Pyrotechnic articles - Other pyrotechnic articles - Fixing cartridges
EN 16264 defines the procedures for classifying, testing and labelling of cartridges for powder actuated tools (PAT cartridges), as defined in Clause 3 of this standard. This European Standard does not apply to pyrotechnic articles containing blasting agents and military explosives except black powder and flash composition. PAT cartridges contain pyrotechnic composition(s) delivering mainly gases, intended to propel a piston. The piston propels fasteners (e.g. nails) or drives hard marking characters into appropriate materials. This standard also applies to PAT cartridges sold to persons younger than 18 years, if this is permitted by the member state due to the low hazard of the PAT cartridges.
Pyrotechnische Gegenstände - Sonstige pyrotechnsiche Gegenstände - Befestigungskartuschen
Die vorliegende Europäische Norm legt Anforderungen an und Prüfverfahren für Befestigungskartuschen fest.
Befestigungskartuschen sind Kartuschen, die Stoffe enthalten, die im Wesentlichen Gase abgeben, die dazu bestimmt sind, für Befestigungszwecke Befestigungsmittel (z. B. Nägel) in feste Werkstoffe zu treiben.
Diese Norm gilt auch für Produkte, die an Personen unter 18 Jahren verkauft werden, wenn dies durch das Mitgliedsland aufgrund der geringen Gefährlichkeit des Produkts gestattet ist.
In Tabelle 1 sind die eingeführten Kaliber für Befestigungskartuschen aufgeführt.

La présente Norme européenne définit les modes opératoires liés à la classification, à l'essai et à l'étiquetage des charges de scellement pour outils utilisant ces mêmes charges tels que définis à l'Article 3 de la présente norme.
La présente Norme européenne ne s'applique pas aux articles pyrotechniques contenant des explosifs, et explosifs militaires, autres que de la poudre noire ou une composition éclair.
Les charges de scellement PAT contiennent une ou plusieurs compositions pyrotechniques libérant principalement des gaz, dans le but de propulser un piston. Le piston, à son tour, propulse des projectiles (par exemple, des clous) ou entraîne des caractères de marquage dur dans des matériaux appropriés.
La présente norme s'applique également aux charges de scellement vendues aux particuliers de moins de 18 ans, si cela est permis par l'État membre, en raison du faible risque induit par les charges de scellement.
NOTE Les charges de scellement peuvent également être utilisées pour les outils de marquage. Les informations concernant les outils de marquage et de scellement figurent dans l'EN 15895.
La présente Norme européenne s'applique aux charges de scellement listées au Tableau 1.
Pirotehnični izdelki - Drugi pirotehnični izdelki - Pritrdilne kartuše
Standard EN 16264 definira postopke za klasifikacijo, preskušanje in označevanje kartuš za plinska orodja (kartuše PAT), kot je definirano v točki 3 tega standarda. Ta evropski standard se ne uporablja za pirotehnične izdelke, ki vsebujejo vojaški eksploziv in tržne eksplozivne sestavine razen črnega smodnika ali bliskovnega praška. Kartuše PAT vsebujejo pirotehnične praške, ki večinoma zagotavljajo pline, potrebne za poganjanje bata. Bat omogoča pritrjevanje (npr. žebljev) ali graviranje znakov v ustrezne materiale. Ta standard se uporablja tudi za kartuše PAT, ki se prodajajo osebam, mlajšim od 18 let, če država članica zaradi majhnega tveganja kartuš PAT to dovoljuje.

EN 16264:2014 (E) 4 1 Scope This European Standard defines the procedures for classifying, testing and labelling of cartridges for powder actuated tools (PAT cartridges), as defined in Clause 3 of this standard. This European Standard does not apply to pyrotechnic articles containing blasting agents and military explosives except black powder and flash composition. PAT cartridges contain pyrotechnic composition(s) delivering mainly gases, intended to propel a piston. The piston propels fasteners (e.g. nails) or drives hard marking characters into appropriate materials. This standard also applies to PAT cartridges sold to persons younger than 18 years, if this is permitted by the member state due to the low hazard of the PAT cartridges. NOTE PAT cartridges can also be used for hard marking tools. Information on cartridge operated fixing and hard marking tools can be found in EN 15895:2011.

If any failure to conduct the procedure correctly is observed, the respective results shall be disregarded and the test shall be repeated. For other aberrant extreme values, the following criterion shall be applied: SIST EN 16264:2014

If ZB1 or ZB2

If only one value is eliminated, the last recorded values shall be disregarded. 18.104.22.168 Sequence of testing steps The test shall be conducted as indicated in the followings points: a) The testing cartridges shall be acclimatized for at least 24 h at an ambient temperature of (+21 ± 1) °C and at relative air humidity of (60 ± 5) %. b) The cartridge holder and the appropriate plunger for the additional volume shall be selected according to the calibre of the cartridge to be fired. c) The bore of the barrel shall be cleaned and lightly lubricated such that the plunger slides in easily. d) A special lubricant as described in f) of this paragraph shall be applied to the diaphragm of the electromechanical transducer. e) The electromechanical transducer shall be screwed onto the transducer holder, applying the tightening torque specified by the manufacturer. f) Before each firing, the channel through which the pressure will be transmitted shall be filled with a silicone-based lubricant of the following specifications: density approximately 1 (g/cm3), penetration 180 to 210 (1/10 mm) (still medium and agitated medium) in accordance with ISO 2137. g) The excess lubricant introduced into the barrel while attaching the electromechanical transducer shall be removed. h) The plunger shall be pushed in as far as it will go, with its flanges positioned opposite to the cartridge so that the cross-shaped opening in the piston is in line with the axis of the electro-mechanical transducer. i) In subsequent firings, care shall be taken that during handling the plunger is not moved – not even slightly – out of position. j) After each firing, the cartridge case shall be ejected and recovered to examine the marks from the firings. k) The plunger shall be recovered and checked to ensure that there are no marks from the firings.
