Full title and description

STB DIN EN ISO 8331 E 2011-09 — Rubber and plastics hoses and hose assemblies: Guidelines for selection, storage, use and maintenance. (German title: Gummi- und Kunststoffschläuche und -schlauchleitungen - Richtlinien für die Auswahl, Lagerung, Verwendung und Wartung).

Abstract

This document provides practical, non‑mandatory recommendations intended to preserve rubber and plastic hoses and hose assemblies prior to and during use so they remain as close as possible to their as‑received condition and achieve the expected service life. It covers selection criteria, storage and handling practices, inspection and routine maintenance measures and general safety considerations.

General information

• Publication date: September 2011 (document date reported as 2011-09-19 in national catalogues).
• Publisher: Adopted as a national variant of EN/ISO by DIN (CEN/CENELEC adoption of ISO text; original ISO work by ISO/TC 45/SC 1).
• ICS / categories: 23.040.70 — Hoses and hose assemblies.
• Edition / version: 2011 (designation shown as DIN EN ISO 8331:2011 / prEN ISO 8331:2011 in national listings).
• Number of pages: ~18–21 pages (varies by national publication/format).

Scope

This standard gives non‑prescriptive guidance for the selection, storage, use and maintenance of rubber and plastics hoses and hose assemblies. It is intended to be used alongside applicable statutory regulations and product‑specific standards (pressure‑rated hoses, fuel hoses, hydraulic hoses, etc.) and addresses measures to avoid premature degradation, contamination, mechanical damage and unsafe conditions during storage, handling and service.

Key topics and requirements

• Guidance on appropriate selection of hose materials and constructions for intended fluids, temperatures and mechanical loads.
• Recommended storage conditions (temperature, humidity, protection from sunlight/ozone, stacking and support methods).
• Handling and installation practices to avoid kinking, twisting, abrasion and incorrect fittings.
• Inspection intervals, visible‑condition checks and simple non‑destructive tests to detect aging or damage.
• Maintenance and cleaning recommendations to limit contamination and chemical attack.
• Labeling, traceability and documentation best practices to preserve service history and ensure correct replacement.

These topics are presented as guidelines rather than mandatory test criteria; users should apply them in combination with product‑specific standards and regulations.

Typical use and users

Widely used by hose manufacturers, quality and maintenance engineers, procurement specialists, plant operators, safety officers and technicians responsible for storage and servicing of hose assemblies in industries such as hydraulics, chemical processing, petroleum, agriculture, construction and general manufacturing. The guidance is intended to support those establishing in‑house procedures for handling and maintaining hose stocks and installed assemblies.

Related standards

FAQ

Q: What is this standard?

A: DIN EN ISO 8331 (2011) is a guideline document giving recommendations for selection, storage, use and maintenance of rubber and plastics hoses and hose assemblies to preserve their condition and expected service life.

Q: What does it cover?

A: It covers non‑mandatory recommendations on material selection considerations, storage conditions, safe handling and installation, inspection and maintenance practices, and documentation/traceability for hose assemblies. It does not replace product‑specific performance or safety regulations.

Q: Who typically uses it?

A: Manufacturers, maintenance and reliability teams, procurement and safety personnel across sectors that use flexible hoses and assemblies (hydraulics, fuel systems, chemicals, agriculture, construction, etc.) to establish practical handling and maintenance procedures.

Q: Is it current or superseded?

A: The 2011 national/committee adoption listing has been withdrawn and later replaced by subsequent editions (references show replacement activity in 2014 and later consolidated ISO/EN editions up to 2016). Users should refer to the latest ISO/EN publication for the current active text.
