Soft soldering fluxes — Test methods — Part 3: Determination of acid value, potentiometric and visua...
This document specifies two methods for the determination of the acid value of a flux of types 1 and 2 only, as defined in ISO 9454‑1.
Method A is a potentiometric titration method and is to be considered as the reference method.
Method B is an alternative, visual end‑point, titration method.
Soft soldering fluxes — Test methods — Part 16: Flux efficacy test, wetting balance method
This document specifies a method for the assessment of the efficacy of a soft soldering flux, known as the wetting balance method. It gives a qualitative assessment of the comparative efficacy of two fluxes (for example, a standard and a test flux), based on their capacity to promote wetting of a metal surface by liquid solder. The method is applicable to all flux types in liquid form classified…
Petroleum products — Fuels (class F) — Considerations for fuel suppliers and users regarding marine ...
This document addresses quality considerations that apply to marine fuels in view of the implementation of maximum 0,50 mass % S in 2020 and the range of marine fuels that will be placed on the market in response to the international statutory requirements to reduce exhaust gas emissions. It defines general requirements that apply to all 0,50 mass % sulfur (S) fuels and confirms the applicability…
Hardmetals — Sampling and testing of powders using sintered test pieces
This document specifies procedures for the sampling and testing of powder mixtures for the manufacture of hardmetals, using sintered test pieces. It also covers the preparation of test pieces.
