Annotation of standard text ČSN 668070 (668070):

Norma stanoví metody pro stanovení detonační schopnosti všech druhů průmyslových trhavin roznětem jednotným počinem. Podstata zkoušky: Detonační schopnosti se rozumí schopnost trhaviny detonovat za předepsaných podmínek spolehlivě a beze zbytku po celé délce nálože. Při stanovení detonační schopnosti podle této normy se používá k roznětu zkoušené trhaviny jednotného počinu tělískem z lisovaného pentritolu (metoda A). Trhaviny, u nichž je předepsán roznět rozněcovadlem s iniciační mohutností nejméně stejnou jako má rozbuška č. 8, musí při stanovení detonační schopnosti vyhovovat i další zkoušce roznětem rozbuškou č. 3, nebo rozbuškou č. 8 u trhavin, u nichž výrobce citlivost k rozbušce č. 8 nezaručuje (metoda B). Norma výslovně v čl.2.3 stanoví: "Při zkouškách musí být dodrženy bezpečnostní předpisy pro zkoušky výbušnin podle ČSN 01 8003 a ČSN 66 8002." Postupy při provádění normalizovaných zkoušek jsou podrobně popsány. ČSN 66 8070 byla vydána v říjnu 1993. Nahradila ČSN 66 8070 z 9.2.1977
