Iron ores — Sampling and sample preparation procedures
ISO 3082:2017 provides
a) the underlying theory,
b) the basic principles for sampling and preparation of samples, and
c) the basic requirements for the design, installation and operation of sampling systems
for mechanical sampling, manual sampling and preparation of samples taken from a lot under transfer. This is in order to determine the chemical composition, moisture content, size…

Digital living network alliance (DLNA) home networked device interoperability guidelines - Part 1-2:...
IEC 62481-1-2:2017 introduces a number of device classes to identify specific roles that connected endpoints implement in the network. Devices can act as content sources (e.g., Digital Media Servers, Push Controllers), and as content sinks (Digital Media Renderers or Digital Media Players). This document addresses this issue and, specifically, it describes a device class for an Extended Digital…

Metallic powders — Determination of acid-insoluble content in iron, copper, tin and bronze powders
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…
