This standard specifies a test method for evaluating the impact resistance of surface coatings on wooden furniture components, aiming to simulate damage to the finish caused by hard object impacts during daily use. The core principle of the test involves using a steel impact block of specified weight, which is allowed to fall freely from a specific height through a vertical guide tube, striking a standard steel ball placed on the surface of the test specimen. The impact resistance grade is then assessed by observing the extent of damage, such as cracks or peeling, at the impacted area of the coating. The key equipment for performing this test is a specialized coating impact resistance tester (also known as a wood impact tester). This type of instrument is typically equipped with a vertical guide tube marked with a scale (e.g., 400 mm), an impact block of precise weight (e.g., 500 g), and a high-hardness steel ball with a diameter of 14 mm. Some models also include a controller to accurately set and lock the release height, ensuring standardized test conditions and comparable results. This method is applicable to components of finished furniture or dedicated test samples, providing an important basis for quality control and process improvement in furniture production.
