Transportable gas cylinders - Gases and gas mixtures - Part 1: Properties of pure gases

This technical specification outlines the classification framework for gases and gas mixtures intended for use in portable gas cylinders. It defines key gas properties including physical characteristics, chemical behavior, and safety parameters essential for determining appropriate handling and storage protocols. The document serves as a foundational reference for categorizing various gaseous substances based on their distinctive traits, facilitating consistent identification across different applications and regions. By establishing clear criteria for distinguishing between different types of gases, it supports regulatory alignment and operational safety within the industry. The content focuses exclusively on the intrinsic properties of gases and their mixtures, providing a structured approach for classification without addressing implementation procedures or compliance obligations. This resource is designed to assist stakeholders in understanding the fundamental attributes that govern the classification of gaseous materials, ensuring clarity and uniformity in technical documentation and operational guidelines.
