This document is applicable to 2-way or multi-way ball valve manufactured with thermoplastic materials to be used for the transport of pressurized water whether or not intended for human consumption (domestic systems) for applications in buildings and utility branches.               NOTE The two-way valve is generally used for sectioning and control, the multi-way one to divert or mix the flows;…

This international standard provides guidelines for the classification and performance of leather upholstered products. This international standard is applicable for products made of leather upholstered for all levels of production. This international standard is applied, if the upholstered material is made of leather or rather is a leather semifinished product in the sense of ISO 15115.

This standard establishes the calculation procedures for determining specification limits for external andinternal cylindrical involute gearing with constant gear ratio when the desired tooth thickness is known.This standard also shows the relationships between backlash and the tooth thickness, centre distance,and tooth deviations in a pinion and gear mesh.

This standard specifies 'safety and quality' requirements for detection and avoidance (DAA) systems used between UAS and other objects including aircraft. The standard includes the requirements of radar and optical sensors used for DAA and was derived to meet the requirements for UAS operations involving DAA set out in ISO 21384-3.

This document specifies test methods applicable to prestressing steel (bar, wire or strand) for concrete. This document does not cover the sampling conditions that are dealt with in the product standards.

ISO 17633:2017 specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels.…

This International Standard specifies methods for the determination of major and minor element concentrations in solid recovered fuels after digestion by the use of different acid mixtures and by addition of a fluxing agent for SRF ash and is applicable for major and minor/trace elements: Major elements: Aluminium (Al), Calcium (Ca), Iron (Fe), Potassium (K), Magnesium (Mg), Sodium (Na),…

Manufacturers of bar code equipment and users of bar code technology require publicly available standard symbology specifications to which they can refer when developing equipment and software. ISO/IEC 15420:2009 specifies the requirements for the bar code symbology known as EAN/UPC. It specifies EAN/UPC symbology characteristics, data character encodation, dimensions, tolerances, decoding…

This document is applicable to pure cultures of STEC. The present standard describes the characterization of STEC strains, isolated from any source. In particular, the characterization of STEC strains described here regard: - subtyping of the Stx-coding genes; - determination of the presence of eae gene; - determination of the presence of aggR gene; - identification of the presence of genes…

This standard specifies the characterization of ceramic slurry for use as feedstock in vat photopolymerization additive manufacturing (AM) process. The characterization includes the composition and properties of the slurry, such as solids content, dynamic viscosity, particle size distribution, chemical composition, and solid dispersion stability. This standard also provides available methods…
