Batch sampling
Batch sampling is an important part of product quality control, which is used to evaluate the overall quality level of the product in the production batch. By randomly sampling samples from each batch of products for performance testing, safety testing and appearance inspection, batch sampling can find and eliminate nonconforming products in time to ensure that products meet design standards and customer requirements when leaving the factory. This method can ensure the efficiency of inspection and control the quality cost effectively.
Batch sampling
Batch sampling improves production efficiency and cost control while ensuring product quality. Through sampling testing, enterprises can quickly assess the overall quality of batch products, discover and solve potential problems in a timely manner, and ensure the reliability and consistency of outgoing products. Batch sampling provides a scientific basis for mass production quality management, while enhancing customers' trust in the product, helping enterprises to establish a long-term brand reputation.
Core content
Formulation of sampling plan
Content: According to international or industry standards (such as GB/T 2828), develop scientific sampling plans, including sampling quantity, frequency and inspection standards. Function: Ensure that the sample is representative and the test results can truly reflect the quality of the entire batch of products.
Electrical performance test
Content: Test key parameters such as capacity, internal resistance and voltage of the sampled products to verify whether the product performance meets the design requirements.
Role: To ensure that the battery provides stable and reliable performance in use.
Security detection
Content: Simulate the use scenario under extreme conditions, and test the sample battery for overcharge, overdischarge, short circuit, extrusion, etc., to evaluate its safety.
Function: Confirm the safety of the product in use and avoid potential risk accidents.
Visual inspection
Content: Check whether the battery shell is intact, whether the label is clear, whether the solder joint is firm and other appearance details.
Function: Eliminate potential quality problems caused by appearance defects and improve the market competitiveness of products.Function: To ensure the traceability of test data, to facilitate the later quality tracking and responsibility division.
Test result evaluation
Content: Statistical analysis of the results of sampling testing, and according to the predetermined standards to determine whether the batch of products qualified.
Function: Timely screening of unqualified batches to prevent problematic products from entering the market.
