标准摘要
[中文适用范围]： 本国际标准规定了测定氧化铝在 300℃加热时的质量损失和在 1000℃进一步灼烧时的质量损失的方法。 按照行业惯例，这些质量损失通常分别称为“水分 (MOI)”和“烧失量 (LOI)”。 该方法适用于 300 °C 时质量损失为 0.2 % 至 5 % 以及 1 000 °C 时质量损失为 0.1 % 至 2 % 的煅烧氧化铝。 该方法允许在“收到时”的基础上处理样品，以确定氧化铝样品中的实际 MOI 和 LOI。 为了在不需要“收到的”结果的情况下提高分析精度，可以在分析之前对样品进行“空气平衡”。 “空气平衡”可以极大地影响 MOI 结果并显着改变 LOI 结果。 “空气平衡”程序及其效果在附录 A 中讨论。 还讨论了仪器方法。 [外文原描述]： ISO 806:2004 specifies a method for the determination of loss of mass on heating of aluminium oxide at 300 °C and further loss of mass on ignition at 1 000 °C. By industry convention, these mass losses are often referred to as "moisture (MOI)" and "loss on ignition (LOI)" respectively. This method is suitable for calcined alumina in the range 0,2 % to 5 % loss of mass at 300 °C and 0,1 % to 2 % loss of mass at 1 000 °C. This method provides for samples to be treated on an "as-received" basis for determination of actual MOI and LOI in alumina samples. To improve precision of analysis in cases where "as-received" results are not required, samples can be "air-equilibrated" prior to analysis. "Air-equilibration" can greatly affect MOI results and significantly alter LOI results. The "air-equilibration" procedure and its effects are discussed. Instrumental methods are also discussed.
