phenolphthalein testとは 意味・読み方・使い方

Thereafter, the conductor 6 is detached from the conductor pulling device 1, subjected to heating treatment, and dipped into a test liquid formed by dropping phenolphthalein solution into brine, and a DC voltage is applied by using the conductor 6 as a negative pole and the test liquid as a positive pole, and a current leaking to the outside of the insulation coating is detected.例文帳に追加

その後、導線引張装置１から導線６を取り外し、加熱処理した後、フェノールフタレイン溶液を食塩水に滴下した試験液中に浸し、導線６を−極、試験液を＋極にして直流電圧を加えて絶縁被膜の外部に漏れる電流を検出する。 - 特許庁
