What is ISO 3821:2019? .

Introduction

ISO 3821:2019 is an international standard that establishes the requirements for rubber hoses for welding, cutting, and allied processes. It provides guidelines for the design, construction, and performance of these hoses to ensure safety and efficiency in various industrial applications.

Main Features of ISO 3821:2019

The standard defines specific characteristics and parameters that rubber hoses need to meet in order to comply with ISO 3821:2019. These features include:

Resistance to fuel gas and oxygen: ISO 3821:2019 sets the minimum requirements for the hoses' resistance to fuel gas and oxygen, ensuring their suitability for welding and cutting operations.

Flexibility: The standard specifies the flexibility requirements of the hoses, allowing them to be easily maneuvered in different working conditions without compromising their performance.

Durability: ISO 3821:2019 establishes durability tests that evaluate the hoses' resistance to abrasion, aging, and degradation caused by exposure to extreme temperatures and chemicals.

Marking and identification: The standard provides guidelines on how to mark and identify the hoses, including important information such as the manufacturing date, type, and maximum working pressure.

Benefits and Applications

Adhering to ISO 3821:2019 offers several benefits, both for manufacturers and end-users. These advantages include:

Enhanced safety: The standard ensures that the rubber hoses used in welding, cutting, and allied processes meet strict safety requirements, reducing the risk of accidents, leaks, and failures.

Improved performance: ISO 3821:2019 sets performance criteria that enhance the hoses' reliability, durability, and efficiency, resulting in improved overall performance during industrial operations.

Compatibility: Compliant hoses guarantee compatibility with welding and cutting equipment, allowing for smooth and reliable connection and usage.

ISO 3821:2019 finds applications in various industries, including metal fabrication, construction, automotive, and shipbuilding. It ensures the use of reliable hoses, contributing to efficient and safe welding, cutting, and allied processes.
