European foreword
This document (EN 1762:2017) has been prepared by Technical Committee CEN/TC 218 “Rubber and
plastic hoses and hose assemblies”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2017, and conflicting national standards
shall be withdrawn at the latest by September 2017.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1762:2003.
Compared to EN 1762:2003 the following changes have been made:
a) Clause 2: The normative references have been updated;
b) Table 3 has been technically amended (property no. 5); in accordance with corrigendum
EN 1762:2003/AC of November 2007.
c) Clause 8.4 has been divided into 8.4.1 and 8.4.2 to clarify the requirements for the 2 different
grades of M and Ω hoses
d) Clause 9: The text has been amended editorially;
e) Clause 10: The text has been amended editorially;
f) Clause 11.1: The text has been amended editorially.
Annex A and B are normative. Annex C is informative.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 8330 and the following
apply.
3.1
electrically bonded hose/hose assembly
hose/hose assembly that uses a metallic wire connection to conduct static electricity
3.2
electrically conductive hose/hose assembly
hose/hose assembly that is capable of conducting static electrical charges, using a conductive rubber
layer, without the use of a metallic wire
3.3
electrically discontinuous hose/hose assembly
hose /hose assembly that incorporates a metallic wire connection to one end coupling of the assembly
only or is electrically insulated from both end-couplings
4 Classification
Hoses/hose assemblies for this application are classified into 5 types and 3 grades according to their
use, construction, and electrical properties. The maximum WP for all hoses/hose assemblies is 25 bar.
Type Application
D delivery hose
D-LT delivery hose, low temperature;
SD suction and delivery hose, helix reinforced
SD-LTS suction and delivery hose “smooth hose”, helix reinforced, low temperature
SD-LTR suction and delivery hose, rough bore (having an internal, non-embedded helical
wire of stainless steel), low temperature
Hoses for this application are divided into 3 grades according to their electrical properties:
Grade Electrical property
designation
M Electrically bonded
Ω Electrically conductive using a conductive rubber layer
Discontinuous Electrically discontinuous
