You will notice with E12 values that each succeeding value falls within the plus/minus 10% of the previous values.
This stems from the real old days when resistances were stated as within 20% tolerance(accuracy).
Later values of plus/minus 5% tolerance led to the E24 range of resistance.
Quite common today are 2% tolerance metal films types but for general purpose use we tend to stick to E12 values of resistance in either 1%,2%or 5% tolerance.
Cost is the determining factor and many retailers now stock the 2% range of resistance as a standard to accommodate stocking levels and also at reasonably low cost.

你会注意到每一个成功的价值与E12内加值的10% /值减去.
这源于真实的古老的日子都表示20%之内电阻(准确).
后来价值减去5%的宽容以及/ E24导致的阻力.
今天是司空见惯的2%的公差金属薄膜类型,但为通用使用我们倾向于坚持E12价值观的阻力在1%,2%or 5%的宽容.
成本是决定性的因素,许多零售商的2%,现在的股票作为标准来容纳阻力水平,同时袜子合理成本较低.
希望我的回答对你有帮助!呵呵!
