DIN 68861 Furniture Surface Resistance Testing for Tables and Desks
The DIN 68861 standard is a crucial reference for testing the surface resistance of furniture, including tables and desks. This test ensures that furniture surfaces are safe from electrical leakage, which can lead to accidents or damage. The primary purpose of this test is to evaluate the performance of the insulating layer on furniture surfaces by measuring the resistance between two points.
This standard applies to a wide range of wooden and upholstered furniture pieces commonly found in offices, schools, and homes. Testing ensures that these surfaces meet safety requirements set forth by international standards, such as DIN 68861-2015. Compliance with this standard is essential for manufacturers aiming to produce safe and durable furniture products.
The testing process involves placing electrodes on the surface of the furniture item being tested. A specific voltage is then applied between these electrodes, and the surface resistance is measured. The test provides a quantitative measure of the insulating properties of the material used in the furniture's construction. This information helps manufacturers understand the effectiveness of their materials and allows them to make necessary adjustments.
For quality managers and compliance officers, understanding this standard ensures that products meet safety regulations. R&D engineers can use these insights to innovate safer designs, while procurement teams ensure suppliers comply with the standards specified.
The test setup for DIN 68861 is straightforward but requires careful preparation of the specimen. The furniture surface must be clean and dry before testing begins. The electrodes are placed at a predetermined distance from each other, ensuring they do not touch or interfere with the integrity of the test.
Understanding the implications of this standard for different types of furniture is essential. For instance, wooden tables may have a more porous surface compared to solid wood ones, affecting their insulation properties. Upholstered items also present unique challenges due to the variety in materials used.
Scope and Methodology
| Test Parameter | Description |
|---|---|
| Electrode Placement | Electrodes are placed at 50 mm (2 inches) apart on the surface. |
| Voltage Applied | A voltage of 10 V is applied between the electrodes. |
| Measurement Point | The resistance measured between the two points after applying the voltage. |
The process begins with selecting a representative sample of the furniture to be tested. The surface should be clean and dry, free from any contaminants that could affect the test results. Electrodes are then carefully placed on the specified area according to the standard's requirements. A voltage is applied between these electrodes, and the resistance measured after a short duration.
The methodology outlined in DIN 68861 ensures consistent testing across different manufacturers and products. This consistency helps establish reliable data that can be used for quality assurance purposes. The results of this test provide valuable information to stakeholders involved in ensuring product safety and compliance with standards.
