph, atomic absorption spectrometer, spectrophotometer, etc. These equipment can accurately test and analyze samples to ensure the accuracy of test data.

Test report

The test report is a formal document of the test results, usually containing the following information:

Basic information: including the name, address, contact information of the testing agency, as well as the name, specifications, quantity, batch and other information of the test samples.

Test method: a detailed description of the methods, standards and instruments used in the test process.

Test results: list the test results of each test indicator, including numerical values, units, pass or fail information. For unqualified items, the specific reasons and degree of unqualified should be given.

Attachments: including auxiliary materials such as instrument calibration certificates used in the test process and test data record sheets.

In summary, the testing of decorative material veneer panels is of great significance in ensuring product quality, guiding consumption, and promoting environmental protection. When choosing a testing agency, you should pay attention to its qualifications, reputation, and service quality to ensure accurate and reliable test results.
