(Main)Explosives for civil uses - Propellants and rocket propellants - Part 2: Determination of resistance to electrostatic discharge
Explosives for civil uses - Propellants and rocket propellants - Part 2: Determination of resistance to electrostatic discharge
This document specifies a method for the determination of resistance to electrostatic energy for propellants containing a mass fraction of at least 5 % of particles which pass through a 1 mm sieve. This method does not apply to black powder.
NOTE If the mass fraction of particles smaller than 1 mm size is less than 5 % the propellant is considered to be insensitive to electrostatic energy and this test is not performed.
Explosivstoffe für zivile Zwecke - Treibladungspulver und Raketentreibstoffe - Teil 2: Bestimmung der Widerstandsfähigkeit gegen elektrostatische Energie
Dieses Dokument legt ein Verfahren für die Bestimmung der Widerstandsfähigkeit gegen elektrostatische Energie für Treibladungspulver, die mindestens 5 % Massenanteil an Partikeln enthalten, die durch ein Sieb mit einer Maschenweite von 1 mm hindurchpassen, fest. Dieses Verfahren gilt nicht für Schwarzpulver.
ANMERKUNG Ist der Massenanteil an Partikeln, die kleiner als 1 mm sind, unter 5 %, dann wird davon ausgegangen, dass das Treibladungspulver unempfindlich gegenüber elektrostatischer Energie ist und diese Prüfung wird nicht durchgeführt.
Explosifs à usage civil - Poudres propulsives et propergols pour fusées - Partie 2 : Détermination de la résistance à l'énergie électrostatique
Le présent document spécifie une méthode de détermination de la résistance à l'énergie électrostatique des poudres propulsives contenant une fraction de masse d'au moins 5 % de particules passant à travers un tamis de 1 mm. La présente méthode ne s'applique pas à la poudre noire.
NOTE Si la fraction de masse des particules de taille inférieure à 1 mm est inférieure à 5 %, la poudre propulsive est considérée insensible à l'énergie électrostatique, et cet essai n'est pas réalisé.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 321.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.
