Metallic and other inorganic coatings — Determination of thermal conductivity of thermal barrier coa...
This document specifies a method for determining the thermal conductivity of ceramic top coat (TC) constituting thermal barrier coating (TBC) subjected to heat treatment, in a direction normal to the coating surface, from room temperature up to 1 000 °C.
This document specifies requirements for the components and method of installation of pressurized irrigation system control heads, referred to hereinafter as irrigation control heads, with a nominal size of up to and including 200 mm (nominal size of an irrigation control head or nominal size of a component).
This document is applicable only to the above-ground components of irrigation control…
Fine bubble technology — Agricultural applications — Part 3: Guidelines for the minimum viable numbe...
This document demonstrates guidelines for promoting the germination of barley seeds with a lower number concentration of ultrafine bubbles (UFB). This is achieved by taking the data concerning the germination ratio of barley seeds conforming to ISO 23016-2 as a starting point and then evaluating the minimum number concentration range of ultrafine bubble water necessary for promoting the effect on…
