| Sl.No. | Synosis Points | |
| 1 | The third revision of the standard includes non-fluxed solid wires, a wider range of solder alloys, and additional flux compositions/types beyond rosin fluxes. The revision aligns the flux classification with internationally accepted standards and recognized test methods. | |
| 2 | Title Modification: Changed from "Flux cored solder wire — Specification" to "Solder wire — Solid and flux cored— Specification". | |
| 3 | Expanded Scope: Now covers both solid and flux-cored solder wires, with classification and performance requirements for different flux types: Rosin (RO), Resin (RE), Organic (OR), and Inorganic (IN). | |
| 4 | Chemical Composition Update: Includes both lead-containing and lead-free grades. Covers approximately 30 lead-containing alloys and 31 lead-free solder grades, with provisions for other alloys meeting impurity limits. | |
| 5 | Terminology Clause: Added for clarity. | |
| 6 | Flux Percentage Adjustment: Previously restricted to 2-4 percent; now flexible as per agreement, with specified tolerance limits. | |
| 7 | Dimensions and Tolerances Update: Includes additional recommended sizes with tolerance limits. | |
| 8 | Sampling Clause: Modified for current requirements. | |
| 9 | Testing Frequencies Clause: Manufacturers must test at specified frequencies to ensure process control and product conformity. | |
| 10 | Annex A: Specifies methods for extracting flux from flux cored solder wire for testing. Annex D: Details classification and requirements for fluxes used in solder wire manufacture. Annex E: Procedure for determining flux content in flux cored solder wire. | |
| 11 | Various Annexures for Test Methods Included as per Internationally Accepted Standards and norms: Include tests for spread, flux residue dryness, nominal diameter measurement, copper mirror, copper plate corrosion, non-volatile content, halide content, surface insulation resistance, electrochemical migration resistance, and acid value determination. | |
| 12 | Optional Tests Included: Include spread test, Electrochemical Migration Resistance (ECM) test, and halogen content test | |
