ISO 18385:2016 specifies requirements for the production of products used in the collection, storage, and analysis of biological material for forensic DNA purposes, but not those consumables and reagents used in post-amplification analysis. The consumables and reagents covered by this International Standard include those used for evidence collection (sampling kits), such as swabs, containers, and…

ISO/TS 19022:2016 specifies a test method which allows predicting the aging rate of material specimens, e.g. plastics, under interest independent of the aging mechanisms as a function of radiant exposure. The UV irradiance of a simulated solar radiation (with a laboratory radiation source) will be extended above the normal maximum level on earth surface while keeping all relevant temperature…

ISO 7503 and ISO 8769 are addressed to the people responsible for determining the radioactivity present on solid surfaces. ISO 7503-3:2016 applies to the evaluation of contamination on surfaces in terms of activity per unit area by direct and indirect methods of measurement and deals with the complex aspects of instrument calibration. ISO 7503-3:2016 is applicable to well-defined surfaces, such…

ISO 7503 (all parts) and ISO 8769 are addressed to the people responsible for measuring the radioactivity present on solid surfaces. ISO 7503-2:2016 applies to the evaluation of contamination on surfaces in terms of activity per unit area by an indirect method of measurement. ISO 7503-2:2016 is applicable to well-defined surfaces, such as those of equipment and facilities, containers of…

ISO 16496:2016 recommends dimensions and specifies requirements and test methods for laboratory glassware manufactured from borosilicate glass 3.3 and provided with a vacuum jacket for thermal insulation. It covers Dewar vessels, vacuum-jacketed reaction vessels and vacuum-jacketed columns intended for laboratory use and laboratory related applications. Typical dimensions are given in Tables 1 to…

ISO 15912:2016 gives requirements and test methods for determining the compliance of dental casting investment, dental brazing investment, dental pressable-ceramic investment and dental refractory die materials used in the dental laboratory, regardless of the composition of the refractory powder, the composition of the binder, or the particular application. ISO 15912:2016 classifies such products…

ISO 6926:2016 specifies the acoustical performance requirements for reference sound sources: - temporal steadiness (stability) of the sound power output; - spectral characteristics; - directivity. Temporal steadiness is defined in terms of the standard deviation of repeatability (see 5.2). The spectral characteristics can be verified in either a hemi-anechoic room or a…
