This document specifies a test method to measure the ultraviolet (UV) and visible (VIS) spectral transmittance in the wavelength range from 280 nm to 700 nm of coatings for wind turbine rotor blades. Single and multilayer coatings or coating systems can be tested. From the spectral transmittance the transmittance of UV, VIS and the combined UV and VIS wavelength range can be calculated. It is…

This document specifies the cooling efficiency ratio (CER) as a key performance indicator (KPI) for quantifying the efficient use of energy to control the temperature of spaces within a data centre (DC). This document: a)    defines the CER of a DC; b)    describes the relationship of this KPI to a DC’s infrastructure, information technology equipment and information technology operations; c)   …

This document describes a procedure for determining the content of residual alkali in Kraft black liquors having a dry matter content up to 40 %. The method is based on a potentiometric titration with hydrochloric acid and is intended for black liquor samples with an initial pH ≥ 11,0. The lower limit of determination is 0,1 g/l of eq. NaOH.

This document specifies a potentiometric titration procedure for the determination of total, active and effective alkali in white and green liquors obtained and used in the kraft or sulphate pulping process. This document is not applicable for the analysis of liquors such as oxidized white liquors which contain significant amounts of polysulphides. The method given in this document is not…

This document describes a procedure for the determination of sulphide, i.e. the hydrosulphide ion concentration, in white, oxidized white and green liquors, as well as in black liquor having a dry matter content up to 40 %. The determination also includes the sulphide part of any polysulphide present in the solution.

This document specifies test method to determine the resistance to wind load of completely assembled windows and pedestrian door sets of any materials when exposed to positive or negative test pressures. This test method is designed to take account of conditions in use, when the window or door set is installed in accordance with the manufacture's specification and the requirements of…
