BS EN ISO 8033 standard is for Rubber and plastics hoses - Determination of adhesion
between components (ISO 8033:2016).
This document specifies methods for the determination of the adhesion between lining and
reinforcement, between cover and reinforcement, between reinforcement layers, between cover and outer lamination (thin layer of material outside the cover for protection) and between lining and inner lamination (thin layer of material inside the lining to reduce permeation of fluid into the lining). Itcovers all bore sizes and the following types of hose construction:
— woven textile fabric;
— braided textile fabric;
— knitted textile fabric;
— circular-woven textile fabric;
— textile spiral;
— textile cord;
— wire braid;
— wire spiral;
— hoses containing a supporting helix.
Adequate adhesion between the various components of a hose is essential if it is to perform satisfactorily in service.
ISO 8033 standard Principle
Using test pieces of standard dimensions, the adhesion strength between lining and reinforcement, between cover and reinforcement, between reinforcement layers, between cover and outer lamination and between lining and inner lamination is measured under specified conditions.
