What is EN ISO 38212019?

The EN ISO 3821:2019 is an international standard that sets the requirements for rubber hoses and hose assemblies used in a wide range of industrial applications. This technical article aims to provide a thorough understanding of the EN ISO 3821:2019, its significance, and the impact it has on various industries.

The Scope of EN ISO 3821:2019

The EN ISO 3821:2019 standard specifies the requirements for rubber hoses and hose assemblies used for welding, cutting, and related processes. It covers hoses operating with oxygen, acetylene, propane, and other fuel gases. The standard is applicable to both new hoses and hose assemblies as well as those already in service. Its purpose is to ensure the safe and efficient use of hoses in these critical applications.

Key Features and Requirements

EN ISO 3821:2019 defines several key features and requirements that hoses and hose assemblies must meet. These include specifications for burst pressure, flame resistance, flexibility, electrical conductivity, marking, and labeling. The standard sets out test methods and performance criteria to assess the conformance of hoses to these requirements. Compliance with these standards guarantees the reliability and safety of the hoses when used properly.

Impact on Various Industries

The EN ISO 3821:2019 standard has a significant impact on various industries that rely on rubber hoses and hose assemblies, particularly in welding and cutting operations. In these industries, the use of reliable hoses is essential to ensure worker safety and prevent accidents. Compliance with the standard not only avoids potential hazards but also enhances productivity by providing a consistent and high-quality product. Adhering to EN ISO 3821:2019 also promotes international harmonization, making it easier to trade and operate across borders.
