1. Scope 1.1 This Standard outlines a means for certifying eligible welding inspectors by examination in one of three levels. It describes the responsibilities associated with each level and the basic technical functions of welding inspectors. This Standard also outlines a means of registering welding inspection trainees. Note: The certification document should indicate in relation…

This International Standard specifies signalling interworking between "QSIG" and "H.323" in support of the call transfer supplementary services within a Corporate telecommunication Network (CN). "QSIG" is a signalling protocol that operates at the Q reference point between Private Integrated Services eXchanges (PINX) within a Private Integrated Services Network (PISN…

1. PURPOSE AND SCOPE 1.1 This method rates textile materials for thermal resistance and insulation when exposed to a convective energy level of 83 ± 2 kW/m2 for a short duration. 1.2 It is applicable to woven fabrics, knit fabrics, battings, and nonwoven fabrics intended for use as clothing for protection against a chance, short exposure to open flames. It is not intended for evaluating…

1. SCOPE 1.1 This Standard specifies the requirements for factory made rigid expanded polystyrene insulation in the form of pipe covering and boards with or without facings or coatings made by moulding (EPS) or extrusion (XPS) of expandable polystyrene beads. This Standard does not apply to laminated products manufactured with any type of rigid board facer including fibreboard, perlite…

1. SCOPE 1.1 This Standard provides the requirements and test methods for spray-applied rigid polyurethane cellular plastics, medium density, used as a thermal insulation for both building and non-building applications, whether applied on a building site or in a prefabrication (manufacturing) facility. The material is also known as foamed in-situ insulation. 1.2 The spray-applied…

1. SCOPE 1.1 This standard applies to fabric of four different masses per unit area (145 g/m², 150 g/m², 160 g/m² and 170 g/m²) made from yarns that are a blend of 65% polyester and 35% cotton. 1.2 The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety…

1. Scope 1.1 This standard applies to polyester/cotton twill fabric with a durable press finish of three different masses per unit area: 170 g/m², 235 g/m² and 255 g/m². 1.2 The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its…

This International Standard - provides definitions for the transmitted field characteristics of focusing transducers for applications in medical ultrasound; - relates these definitions to theoretical descriptions, design, and measurement of the transmitted fields of focusing transducers; - gives measurement methods for obtaining defined characteristics of focusing transducers; - specifies beam…
