What are the regulations regarding sample collection and testing in the factory’s laboratory?

The sampling and testing procedures in a factory’s laboratory are generally as follows: 1. Sampling method: Appropriate sampling methods are used based on the properties of different substances, to ensure that the samples taken are representative and accurate. 2. Sampling environment: When taking samples, it is necessary to avoid interference from external factors such as impurities, temperature, and humidity. 3. Sample size: Depending on the items to be analyzed and the testing methods, the sample size should comply with the relevant standards and regulations. 4. Sampling process records: It is necessary to record information such as the time, location, quantity, and quality of each sampling session, for subsequent tracking and verification. 5. Analysis methods: Appropriate analysis methods and instrumentation are used for analysis and testing, depending on the properties and requirements of the various substances. 6. Qualifications of laboratory technicians: Laboratory technicians need to possess the relevant professional knowledge and skills, as well as necessary work experience and qualification certificates. In short, sampling and testing in a factory’s laboratory must be carried out in strict accordance with standards and regulations to ensure the accuracy, representativeness, and comprehensiveness of the samples. At the same time, laboratory personnel need to possess high-level technical skills and a strong sense of responsibility. You can’t just take some substance and put it at the laboratory window for analysis. .

For samples used in quality inspection, there should be sampling standards specific to different industries or the characteristics of the materials. Analytical testing is not some kind of game; taking samples casually is far too careless – it’s not the right attitude to have for this type of work.

Proper regulations should be established in the operating procedures. Generally, the QC department takes samples from raw materials and products. The intermediate production department will send the samples (it depends on the personnel assignment; QC can also go to pick them up). Sampling ensures the representativeness of the samples; the sampling tools must be clean to prevent contamination by previous batches of material or other impurities.
