本标准规定了评估核查标准(CS)材料的一次检测结果与其标准值(ARV)之间的差异,并确定相应可接受的公差区间,估算单一测试结果落在公差区间外概率的方法。 本标准适用于产生连续性数值结果的实验室测试方法有无偏倚的判定,不适用于在现场精密度或重复性条件下,通过同一个CS材料来获得多个测试结果的评估。

This part of IEC 60068 outlines test Td@ applicable to surface mounting devices (SMD). This standard provides procedures for determining the solderability and resistance to soldering heat of devices in applications using solder alloys@ which are eutectic or near eutectic tin lead (Pb)@ or lead-free alloys. The solder bath method is applicable to SMDs designed for flow soldering and SMDs designed for reflow soldering when the solder bath (dipping) method is appropriate. The reflow method is applicable to the SMD designed for reflow soldering@ to determine the suitability of SMDs for reflow soldering and when the solder bath (dipping) method is not appropriate. The objective of this standard is to ensure solderability of component lead or termination. In addition@ test methods are provided to ensure that the component body can resist against the heat load to which it is exposed during soldering. NOTE 1 For specific components other test methods may exist. NOTE 2 Test Td does not apply to printed wiring board (PWB)@ see IEC 61189-3. NOTE 3 Specific through-hole devices (where the device supplier has specifically documented support for reflow soldering) are also included in this standard.
