: Finer; used for precision mechanical parts like small gears or wheels. Key Features of ISO 20457
The TG5 designation refers to a specific test group within the ISO 20457 standard, which focuses on the testing of medical devices for skin irritation and sensitization. This test group provides a framework for manufacturers to assess the biocompatibility of their devices and ensure they do not cause adverse skin reactions. Iso 20457 Tg5

When reviewing a design specifying TG5, ensure the following callout is present on the technical drawing to avoid disputes: Core Function and Classification
serves as the "standard" or baseline precision grade for plastic injection molded parts. It is the most commonly applied tolerance series for industrial and consumer plastic products where high precision is desired without the extreme manufacturing costs of high-precision grades like TG1-TG3.
