Textile Test Methods Linear Density of Yarn in SI Units
Determines the relationship between the length and mass of the
yarn being tested, using SI Units. The SI derived unit is the
tex, which is defined as the mass in grams per kilometre.
Multiples or submultiples of the tex may be used, as appropriate.
Glass — Viscosity and viscometric fixed points — Part 3: Determination of viscosity by fibre elongat...
A method of determining the dynamic viscosity of glass by measuring the elongation a glass fibre under a defined uniaxial stress. In addition the viscosity-temperature relationship and the dependence of the viscosity on the thermal history can be checked. The theoretical basis relation and the apparatus including the method of measuring are specified.
Glass — Viscosity and viscometric fixed points — Part 6: Determination of softening point
The temperatur above which the glass is capable of most forming operations is determined by measuring the elongation of a round glass fibre under its own weight. Closely defines requirements for the test specimen, procedure and apparatus lead to optimum repeatability of the specified temperature point. The furnace is specified with essential aspects.
Building construction — Jointing products — Determination of extrudability of sealants using standar...
Applies to all sealants regardless of the kind of packages in which they are supplied or from which they are applied to the joint in buildings. A defined volume of sealant is extruded from a standardized device under defined conditions by means of compressed air and recorded depending on time.
Road vehicles — Lighting and light signalling devices — Vocabulary
Defines terms in the three ISO-languages English, French, and Russian relating to lighting and light signalling devices for road vehicles as defined in ISO 3833 (in certain countries and international bodies, the term "light" is sometimes used instead of "lamp"). Alphabetical indexes in English, French, and Russian are also included.
Thermal insulation — Heat transfer conditions and properties of materials — Vocabulary
Defines terms used in the field of thermal insulation to describe heat transfer conditions, such as steady state, non-steady state, periodic state, transient state and heat transfer, and properties of materials.
