What is EN ISO 8031:2017?

EN ISO 8031 is a technical standard published by the International Organization for Standardization (ISO) that provides guidelines and specifications for flexible rubber and plastic hoses used in various industries. The standard covers a wide range of hoses, including those used for suction, delivery, and discharge purposes, as well as hoses used for fuel, oil, air, and water systems. EN ISO 8031 was first published in 1997 and has since undergone revisions to ensure its relevance and compliance with industry requirements.

Scope and Application

The scope of EN ISO 8031 includes both straight and curved hoses, as well as hose assemblies made from rubber or plastic materials. It provides recommendations for the design, construction, testing, and performance of these hoses to ensure their durability, reliability, and safety under various operational conditions. The standard applies to hoses used in a wide range of industries, including automotive, industrial, marine, and construction sectors.

Key Requirements and Testing Methods

EN ISO 8031 specifies several key requirements that hose manufacturers need to comply with, such as dimensional tolerances, burst pressure limits, flexibility, and resistance to chemicals and aging. These requirements are essential to ensure that the hoses perform effectively in their intended applications. The standard also outlines specific testing methods to assess the quality and performance of the hoses, including tests for burst pressure, tensile strength, vacuum resistance, and flexibility.

Benefits and Importance

Complying with EN ISO 8031 offers numerous benefits to both manufacturers and end-users. For manufacturers, adhering to the standard helps streamline their production processes, ensure product consistency, and meet market demands. It also enhances the reputation and credibility of the manufacturer, as it demonstrates their commitment to high-quality products. For end-users, using hoses that comply with EN ISO 8031 provides assurance of reliable and safe performance, minimizing the risk of accidents or failures that could result in downtime or damage.

In conclusion, EN ISO 8031 is a vital standard for flexible rubber and plastic hoses used in various industries. By providing guidelines and specifications, it ensures that these hoses are designed, manufactured, and tested to meet stringent quality and performance requirements. Compliance with this standard not only benefits manufacturers but also ensures the safety and reliability of the hoses for end-users.
