Method for LED quality inspection: 1. Type test. Verify that the product meets a technical specification (such as quality level, performance, safety requirements, environmental conditions, etc.) applicable to it. 2 routine tests (also known as factory tests). Inspect the quality defects of product materials and processing, and detect the inherent performance of the product, often including functional and safety testing items. 3 sampling tests. When there is a requirement in relevant product standards, the test is also used to verify the specified performance and characteristics of the product. These regulations can be proposed by the manufacturer or negotiated between the manufacturer and the user. 4 Special tests. It can be carried out according to relevant product standards and agreements between manufacturers and users to meet the diverse needs of the market for products. The climate environment includes: high temperature, low temperature, alternating high and low temperature, high temperature and high humidity, low temperature and low humidity, rapid temperature change, temperature shock, salt spray corrosion, gas corrosion, welding heat resistance, tin resistance, dust and waterproof (IP level), flame retardant testing, solar radiation, light aging, and so on; For testing and certification of lamps, please consult to ensure the accuracy of the test results. The electronic and electrical laboratories have introduced a large number of advanced testing equipment and are equipped with new software testing systems as needed. The standards based on which the inspection is conducted: the standards can be mandatory or recommended; It can be national standards, industry standards, local standards, enterprise standards, or product technical conditions. General supervision and spot checks are mostly based on national mandatory standards and some industry standards. The entrusted inspection can use the above standards or enterprise standards. For some newly developed products, the "product technical conditions" can be used for testing. For customized products for export, testing can also be carried out according to the technical requirements specified in the contract. Inspection items - The inspection items for supervision and random inspection are generally targeted at items that pose a threat to personal safety and health, as well as items with concentrated consumer complaints and significant quality issues. Entrusted inspection refers to enterprises selecting corresponding inspection items based on the characteristics of their own products and entrusting inspection institutions for inspection, which has certain pertinence and limitations. Inspection results - As a random inspection task issued by the national quality supervision department, clear inspection results are required: qualified or unqualified. If the inspection items are not complete during the entrusted inspection, it is generally not determined whether they are qualified or not. Only express the results of each individual inspection in the inspection report. The above are some information on the homepage of the inspection report, reflecting the comprehensive content of the inspection report. In the following pages of the inspection report, there are also detailed results of each individual inspection. In order to facilitate customers' reading of the inspection report, the inspection agency lists the relevant technical requirements and standard values of the inspection basis one by one, and also lists the corresponding measured results for users to refer to in detail. On the back page of the inspection report, there is also a description of subcontracting for some inspection items
