Описание (английский):

This part of ISO 9455 specifies a method for the determination of the efficacy of a soft soldering flux. The method is known as the solder spread method of filler metal and is applicable to all flux classes defined in ISO 9454-1. NOTE An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, known as the wetting balance method, is specified in ISO 9455-16.[3]

Overview

ISO 9455-10:2012 specifies a laboratory method to determine the efficacy of soft soldering fluxes using the solder spread method (also called the flux efficacy test). The method measures how well a flux promotes wetting and spreading of a defined filler metal on a prepared test surface. It is applicable to all flux classes defined in ISO 9454-1 and is intended for quality control, product development and comparative evaluation of flux performance.

Keywords: ISO 9455-10, soft soldering fluxes, flux efficacy test, solder spread method, flux testing.

Key topics and requirements

Test principle: A cleaned brass test plate is dosed with a fixed amount of flux and a standard solder sample; the plate is lowered onto a molten solder bath so the solder melts and spreads. The spread area (or calculated ratio of spread) quantifies flux efficacy.

Test specimens and materials:

Brass plates: 40 mm × 40 mm, 0.5 mm thick, alloy CuZn37 or CuZn40 (10 plates per flux).
Solder sample: 1 mm diameter wire, 0.49–0.50 g, wound into a flat spiral.
Flux dosing: 0.025 ml (liquid) or 0.025 g (paste/solid) measured by microsyringe or balance.

Standard solder grades and temperatures:

Sn60Pb40 at 235 °C ± 3 °C
Sn96Ag3Cu1 at 255 °C ± 3 °C
Other alloys/temperatures by agreement.

Preparation & cleaning: Degrease in acetone, treat in an acid preparation solution (specified in the standard), rinse, dry-procedure includes safety warnings for corrosive reagents.

Measurement & expression of results:

Measure spread area with a planimeter or determine height and compute spread ratio.
Report arithmetic mean and standard deviation for 10 replicates.
Test report must include sample ID, solder grade, test temperature, area/ratio results and any deviations.

Precision data: Interlaboratory precision (repeatability/reproducibility) is provided for different flux types; Annex A gives a method to prepare standard reference rosin-based fluxes for comparison.

Applications and users

Flux manufacturers for product development and batch quality control.

Electronics assemblers and PCB manufacturers evaluating flux performance for soldering processes.

Independent test laboratories performing standardized flux efficacy testing.

R&D teams comparing halide-activated vs. non-activated fluxes and leaded vs. lead-free solder interactions.

Practical benefits include objective comparison of wetting performance, validation of flux claims, and conformity testing in procurement or regulatory contexts.
