Electronic displays - Part 2-7 : Measurements of optical characteristics - Tiled displays
IEC 62977-2-7:2024 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in…
Indoor air — Part 9: Determination of the emission of volatile organic compounds from samples of bui...
This document specifies a general laboratory test method for the determination of the area specific emission rate of volatile organic compounds (VOCs) from samples of newly produced building products or furnishing under defined climate conditions. The method can also, in principle, be applied to samples of aged products. The emission data obtained can be used to calculate concentrations in a…
Crude petroleum, petroleum products and related products — Determination of density — Laboratory den...
This document specifies a method for the determination, using an oscillating U-tube density meter, of the density of crude petroleum and related products within the range 600 kg/m3 to 1 100 kg/m3, which can be handled as single-phase liquids at the test temperature and pressure.
This document is applicable to liquids of any vapour pressure as long as suitable precautions are taken to ensure that…
Rubber, vulcanized or thermoplastic — Determination of stress relaxation in compression — Part 1: Te...
This document specifies two procedures for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature.
The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one.
Two test methods…
