11、IS0 10564 : 1997 4.3 Preparation of the test sample sticks from the batch sample 4.3.1 General Using the batch sample selected in accordance with 4.2, prepare test sample sticks by the method de- scribed in either 4.3.2 or 4.3.3, depending on the form in which the soft solder is supplied. 4.3.2 Sold

12、er (cast or wrought) in ingot, slab, bar, stick or rod form Melt the whole batch sample (4.2) in a clean iron or fire clay crucible and heat it to between 50 OC and 100 C above the liquidus temperature of the alloy. Stir well and chillcast test sample sticks, approxi- mately 50 g to 100 g in mass an

13、d not more than 8 mm thick, in a cast iron or aluminium mould of the shape given in figure 1. If the batch sample mass is 50 g or less, then pour the whole of the melted sam- ple into one of the cavities in the mould. 110 NOTES 1 The material from which the mould is made should be such that it does

14、not cause contamination of the solder samples. 2 No flux is necessary when melting the batch sample, if the units of product are in the cast form. However, the dross should be scraped aside before casting the test sam- ple sticks. 4.3.3 Solder (wrought) in the form of wire, pellets, powder or prefor

15、ms From each unit of product in the batch sample (4.2) take, at random, a portion having a nominal mass of 10 g. Place all the portions taken to represent the batch into a fire clay crucible. Melt the aggregated portions under a thin layer of flux, such as palm oil, glycerol, rosin or paraffin wax,

16、and heat the melt to between 50 “C and 100 OC above the liquidus tem- perature of the alloy. Stir well and chill-cast one test sample stick, approximately 50 g to 100 g in mass and not more than 8 mm thick, in a cast iron or alu- minium mould of the shape given in figure 1, for every 6 4 A - Dimensi

If the melted portions have a total mass of less than 50 g, then pour the whole melt into one of the ca

18、vities in the mould. NOTES 3 The material from which the mould is made should be such that it does not cause contamination of the solder samples. 4 For solder forms containing an integral flux, the flux cover may be omitted when melting the portions. 5 For powders, the recommended flux is activated

20、tween the supplier and the pur- chaser. 4.4 Preparation of the analysis sample Cut each test sample stick, obtained as described in 4.3, in half transversely and take sufficient transverse slices from the middle portion of each stick to give a total mass of between 10 g and 20 g. Place all the slice

21、s into a clean fire clay crucible and add flux (as listed in 4.3.3). Melt the slices and heat the melt to between 50 “C and 100 “C above the liquidus tem- perature of the alloy. - E - - = - - - BS EN IS0 10564 : 1997 Stir well and invert the crucible at a height of approx- imately 50 cm above a dry,

22、 clean, smooth steel plate, having dimensions greater than 50 cm x 50 cm. The “splash“ sample obtained, which should be in the form of a foil suitable for cutting with scissors, con- stitutes the analysis sample representative of the batch. 4.5 Testing of individual units of product (for wrought for

23、ms only) As an alternative to combining the units of product in the batch sample, as in 4.3.2 and 4.3.3, each unit of product selected from the batch by the procedure given in 4.2 may be analysed individually. In this case, prepare the analysis sample for each individual unit of product in accordanc

24、e with the procedures given for the batch sample in 4.3.2 or 4.3.3 (as appropriate) and in 4.4. NOTE 7 If individual units of product are found not to comply with the chemical composition requirements, then they should be individually rejected. If more than 10 % of the units of product in the batch

25、are found to fail on analysis, then the whole batch should be rejected. 5 Preservation of the analysis sample Cut the “splash“ sample (4.4) into small pieces with scissors, degrease them with acetone and dry in a stream of warm air. Keep the sample pieces until re- quired in a sealed airtight contai

26、ner, having a label giving full details of the origin of the sample. 3 STD-BSI BS EN IS0 L05b4-ENGL 1777 Lb24bb7 Ob057b2 b75 BS EN IS0 I . . - 10564 : 1997 BSI 389 Chiswick High Road London w4 4AL 1 BSI - British Standards Institution BSI is the independent national body responsible for preparing Br
