19、(the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical comm
20、ittee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrote
21、chnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. International Standard ISO10564 was prepared by T

Descriptors: Soldering, solders, sampling, specimen preparation.iv blankBS EN ISO 10564:1997 BSI 11-1998 1 1 Scope This International Standard specifies methods for sampling a consignment
23、of soft solder which is sub-divided into batches and the procedures for the preparation of an analysis sample representative of each batch. 2 Definitions For the purposes of this International Standard, the following definitions apply. 2.1 soft solder metallic filler material which is used to join m
24、etallic parts and which has a melting temperature (liquidus) lower than that of the parts to be joined, and usually lower than 450C 2.2 unit of product item inspected in order to determine its classification as defective or non-defective 2.3 batch collection of units of product, made from a single u
25、niform melt 2.4 consignment quantity of product, consisting of one or more batches, of the same grade delivered at the same time, by the supplier to the purchaser 2.5 batch sample one or more units of product selected at random from the batch and considered, in total, to be representative of the bat
26、ch 2.6 test sample stick stick of solder prepared by melting the whole of, or a representative fraction of, the batch sample and pouring it into a suitably shaped cast iron or aluminium mould 2.7 analysis sample representative sample prepared from the test sample stick and used for the determination
27、 of the chemical composition 3 Principle The procedures given in clause4 are designed to produce an analysis sample representative of each batch of soft solder in the consignment. 4 Sampling 4.1 Unit of product The unit of product used for the sampling shall be as given inTable 1. Table 1 Units of p
28、roduct for various forms ofsolder 4.2 Selection of the batch sample Select the batch sample as follows: a) where the batch consists of up to 4units of product, select all the units; b) where the batch consists of over 4, up to and including 44units of product, randomly select4units of product; c) wh
29、ere the batch consists of n units of product (where n is greater than 44), randomly select0,1n units of product (to the nearest integer above 0,1 n). 4.3 Preparation of the test sample sticks from the batch sample 4.3.1 General Using the batch sample selected in accordance with4.2, prepare test samp
30、le sticks by the method described in either 4.3.2 or 4.3.3, depending on the form in which the soft solder is supplied. 4.3.2 Solder (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 C and100 C a
31、bove the liquidus temperature of the alloy. Stir well and chill-cast test sample sticks, approximately 50g to 100g in mass and not more than 8mm thick, in a cast iron or aluminium mould of the shape given in Figure 1. If the batch sample mass is 50g or less, then pour the whole of the melted sample
32、into one of the cavities in the mould. NOTE 1The material from which the mould is made should be such that it does not cause contamination of the solder samples. NOTE 2No flux is necessary when melting the batch sample, if the units of product are in the cast form. However, the dross should be scrap
33、ed aside before casting the test sample sticks.

34、der (wrought) in the form of wire, pellets, powder or pre-forms From each unit of product in the batch sample (4.2) take, at random, a portion having a nominal mass of10g. Place all the portions taken to represent the batch into a fire clay crucible. Melt the aggregated portions under a thin layer o
35、f flux, such as palm oil, glycerol, rosin or paraffin wax, and heat the melt to between 50 C and 100 C above the liquidus temperature 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 aluminium mould of t
36、he shape given in Figure 1, for every 100 g of melt. If the melted portions have a total mass of less than 50 g, then pour the whole melt into one of the cavities in the mould. NOTE 3The material from which the mould is made should be such that it does not cause contamination of the solder samples.
37、NOTE 4For solder forms containing an integral flux, the flux cover may be omitted when melting the portions. NOTE 5For powders, the recommended flux is activated rosin (e.g. type 1.1.3, as defined in ISO9454-1:1990, Soft soldering fluxes Classification and requirements Part1:Classification, labellin
38、g and packaging). NOTE 6If the mass of the consignment is too small for this procedure to be practicable, then the procedure for sampling should be agreed between the supplier and the purchaser. Figure 1 Mould for casting the test sample sticksBS EN ISO 10564:1997 BSI 11-1998 3 4.4 Preparation of th
39、e analysis sample Cut each test sample stick, obtained as described in4.3, in half transversely and take sufficient transverse slices from the middle portion of each stick to give a total mass of between 10g and 20g. Place all the slices into a clean fire clay crucible and add flux (as listed in4.3.
40、3). Melt the slices and heat the melt to between 50 C and 100 C above the liquidus temperature of the alloy. Stir well and invert the crucible at a height of approximately 50cm above a dry, clean, smooth steel plate, having dimensions greater than50cm 50cm. The “splash” sample obtained, which should
41、 be in the form of a foil suitable for cutting with scissors, constitutes the analysis sample representative of the batch. 4.5 Testing of individual units of product (for wrought forms only) As an alternative to combining the units of product in the batch sample, as in4.3.2 and 4.3.3, each unit of p
42、roduct selected from the batch by the procedure given in4.2 may be analysed individually. In this case, prepare the analysis sample for each individual unit of product in accordance with the procedures given for the batch sample in4.3.2 or4.3.3 (as appropriate) and in4.4. NOTE 7If individual units o
43、f 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 are found to fail on analysis, then the whole batch should be rejected. 5 Preservation of the analysis sample Cut the “splas
44、h” 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 required in a sealed airtight container, having a label giving full details of the origin of the sample.BSI 389 Chiswick High Road London W4 4AL | | | | | | | | |
