Metalų ir lydinių korozija. Atmosferų koroziškumas. Aplinkos parametrų, veikiančių atmosferų koroziškumą, matavimas (ISO/DIS 9225:2026)

ISO 9225:2012 specifies methods for measuring the parameters needed for corrosivity estimation used for classification of the corrosivity of atmospheres in ISO 9223. ISO 9225:2012 specifies methods for the measurement of environmental parameters for normative corrosivity estimation based on calculated first-year corrosion rates of standard metals, and informative corrosivity estimation based on characterization of the exposure environment. It does not describe the usual analytical techniques for the measured parameters since this depends on the available analytical techniques used in laboratories. Specific methods for deposition measurement of SO2 and Cl- deposition rates and conversional factors for comparison of different measuring methods are given.

This document specifies a method for instrumental analysis by equilibration-isotope ratio mass spectrometry (Eq-IRMS) of liquid, aqueous food matrices to determine ¹⁸O/16O isotope ratios of the water of the product. The ¹⁸O/¹⁶O isotope ratios obtained by following this document are expressed as δ¹⁸O values relative to internationally recognised reference materials. This document does not apply to sample preparation. It is assumed that the food sample has been pre-treated as necessary and homogenised. Similarly, the interpretation of the obtained δ¹⁸O values is not covered by this document. Following this protocol will result only in isotope delta values for the sample materials. Although other instrumental techniques can be applied to determine δ¹⁸O values in liquid, aqueous food materials, these other techniques are not covered by this document.

Bitumas ir bituminiai rišikliai. Kompleksinio šlyties modulio ir fazės kampo nustatymas. Dinaminis šlyties reometras (DSR)

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
