Plastics — Determination of haze for transparent materials
This document specifies a method for the measurement of haze, an optical property resulting from wide-angle scattering of light, in transparent and substantially colourless plastics. This method is applicable to the measurement of haze values of less than 40 %.
NOTE The haze of abraded or matted transparent plastics can be measured, but the value obtained can be erroneously lower than the…
Clinical laboratory testing and in vitro diagnostic test systems — Broth micro-dilution reference me...
This document describes a method for testing the susceptibility to antifungal agents of yeasts, including Candida spp. and Cryptococcus neoformans, that cause infections. The reference method described here has not been used in studies of the yeast forms of dimorphic fungi, such as Blastomyces dermatitidis and/or Histoplasma capsulatum variety capsulatum. Moreover, testing filamentous fungi (…

IEC TS 62607-9-1:2021(E) establishes a standardized method to characterize spatially varying magnetic fields with a spatial resolution down to 10 nm for flat magnetic specimens by magnetic force microscopy (MFM). MFM primarily detects the stray field component perpendicular to the sample surface. The resolution is achieved by the calibration of the MFM tip using magnetically nanostructured…

IEC TS 62607-6-6:2021(E) establishes a standardized method to determine the structural key control characteristic
• strain uniformity
for single-layer graphene by
• Raman spectroscopy.
The width of the 2D-peak in the Raman spectrum is analysed to calculate the strain uniformity parameter which is a figure of merit to quantify the influence of nano-scale strain variations on the electronic…

IEC TS 62607-6-10:2021(E) establishes a standardized method to determine the electrical key control characteristic
– sheet resistance (Rs)
for films of graphene-based materials by
– terahertz time domain spectroscopy (THz-TDS).
In this technique, a THz pulse is sent to the graphene-based material. The transmitted or reflected THz waveform is measured in the time domain and transformed to the…
