Specifies the values of normal modules for straight and helical gears for general engineering and for heavy engineering. Replaces the first edition.
Abstract
Overview
SIST ISO 54:1998 is an international standard developed by the International Organization for Standardization (ISO) that specifies the normal module values for cylindrical gears used in general engineering and heavy engineering applications. This standard provides definitions and standardized module sizes for both straight-toothed and helical cylindrical gears. As a technical revision, SIST :1998 replaces the first edition published in 1977, ensuring updated guidance aligned with modern engineering practices.
