标准范围

原理在于将试验溶液吸入一氧化二氮/乙炔火焰中。测量钡在553.5nm波长下发出的辐射。氯化钾的加入抑制了火焰中钡原子的电离。该方法适用于“可溶”钡含量在约0.05%（m/m）至5%（m/m）范围内的涂层材料。这种方法是争议案件中的仲裁方法。第二版取消并取代了ISO 3856/3-1980，对其进行了全面修订。

The principle consists in the aspiration of the test solution into a dinitrogen monoxide/acetylene flame. Measurement of the radiation emitted by barium at a wavelength of 553,5 nm. The ionization of barium atoms in the flame is suppressed by addition of potassium chloride. The method is applicable to coating materials having "soluble" barium contents in the range of about 0,05 % (m/m) to 5 % (m/m). This method is the referee method in cases of dispute. This second edition cancels and replaces ISO 3856/3-1980, of which it constitutes a thorough revision.
