This document specifies the Contrast–Resolution test chart, the requirements on the printing process needed to reproduce this test chart, the required characteristics of a high resolution scanner needed to digitize the information reproduced on printed test charts, and the requirements on the interpretation of this digitized data. It also specifies the resolution-score method for evaluating the…
Plastiques — Détermination de la conductivité thermique et de la diffusivité thermique — Partie 4: M...
Le présent document spécifie une méthode de détermination de la diffusivité thermique d’un disque plein mince en plastique suivant la direction de l’épaisseur par la méthode flash lumineux. Cette méthode est fondée sur le mesurage de l’élévation de température sur la face arrière d’une éprouvette sous forme de disque mince due à une courte impulsion énergétique sur la face avant.
La méthode est…
Ergonomics of the thermal environment — Management of working conditions in hot environments
This document adopts an approach where actions, particularly control measures and medical supervision, are specified as a function of the class of severity of the potential effects. It provides instructions for appropriate management practices for hot workplaces and describes:
— a procedure for managing work in hot environments;
— guidelines on how to apply the different International…
Plastics — Determination of thermal conductivity and thermal diffusivity — Part 4: Light flash metho...
This document specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the light flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face.
The method is applicable to homogeneous solid plastics as well as…
