ISO/TR 15599:2002 provides a code of dental laboratory procedures which is digital so as to render it language-independent. This makes it convenient to use as a basic reference for existing or future dental codes, and ensures their compatibility through simple softwares, which is the fundamental goal of the exercise. In addition the digital code is intended to provide, as a result of built-in…

This document specifies requirements for multispectral imaging devices to measure and compare the decorative surfaces. Based on spatially resolved spectral measurement of reflecting surfaces, tristimulus images are computed. A metric is provided that reflects the visual closeness between a reference surface and a comparison surface using a single index called SIM_PDE. Recommendations are provided…

Adopts both the veiling glare index (VGI) and the glare spread function (GSF) as measures of the veiling glare characteristics of optical and electrooptical imaging systems. Laboratory measurement techniques are described in general terms and recommendations are made regarding the performance of the main subunits of the equipment. The measurement techniques described are chiefly valid for the…

1. PURPOSE AND SCOPE 1.1 This method is intended to indicate the response of the fibre to a standardized mechanical treatment, as an index of its papermaking quality. 1.2 This method may be used to define the papermaking quality of pulp by subjecting it to treatment in a standardized laboratory beater according to a definite schedule. 1.3 This method…

IEC TR 60216-7-2:2016(E), which is a Technical Report, is to validate the procedures of IEC TS 60216-7-1 in providing a similar temperature index to conventional methods used in other parts of the IEC 60216 series. These round robin test results do not provide statistical analysis for precisions. The round robin test focuses on preliminary studies to understand the evaluation and calculation…

ISO/TS 17892-6:2004 specifies the laboratory determination of undrained shear strength of both undisturbed and remoulded specimen of saturated fine grained cohesive soils by use of a fall-cone. This document specifies the fall-cone test, in which a cone is allowed to fall with its tip towards a soil specimen, whereupon the penetration of the cone into the soil is measured. Tests performed…

Four methods are described for measuring chromatic dispersion: (a) phase shift, (b) spectral group delay in the time domain, (c) differential phase shift, and (d) interferometry. Methods (a), (b) and (c) apply to class A1 graded-index multimode fibres and class B single-mode fibres. Method (d) applies to single-mode fibres, class B1 to B3 in the 1000 nm to 1700 nm wavelength range. The methods…

ISO 15186-2:2003 specifies a sound intensity method to determine the in-situ sound insulation of walls, floors, doors, windows and small building elements. It is intended for measurements that have to be made in the presence of flanking transmission. It can be used to provide sound power data for diagnostic analysis of flanking transmission or to measure flanking sound insulation parameters. ISO…

Describes methods for a test which simulates the acoustical effects of a median adult wearer on the performance of a hearing aid. Establishes certain guidelines for simulated in situ measurements of hearing aids; it describes a simplified method for simulated in situ measurements of hearing aids and a description for determination of the directivity index (DI) of directional microphones in…

IEC 60477-2:2022 applies to resistors intended as laboratory AC resistors for use over a range of frequencies from DC up to a stated frequency which is not in excess of 1 MHz. Such resistors are hereinafter referred to as "AC resistors". In addition to satisfying the requirements of IEC 60477-1, resistors satisfying the requirements of this document are designed to have a small…
