Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for total electrical co...
This document specifies the test method for the determination of total electrical conductivity of conductive fine ceramics by the DC (direct current) four-terminal method. The test method applies to conductive fine ceramics which have an ionic transference number of 0,01 or less. The applicable conductivity range is from 1 S cm−1 to 1 000 S cm−1 and the temperature range is up to 1 000 °C. The…
Solid biofuels — Fuel specifications and classes — Part 6: Graded non-woody pellets
This document determines the fuel quality classes and specifications of graded non-woody pellets. This document covers only non-woody pellets produced from the following raw material (see ISO 17225‑1:2021, Table 1):
— 2 Herbaceous biomass
— 3 Fruit biomass
— 4 Aquatic biomass
— 5 Biomass blends and mixtures
NOTE 1 Herbaceous biomass originates from plants that have a non-woody stem…
Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for air-purification pe...
This document specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films on the surface, usually made from semiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under irradiation with long-wave ultraviolet (UV)…
