GB/T 8411的本部分適用于電絕緣用陶瓷、玻璃陶瓷、玻璃結合云母和玻璃材料。本部分規(guī)定了試驗方法,目的在于用這些方法測出試樣所用材料的典型性能參數(shù)。在多數(shù)情況下,電絕緣陶瓷部件的尺寸和形狀與試樣相差很遠,因此這些測試所得出的結果僅是實際部件特性的指導性參數(shù)。對試樣成型和試樣處理方法的要求在相關處討論。
本標準規(guī)定了巖心的鉆取、處理、保存及巖心分析的準備、測試方法、技術要求及編寫報告的格式、本標準適用于在油氣藏勘探、開發(fā)過程中,對鉆井取心及井壁取心巖樣的測試分析,其他巖心的分析亦應參照執(zhí)行、
本標準規(guī)定了低壓絕緣子瓷件的技術要求、試驗、包裝和標志的一般要求。本標準適用于直流電壓低于1000V的或交流電壓低于1000V、頻率不超過lOOHz的架空電力線路、電氣裝置和設備上使用的絕緣子瓷件。本標準不適用于在有破壞瓷及釉的介質(氣體或液體)中工作的瓷件。
This European standard specifies requirements and test methods for the substances and materials used in chemical toys (sets) other than experimental sets.
