Bases for design of structures — Actions due to the self-weight of structures, non-structural elemen...
Defines the actions due to the self-weight of structures, non-structural elements and stored materials and gives the numerical values of their densities. These actions are to be determined by multiplying the densities by the gravitational acceleration and by the actual volume. The actions caused by the weight of the earth placed on the structures are similarly calculated.
Specifies dimensional requirements necessary for the mounting of injection nozzle holders in diesel engines. The location of the fuel inlet and leak-off connections are not defined since they vary according to the particular application. A figure illustrates the shape and reference quantities of concern. Preferred shank lengths are given in table 2.
Fluid systems — Sealing devices — O-rings — Part 3: Quality acceptance criteria
This part of ISO 3601 defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these imperfections, and it is also applicable to O-rings to be used in aerospace construction. Gives quality grades and definitions, and the table contains categories of surface imperfections together with schematic illustrations of these imperfections. An annex gives…
Sewing machines needles — Fitting dimensions — Tolerances and combinations
ISO 8239 specifies the fitting dimensions of needles and needle holders. It defines general terms for sewing machine needles and specifies the tolerances for their fit in the needle holder. In addition to the rangers of dimensions for the nominal shank diameter and the length from butt to eye, ISO 8239 also indicates the preferred combinations of these two dimensions. In order to ensure the…
1. Scope
1.1 This Standard specifies a set of technical requirements and test methods for solar collectors and covers component materials, materials performance, operating performance, and marking requirements.
1.2 This Standard applies to solar collectors used for conver ting solar radiation into thermal energy. It covers only collectors with an aperture area of not less than 0.5 m²…
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.
