28、 start temperature and a solidification start temperature. The fusion start temperature is measured by using a differen- tial scanning calorimetry (DSC) or a differential thermal analysis (DTA) and fur- ther a solidification start temperature is measured by using the cooling curve of a fused solder.

Differential thermal analysis (hereafter referred to as “DTA”) Apparatus and equipment The apparatus and equipment to be used for a test shall be principally in accordance with JIS K 7121, and shall be as follows: 5.2.1 DSC apparatus and DTA apparatus The apparatus shall have two con- tainer hold
31、ers whose heat capacities are equal and have a structure capable of be- ing heated and cooled by the same heat exchange conditions. The input-compensating DSC shall have a structure capable of measuring a dif- ference of applied heat energy per unit time between a sample and a reference ma- terial s
32、o that a temperature of the sample and that of the reference materials become the same. The heat flux DSC shall have a structure so that a temperature difference be- tween the sample and the reference material is proportional to a difference between inputs in heat energy per time. a) Heating velocit

34、from being eroded with the sample. The container made of aluminium is generally used. Recorder A recorder shall be able to continuously record a DSC curve or a DTA curve. b) c) d) e) Noise level A noise level shall be S 1/10 of a peak height. 5.2.2 Appliance An appliance shall be as follows: a) Gas
