Establishing the exact reference points, lines, or planes from which measurements are taken. JIS B 0024 vs. ISO 8015 and ISO 1101
JIS B 0024の最も重要な概念が （Independence Principle）です。これは、 「サイズ公差」と「幾何公差」は、特別な指示がない限り、それぞれ別々に指示されたものとして扱う という考え方です。

Evolution is central to the standard’s longevity. The original 1988 version was closely aligned with ISO 8015:1985. However, the current JIS B 0024:2019 Establishing the exact reference points, lines, or planes
is a standard you cannot ignore. It defines the fundamental concepts and rules for Geometrical Product Specifications (GPS) that ensure parts fit and function as intended. What is JIS B 0024? Revised in 2019 to align with international
If you are searching for a reference, it is essential to understand not just where to find the document, but how to interpret its core concepts, how it aligns with international standards, and why it is indispensable for modern quality control. What is JIS B 0024? It defines the fundamental concepts and rules for
Treating dimensional tolerances and geometric tolerances as separate entities unless specified otherwise.
