ISO 17668:2016 specifies minimum thickness requirements for six classes of zinc diffusion layers applied to ferrous products by the sherardizing process for the purpose of protection against corrosion and wear. ISO 17668:2016 does not specify any requirements for the surface condition (finish or roughness) of the basis material before sherardizing. Post-treatments (conversion coatings), after-…

ISO 8513:2016 specifies two test methods for determining the longitudinal tensile properties of glass-reinforced thermosetting plastics (GRP) pipes. The properties which can be determined are - the longitudinal tensile strength, and - the percentage ultimate elongation. Method A uses, for the test piece(s), a longitudinal strip cut from a pipe. Method B uses a specified length of the…

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/TS 17307:2016 establishes a method for determining the total methyl ester content in fatty acid methyl ester (FAME) by gas chromatography and using an external standard. The method is suitable for biodiesel which contains esters between C6 and C26. This method allows verifying that the total ester content is greater than 96,5 % (m/m). NOTE 1 The method also allows determination of the…

ISO 7503 (all parts) and ISO 8769 are addressed to the people responsible for determining the radioactivity present on solid surfaces. ISO 7503 is published in three parts and can be used jointly or separately according to needs. ISO 7503-1:2016 relates to the assessment of surface contamination by direct and indirect measurements and the calibration of the associated instrumentation. The…

ISO 19905-1:2016 specifies requirements and guidance for the site-specific assessment of independent leg jack‑up units for use in the petroleum and natural gas industries. It addresses: manned non-evacuated, manned evacuated and unmanned jack‑ups; the installed phase at a specific site. To ensure acceptable reliability, the provisions of this part of ISO 19905 form an integrated…

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…

ISO 4628-3:2016 specifies a method for assessing the degree of rusting of coatings by comparison with pictorial standards. The pictorial standards provided in this part of ISO 4628 show coated steel surfaces which have deteriorated to different degrees by a combination of rust broken through the coating and visible underrust. NOTE 1 The pictorial standards have been selected from the "…

ISO 8769:2016 specifies the characteristics of reference sources of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This International Standard relates to alpha-emitters, beta-emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV. It does not describe the procedures involved in the use…
