SOFT SOLDERING FLUXES - TEST METHODS - PART 11: SOLUBILITY OF FLUX RESIDUES (ISO 9455-11:1991, IDT)
MS ISO 9455-11:2009
Status : Original
Format : PDF

This Malaysian Standard specifies a qualitative method for assessing the solubility of flux residues in a selected solvent. The method is applicable to all fluxes of Type 1, as defined in IS0 9454-l. ....Read more

NOTE 1 This test gives no assurance that post-cleaning residues, which may be present in sufficiently small amounts to pass the test, will not be detrimental to the soldered assembly in the long term.

This Malaysian Standard specifies an ebulliometric method for the determination of the content of non-volatile matter in soft soldering fluxes especially for those containing solvents of relatively hi ....Read more gh volatility, such as propan-2-ol. The method is applicable only to fluxes with a non-volatile content of 10% or more.

NOTE 1 For the determination of the content of nonvolatile matter of liquid fluxes of these classes, where the solvent has a lower volatility than propan-2-ol, the method given in IS0 9455-1 should be used.

SOFT SOLDERING FLUXES - TEST METHODS - PART 6: DETERMINATION AND DETECTION OF HALIDE (EXCLUDING FLUORIDE) CONTENT (ISO 9455-6:1995, IDT)
MS ISO 9455-6:2009
Status : Original
Format : PDF

his Malaysian Standard specifies three quantitative methods for the determination of the ionic halide (excluding fluoride) content of soldering fluxes. Halides are calculated as chlorides. A useful qu ....Read more alitative test method for the detection of ionic halides is also described.

Method A is a potentiometric titration method for the determination of halide (excluding fluoride) content and is applicable to flux classes 1 and 2, defined in ISO 9454-1. This method, which is to be considered the reference method for these fluxes, is suitable for halide contents generally within the range 0.05 % (m/m) to 2 % (m/m) in the non-volatile matter of the flux.

Method B is a titration method for the determination of the total halide (excluding fluoride) content of water-soluble fluxes. lt is applicable to flux classes 2.1.2.A and 3.1 .l .A, as defined in ISO 9454-1.

Method C is a titration method for the determination of the halide (excluding fluoride) content of water soluble fluxes containing Ph

PAPER - DETERMINATION OF LIGHT SCATTERING AND ABSORPTION COEFFICIENTS (USING KUBELKA-MUNK THEORY) (ISO 9416:2009, IDT)
MS ISO 9416:2010
Status : Original
Format : PDF

This Malaysian Standard specifies a method for the calculation of light-scattering and light-absorption coefficients based upon diffuse reflectance measurements made under the conditions specified in ....Read more ISO 2469 using the colour matching function y(?) and CIE illuminant C.

It is emphasised that the strict evaluation of the light-scattering and light-absorption coefficients requires conditions which cannot be achieved with the instrumentation specified here. The values obtained by application of this Malaysian Standard are dependent on the application of the Kubelka-Munk equations, not to full reflectance data but to reflectance factor data obtained using the specified d/0° geometry and a gloss trap.

The use of the method is restricted to white and near-white uncoated papers with an opacity less than about 95 %. Paper that has been treated with a fluorescent dyestuff or that exhibits significant fluorescence can only be dealt with if a filter with a cut-off wavelength of 420 nm is used
