1.1本规程涵盖了光谱化学分析中有用的许多特定石墨电极形状和尺寸。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 ====意义和用途====== 本规程旨在作为使用石墨电极的光谱化学方法的参考。方法应使用并参考本规程中的一种电极形状，但如果不可能，则该方法应包括所用特定形状的电极规格。 在方法中应参考本规程，在试剂和材料部分包括如下声明: 石墨电极 — 电极应为高纯度石墨，并符合规程E 130中描述的类型（插入本方法的名称）。

1.1 This practice covers a number of specific graphite electrode shapes and sizes that are useful in spectrochemical analysis. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. ====== Significance And Use ====== This practice is intended as a reference for spectrochemical methods that utilize graphite electrodes. Methods should employ and reference one of the electrode shapes in this practice, but if this is not possible, the method should include electrode specifications for the specific shape used. This practice should be referred to in a method by including a statement such as the following in the section on Reagents and Materials: Graphite Electrodes — The electrode(s) shall be of high-purity graphite and conform to type(s) (insert designation from this method) as depicted in Practice E 130.
