Tolerance limits

Tolerance limits are predefined boundaries used in quality control and manufacturing to specify the acceptable range of variation for a product's characteristics, such as size or strength. They ensure that products meet desired standards while allowing for minor variations that naturally occur during production. If a measurement falls within these limits, the product is considered acceptable; if it falls outside, it may need adjustment or rejection. Tolerance limits help maintain consistent quality, balance production efficiency, and ensure customer satisfaction by clearly defining acceptable performance ranges.
