Inorganic Surface Coatings – Sampling for Attribute Control. ISO 4519:1980 specifies methods for sampling inorganic surface coatings for attribute control, which involves inspecting and evaluating specific quality characteristics of the coating. The standard defines how samples should be taken from batches of coated items and which attributes should be assessed, such as thickness, adhesion, and appearance. The goal is to determine whether a batch meets technical specifications. Using a statistical sampling approach minimizes the number of samples required while ensuring the batch satisfies quality requirements. This standard is crucial for maintaining consistent production quality and reducing the risk of defective products.
