DIN EN ISO 30013:2012

Rubber and plastics hoses - Methods of exposure to laboratory light sources - Determination of changes in colour, appearance and other physical properties (ISO 30013:2011); German version EN ISO 30013:2011

This International Standard specifies methods for the exposure of rubber and plastics hoses to three types of laboratory light source (xenon-arc, fluorescent UV and open-flame carbon-arc lamps). These methods are designed to simulate the exposure of hoses used in an outdoor environment (exposure to xenon-arc lamps by method A, exposure to fluorescent UV lamps by method A and exposure to open-flame carbon-arc lamps with type 1 filters) or in an indoor environment (exposure to xenon-arc lamps by method B, exposure to fluorescent UV lamps by method B and exposure to open-flame carbon-arc lamps with type 2 filters). Four types of test piece (two strained and two unstrained upon exposure) are specified. Results from the three light sources and the different sets of exposure conditions specified are not comparable.*This test standard specifies methods for the exposure of rubber and plastics hoses to three types of laboratory light sources (xenon-arc, fluorescent UV and open-flame carbon-arc lamps). This way changes in colour, appearance and other physical properties caused by the weather can be assessed. Results from the three light sources and the different sets of exposure conditions specified are not comparable. This document has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products", SC 1 "Hoses" of the International Organization for Standardization (ISO) and has been adopted by Technical Committee CEN/TC 218 "Rubber and plastics hoses and hose assemblies". The committee responsible for this standard is NA 045-02-12 AA "Schläuche" ("Hoses") at the Rubber Technology Standards Committee (FAKAU).
