Geometrical product specifications (GPS) - Callipers - Maximum permissible errors

The DIN 862:2015 standard, published by the German Institute for Standardization (DIN), specifies the maximum permissible errors for calipers used in geometric product specification (GPS). This standard is essential for ensuring the accuracy and reliability of calipers, which are widely used in manufacturing, quality control, and metrology.

The standard defines the tolerances for various types of calipers, including vernier calipers, dial calipers, and digital calipers. It covers the measurement range from 0 to 2000 mm and provides detailed guidelines on the maximum allowable errors for both internal and external measurements. These errors are categorized based on the measurement range and the resolution of the caliper, ensuring that the instruments meet the required precision for different applications.

DIN 862:2015 also includes specifications for the design and construction of calipers, ensuring that they are durable and capable of maintaining their accuracy over time. The standard emphasizes the importance of proper calibration and maintenance to minimize measurement uncertainties and ensure consistent performance.

By adhering to DIN 862:2015, manufacturers and users of calipers can ensure that their measurements are accurate and reliable, which is crucial for maintaining quality and precision in various industrial processes. This standard is widely recognized and adopted in the field of metrology, contributing to the global harmonization of measurement practices.
