What does ISO stand for in hydraulic fluid standards?

The correct answer refers to the International Organization for Standardization. This organization develops and publishes international standards across various industries, including hydraulic fluids. The standards set by ISO help ensure consistency, quality, and safety in products and services, providing a framework for the performance and compatibility of hydraulic fluids used in machinery and equipment globally. ISO standards are critical for manufacturers and users in understanding how hydraulic fluids should perform under specified conditions, contributing to better reliability and efficiency in hydraulic systems.

Understanding the relevance of ISO in hydraulic standards underlines its role in promoting safe and standardized practices, which is essential in the hydraulic industry. The other options do not accurately define ISO, as they either refer to organizations with different focuses or misrepresent its purpose.
