Solid biofuels and pyrogenic biocarbon — Determination of sulfur and chlorine content
ISO 16994:2016 describes methods for the determination of the total sulfur and total chlorine content in solid biofuels. It specifies two methods for decomposition of the fuel and different analytical techniques for the quantification of the elements in the decomposition solutions. The use of automatic equipment is also included in ISO 16994:2016, provided that a validation is carried out as…

Pneumatic fluid power — Test methods for measuring acoustic emission pressure levels of exhaust sile...
This document specifies two methods of measuring the level of acoustic pressure at the outlet of an exhaust silencer:
— the first method, called "steady-state mode", is intended to evaluate the noise level under steady state flow, i.e. constant upstream pressure (steady-state test according to ISO 6358‑1); and
— the second method, called "discharge", is intended to measure the…
