This document specifies a method for measurement of the viscosity of a ceramic slurry using a rotational viscometer. The method only involves rotations with a monotonic angle variation. Measurements using an oscillating rotation are excluded from the scope of this document. Ceramic slurry is used in ceramic processes such as dip coating, spray coating, screen printing, slip casting, tape casting, spray drying and polishing. Dispersion of fillers in molten thermoplastic polymers are excluded from the scope of this document.

 

This document specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low-energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) are not be included in the gross beta quantification using the test method described in this document. This test method is applicable to the analysis of raw and drinking waters with low amounts of total soluble salts in the water. Limit of detection depends on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested. As this method requires sample preparation in laboratory facilities, it is not suited for rapid, in-the-field analysis.

 

This part of ISO 27327 establishes uniform methods for laboratory testing of air curtain units to determine aerodynamic performance in terms of airflow rate, outlet air velocity uniformity, power consumption and air velocity projection, for rating or guarantee purposes. This part of ISO 27327 is not applicable to the specification of test procedures to be used for design, production or field testing.
