标准范围

规定方法的原理是，在最初在15°C至25°C温度下用690 kPa的氧气填充的压力弹中氧化样品，在98°C至102°C的温度下加热，以规定的间隔读取压力或连续记录，直到达到断点。样品达到该点所需的时间是在试验温度下观察到的诱导期，从中可以计算100°C下的诱导期。该方法仅适用于成品形式的航空和汽车汽油。

The principle of the method specified is oxidizing the sample in a pressure bomb initially filled at 15 °C to 25 °C with oxygen at 690 kPa, heating at a temperature between 98 °C and 102 °C, reading the pressure at stated intervals or recorded continuously until the breakpoint is reached. The time required for the sample to reach this point is the observed induction period at the temperature of test, from which the induction period at 100 °C may be calculated. The method is applicable for aviation and motor gasolines in their finished form only.
