The level of water stress (freshwater withdrawal as a proportion of available freshwater resources) is steadily increasing worldwide. A single use of water is increasingly perceived as an underutilization of a valuable resource and as an environmentally unsustainable practice. Population growth is driving an increasing competition for freshwater between agriculture and urban areas, as well as…

This International Standard is intended to standardize the implementation of reclaimed water for scenic environmental uses by regulating the water quality and quantity, guiding the progress of planning, operating, and management. This International Standard is applicable to practitioners and regulatory authorities who propose to implement principles and guidelines on the implementation of…

This international standard applies to suspension diaphragms designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface. This international standard does not detail other components of pneumatic suspension assemblies or control systems such as air reservoirs, frames, stiffeners,…

This International standard specifies graphical symbols for diagrams for general application. The standard constitutes a symbol library, from which users can use the symbols or created symbol examples for use in diagrams. Graphical symbols for fluid power objects are covered by ISO 1219-1 Graphical symbols for electro technical objects are covered by IEC 60617 DB.

This International Standard defines the principles used to determine loads and the induced environment during the service life of a space flight vehicle and its components, taking account of the notions of probability, combined loads, corresponding safety factors and lifecycle.

This international standard specifies the requirements for factory-made rigid nano-microporous insulation, for use in industrial applications. This document specifies insulation that exhibits thermal insulating performance through nano-sized-pore composite material. The material comprises a blend of inorganic powder, fibres and opacifiers. The products are delivered as board or pipe section type…

This International Standard specifies a procedure for determining the plain-pin bearing strength of fibre-reinforced plastic composites. The method described in this International Standard is applicable to fibre-reinforced plastic composites with either thermoset or thermoplastic matrices.

This International Standard specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on pipes made of: - unplasticized Polyamide (PA-U 180). Note: PA-U 180 follows ISO 16486-1 and covers both PA-U11 180 and PA-U12 180
