ISO 4496:2017 specifies methods for determining, in iron, copper, tin and bronze powders, the approximate content of non-metallic materials which are insoluble in the ordinary mineral acids. The insoluble matter referred to is generally considered to be acid-insoluble silica and silicates, carbides, alumina, clays or other refractory oxides which are either present in the raw material from which the powders are manufactured or introduced during the manufacturing process.
Abstract
Overview
EN ISO 4496:2017 (ISO 4496:2017) defines laboratory methods to determine the acid‑insoluble content in metallic powders - specifically iron, copper, tin and bronze powders. The standard is intended for lubricant‑free powder metallurgy materials and quantifies non‑metallic, acid‑resistant impurities (for example silica, silicates, carbides, alumina, clays and other refractory oxides) either originating from raw materials or introduced during manufacture.
Key topics and technical requirements
- Field of application: lubricant‑free iron, copper, tin, bronze and copper‑tin (bronze) powders.
- Sampling and test portions: analysis on two test portions; typical test portion mass ≈ 5 g.
- Equipment and accuracy: laboratory balance with accuracy ±0.0001 g, glass filtering funnel, ashless filter paper (residual ash
