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 April 2026 and conflicting national standards shall be
withdrawn at the latest by April 2026.
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 13763-1:2004. Together with EN 13630-1:2025, EN 13631-1:2025 and
EN 13938-1:2025 this document will supersede EN 13857-3:2002.
a) the document title has been changed from “Detonators and relays — Part 1: Requirements” to

b) the Scope has been revised to clarify the covered explosives and to include semi-finished detonators,
electronic detonators and electronic initiation systems;
c) the normative references have been updated;
d) the Clause 4 “Requirements” has been completely revised so that now for each explosive a separate
subclause has been added divided into the following two sections each time:
1) a section on the requirements on information to be provided for the explosive – these
requirements have partly been moved here from EN 13857-3:2002 in revised form;
2) a section on the requirements on properties for the explosive – these requirements have partially
been taken over from the former Clause 4;
e) a differentiation between the different types of detonators has been introduced to Clause 4 – non-
electric, electric, electronic, plain and semi-finished detonators;
f) the requirements on electronic detonators, semi-finished detonators and electronic initiation
systems have been added;
g) the requirements on properties of the explosives covered in this document have been converted into
“pass”/ “fail”-criteria and the specification on these criteria are now given in the corresponding test
method standards of the EN 13763 series;
h) the former Annex A “Classification of electric detonators” has been removed;
i) a new Annex A “Specifications on reference detonators” has been added;
j) the former Annex B “Bruceton method” has been removed;
k) the Annex C is now called “PROBIT model” instead of “PROBIT TEST (PBBS test)”;
l) the former Annex D “Classification of defects” is now Annex B and has been updated to consider all
explosives covered in this document;
m) the former Annex E “Range of validity of test results” has been removed;
n) the Annex ZA has been updated;
