1 Scope This part of ISO 22827 covers acceptance testing of equipment for 2D manipulation and also, to some extent, movements along the Z-axis. NOTE Welding robots and similar 3D equipment for manipulation are covered by other standards, notably ISO 9283. This part of ISO 22827 specifies two methods for the testing of the accuracy of the moving mechanism. The […]

4 General description Membrane materials are widely used in periodontology and oral and maxillofacial surgery, and have characteristics which are unique to these applications, for example: a) placement in contact with teeth and their supporting tissues; b) prevention of oral mucosal epithelial migration into surgically treated defects; c) predictable loss of structural integrity and mechanical properties over time in oral […]

1 Scope This International Standard specifies a test method for determining the resistance of the tufted portion of anual toothbrushes to deflection. This International Standard is applicable to toothbrushes having a conventional, flat trim design and may not be applicable to toothbrushes with other designs. The results obtained with this International Standard may not correspond to consumer perceptions of the […]

1 Scope This International Standard specifies requirements and test methods for the physical properties of powered toothbrushes in order to promote the safety of these products for their intended use. Specifically excluded are other types of powered oral hygiene devices (such as powered interdental brushes) and manual toothbrushes. 2 Normative references The following referenced documents are indispensable for the application […]

1 Scope This document specifies how a preliminary welding procedure specification is qualified by welding procedure tests. This document is part of a series of standards, details of this series are given in EN ISO 1 5607:2003, Annex A. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for […]

1 Scope This part of ISO 1 5547 gives requirements and recommendations for the mechanical design, materials selection, fabrication, inspection, testing, and preparation for shipment of brazed aluminium plate-fin heat exchangers for use in petroleum, petrochemical and natural gas industries. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 heat transfer area […]

1 Scope This part of ISO 1 1 1 1 1 is intended to be used in conjunction with ISO 1 1 1 1 1 -1 . It specifies significant hazards and corresponding safety requirements and/or measures for preparatory machinery to weaving and knitting. By taking into account the scope of ISO 1 1 1 1 1 -1 as far […]

1 Scope This International Standard specifies the HD-BURN format applied to CD-R/RW discs. The HD-BURN system is capable of recording the information in double density compared to the conventional CD-R/RW disc. It enables the realization of products with high reliability, high speed and interchangeability, and is especially suitable for consumer applications with high cost-performance. This document describes: – the physical […]

1 Scope and object This International Standard applies to composite station post insulators consisting of a load bearing cylindrical insulating solid core made of resin impregnated fibres, a housing (outside the insulating solid core) made of elastomer material (e.g. silicone or ethylene-propylene) and end fittings attached to the insulating core. Composite station post insulators covered by this standard are subjected […]
