particular purposeinspection of goodshit the nail on the headDrop TestIt is a reliability test that simulates accidental drop impacts that may occur during transportation, handling or use of a product. It is mainly used to evaluate the protective performance of the packaging of the product as well as the impact resistance of the product itself.
I. Purpose of Drop Test
1. Assessment of packaging protection: Verify that the packaging (outer box, inner liner, cushioning material) is effective in absorbing impact energy and preventing damage to the product inside.
2. Evaluation of product ruggedness: Tests the ability of key components of the product itself (e.g., screen, structural elements, connections, functional components) to withstand impacts from dropping.
3. Identify design flaws: Expose weaknesses in product design or packaging design.
4. Reduce the risk of transportation damage: Identify problems in advance, improve packaging or product design, reduce the rate of damage and return during actual transportation and handling, and save costs.
5. Satisfy customer requirements/standards: Perform test programs as specified by the customer or relevant industry standards.
Second, drop test method
1. Determine the test program: according to the weight, size, nature of the product (fragile, precision, etc.) and customer requirements or relevant international standards (the most common is the ISTA series of standards, such as ISTA 1A, 2A, 3A, etc., or ASTM D5276, D4169, etc.) to formulate a specific drop test program.
2. Selection of drop height: This is the key parameter. The height is usually based on the weight of the product (the higher the weight, the lower the expected handling height) and standard requirements. Common heights range from a few tens of centimeters to over a meter.
3. Determine the number and direction of drops: The standard will specify the number of drops required (e.g., 1, 5, 10, etc.) as well as the corners, edges, and surfaces to be dropped (usually each corner, edge, and surface will need to be dropped at least once).
4. Preparation of samples: Use packaging and products exactly as shipped.
5. Perform Drop: The packaged product is dropped freely from a drop tester (or manually in a prescribed manner) onto a hard horizontal impact surface (usually concrete or steel plate) at a predetermined height, direction and number of times.
6. Inspection and evaluation:
Packaging Inspection: Check whether the outer box is cracked or deformed, and whether the inner lining is shifted or broken.
Product Inspection: Check the appearance of the product for scratches, dents, cracks, and deformation. Perform a function test to confirm that all functions are working properly (power on, buttons, display, connection, performance, etc.). Check the internal structure (disassemble if necessary) for loose, broken parts.
7. Records and reports: Detailed records of the test process (height, direction, number of times), packaging and product condition after dropping (text description, photos, video), and functional test results. Third Partyinspection companyA formal inspection report containing this information will be issued with a "pass" or "fail" conclusion.
III. Role in third-party inspection
1. Objectivity and impartiality: The results are more credible as they are carried out by a third party independent of the buyer and seller.
2. Professionalism and standardization: The third-party inspection company has professional technicians and operates in strict compliance with international or customer-specified standards.
3. Risk Management: Helps customers identify potential transportation damage risks prior to shipping large quantities of product.
4. Quality verification: Verify that the products and packaging provided by the supplier meet the quality requirements and durability standards agreed upon in the contract.
5. Provide a basis for improvement: A report of a test failure provides a clear basis for the supplier to improve the package design or product structure.
IV. Importance of Drop Test
1. Especially important for fragile products, electronic products, precision instruments, home appliances, toys and other products.
2. PreventionNegative impact on customer perception of the productThe
3. It can effectively reduce wastage and post-sale costs in the supply chain.
To summarize, the drop test in the third-party inspection, is an independent professional organization, in accordance with the pre-set strict standards (height, direction, number of times), simulating the reality of possible drop scenarios, impact testing of products with packaging, and then a comprehensive inspection to assess whether the packaging and products are damaged or functionally ineffective, and ultimately to provide an objective inspection and test report.
