REGULATIONS AND QUALITY STANDARDS FOR RUBBER, SILICONE, AND TEFLON HOSES IN THE INDUSTRY

It can be said that food flexible hoses are the most special product line in the industrial hoses segment. This type of hose requires the most stringent standards and requirements because the flexible hoses must be in direct contact with the products being transported. At the same time, flexible hoses will help the product prevent contamination from the outside environment. Therefore, hose production materials must ensure durability, safety for users’ health and be resistant to corrosion.

For the above reason, safety standards and certifications for food – pharmaceutical – chemical hoses are always very strict. Many manufacturers and buyers always focus on whether the hose meets the necessary hygiene and safety standards (e.g. 3A standards, FDA standards, etc.) or not?

To learn more about standards for flexible hoses, let’s read the article below with Khanh Anh!

Applicable to all types of flexible hoses

ISO 1307:2006 – Flexible Hoses – Minimum Bending Radius

Specifies the acceptable minimum bending radius for flexible hoses, ensuring that the material maintains its structural integrity during use.

Applicable to Rubber Hoses

ISO 3821:2019 – Flexible Hoses for Welding and Cutting Gases

Establishes requirements for flexible hoses used in the transport of welding and cutting gases, defining criteria for material strength, flexibility, and safety.

EN ISO 8031:2020 – Flexible Rubber and Plastic Hoses – Determination of Electrical Resistance and Conductivity

Specifies electrical testing methods for flexible rubber and plastic hoses to determine electrical resistance, conductivity, and electrical continuity between metal end fittings.

UNI EN ISO 1762 – Rubber Hoses and Hose Assemblies for Liquefied Petroleum Gas (LPG), Propane, and Natural Gas

Specifies requirements for rubber flexible hoses used for the transfer of liquefied petroleum gas (LPG) and natural gas with a maximum working pressure of 25 bar.

UNI EN ISO 1765 – Rubber Hoses for Loading and Unloading Petroleum Products

UNI EN ISO 1825 – Rubber Hoses and Hose Assemblies for Aircraft Ground Fuelling and Defuelling Services – Specifications

Applicable to Silicone Hoses

USP Class VI – Biocompatibility

Defines the biocompatibility of silicone materials, with applied testing methodologies to ensure suitability for pharmaceutical applications.

ISO 10993 – Biocompatibility Evaluation

International standard providing guidelines for the biocompatibility assessment of medical devices, including silicone hoses, ensuring safety in clinical use.

Applicable to Teflon Hoses

FDA 21 CFR 177.1550 – Regulation for Materials in Contact with Food

FDA regulation in the United States for Teflon hoses intended for the food industry, establishing safety criteria for materials in contact with food.

Conclusions

Compliance with regulations and quality standards is crucial to ensure the reliability and safety of Rubber, Silicone, and Teflon hoses in the industry. The knowledge and application of these standards are crucial for manufacturers to meet the specific requirements of various industrial applications and ensure regulatory compliance.
