As used by ordnance departments and armories, an Eprouvette is a one piece, fixed elevation mortar used to test the strength of gunpowder. It went out of general use by the middle of the 19th century. In use, a carefully weighed quantity of powder (charge) was placed inside, followed by a standard weight shot. The charge was fired and the distance the shot flew was measured and compared to the expected standard distance. It was first introduced in the middle of the 1600s.

| - イプロゥヴェト試験(イプロゥヴェトしけん、Eprouvette test)は、フランスで発明され17世紀から19世紀まで欧米各国で用いられていた火薬類の性能試験の一種。フランスでは無煙火薬が一般化するまで黒色火薬の性能を判定して等級付けをするために用いられ欧米各国でも採用されていた。 Eprouvetteとはフランス語のÉprouvetteに由来する英単語で、フランス語で試料を意味しており、現代でもフランス語では試料とか試験管などの意味で使用されている。直訳すれば試料試験となるが、英語のサンプルテストとは異なる意味で火薬試験の用語となっている。 (ja)

Eprouvettes were also used to test the strength of small-arms powder, starting in the second half of the 1500s. These evolved into pistol-size devices which were used until the end of the black powder era, at the close of the 1800s. (en)
