Liquefied petroleum gases - Method of sampling

This technical specification establishes the fundamental procedures for obtaining representative samples of liquefied petroleum gas from various sources and storage conditions. It outlines the necessary equipment requirements, ensuring that sampling tools are constructed from materials compatible with the product to prevent contamination or chemical reactions during collection. The document details the specific steps for sampling from pressurized vessels, pipelines, and rail or road tank cars, emphasizing safety protocols to manage high-pressure environments. It addresses the importance of maintaining sample integrity from the point of extraction until analysis. The methodology covers both gas and liquid phase sampling techniques, providing guidance on valve operations and sample container preparation. By adhering to these principles, industry professionals can ensure accurate testing results that reflect the true composition of the gas supply. The approach promotes consistency across different facilities and operational contexts, supporting quality control measures throughout the supply chain. This framework aligns with broader international practices for hydrocarbon sampling, facilitating mutual recognition of test data in trade and regulatory compliance.
