Le présent document spécifie les exigences relatives à la sécurité et aux performances des dispositifs d'assistance circulatoire implantables actifs, y compris les exigences des essais de type, des études sur les animaux et des évaluations cliniques. NOTE Le dispositif couramment appelé dispositif médical implantable actif peut en fait être un dispositif unique, une combinaison de…

This document provides guidelines for cost analysis of the use of reclaimed water in industrial cooling systems. This document is intended for new-built industrial cooling systems using reclaimed water as make-up water, in which the reclaimed water originates from industrial wastewater and is generated through wastewater treatment systems for reuse. The source of industrial wastewater is from all…

This document specifies procedures for designing, preparing and using reversed U-bend (RUB) test specimens for investigating the susceptibility of the metal to stress corrosion cracking. The term "metal" as used in this document includes alloys.

Le présent document spécifie les modes opératoires de conception, de préparation et d'utilisation d'éprouvettes d'essai cintrées en U invers (RUB, aussi dénommées « selles de cheval ») permettant d'étudier la sensibilité du métal à la corrosion fissurante sous contrainte. Pour les besoins du présent document, le terme « métal » inclut également les alliages.

Le présent document spécifie un mode opératoire pour la détermination des variations dimensionnelles et de la déformation hors plan susceptibles de survenir lorsque des dalles et des revêtements de sol textiles sont soumis à diverses conditions de mouillage et de chaleur. La méthode est applicable à tous les revêtements de sol textiles et revêtements de sols textiles sous forme de dalles.

This document provides guidelines for various preservation methods for raw goat and sheep skins. The preservation methods are needed to suppress microbiological activity and to maintain the quality of the skins during storage.

This document specifies a test method for determining thermal expansion coefficient up to 2 300 K and the residual stress of chemical vapour deposition (CVD) ceramic coatings (thickness > 0,03 mm) at room temperature. Procedures for test piece preparation, test modes, heat rate, data collection, property calculations and reporting procedures are given. This document applies to CVD ceramic…

This document establishes procedures for measuring the average steady-state pressure in a hydraulic fluid power conduit. It is applicable to the measurement of average steady-state pressure in closed conduits with inside diameters greater than 3 mm, transmitting hydraulic fluid power with average fluid velocities less than 25 m/s and average steady-state static pressures less than 70 MPa. It is…

This document establishes general principles for the measurement of performance parameters under static or steady-state conditions. This document provides guidance on the sources and magnitudes of uncertainty to be expected in the calibration of and measurements using hydraulic fluid power components. It describes practical requirements for assessing the capability of the measuring system, and…

This document specifies a procedure for the determination of the dimensional changes and distortion out of plane likely to take place when textile floor coverings and tiles are subjected to varied water and heat conditions. The method is applicable to all textile floor coverings and textile floor coverings in tile form.
