Explosives for civil uses - Detonators and detonating cord relays - Part 2: Verification of thermal stability of detonators, surface connectors, detonating cord relays and shock tubes

This document specifies a test method for the verification of thermal stability.
This document is applicable to electric detonators, non-electric detonators, electronic detonators, plain detonators, semi-finished detonators, surface connectors and detonating cord relays as well as shock tubes.
This document does not apply to electronic initiation systems.

Explosivstoffe für zivile Zwecke - Zünder und Sprengschnurverzögerer - Teil 2: Überprüfung der thermischen Stabilität bei hohen Temperaturen

Dieses Dokument legt ein Verfahren für die Überprüfung der thermischen Stabilität von elektrischen Zündern, nichtelektrischen Zündern, Sprengkapseln, elektronischen Zündern, Oberflächenverbindern, Sprengschnurverzögerern und Zündschläuchen zur Verwendung mit elektronischen und nichtelektronischen Zündern fest.
Dieses Dokument ist anzuwenden für Explosivstoffe für zivile Zwecke.
Explosivstoffe werden bei niedrigen Temperaturen stabiler und daher berücksichtigt dieses Verfahren keine Temperaturen unter (75 ± 2) °C.

h) the Clause 8 “Expression of results” has been added;
i) the Clause “Test report” does no longer require conformity with EN ISO/IEC 17025 and the
information to be provided has been revised and enlarged;
j) the Annex ZA has been updated;
k) the Bibliography has been added and lists EN ISO/IEC 17025:2017.
