标准范围

ISO 3506-4:2009规定了在10°C至35°C的环境温度范围内进行试验时，由奥氏体、马氏体和铁素体钢级耐腐蚀不锈钢制成的自攻螺钉的机械性能。在较高或较低的温度下，性能会有所不同。根据ISO 1478，它适用于螺纹从ST2,2到ST8（包括ST8）的自攻螺钉。它不适用于具有特殊性能（如可焊性）的螺钉。

ISO 3506-4:2009 specifies the mechanical properties of tapping screws made of austenitic, martensitic and ferritic steel grades of corrosion-resistant stainless steels, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures.It applies to tapping screws with threads from ST2,2 up to and including ST8, in accordance with ISO 1478.It does not apply to screws with special properties such as weldability.
