ISO/TR 15403-2:2006 addresses the specifications of natural gas as a compressed fuel for vehicles as an addendum to ISO 15403-1. Specifically, ISO/TR 15403-2:2006 is intended to satisfy requests for quantitative data. The critical items regarding gas composition are water content, sulfur compounds, particulate matter, higher hydrocarbons, CO2, free oxygen, glycol/methanol, oil content and…

This Technical Report is intended as an aid for understanding the libraries specified in Standard ECMA-335, Partition IV: Profiles and Libraries. That Partition includes a machine-readable specification, in XML, of the types that comprise the standard libraries. This Technical Report, in companion files, provides the following items which help to form a traceable chain from the normative XML…

ISO 18369-4:2006 specifies the methods of testing the physicochemical properties of contact lens materials. These are extraction, rigid lens flexure and breakage, oxygen permeability, refractive index and water content.

Specifies a method to measure the conducted electromagnetic emission (EME) of integrated circuits by direct radio frequency (RF) current measurement with a 1 Ω resistive probe and RF voltage measurement using a 150 Ω coupling network. These methods guarantee a high degree of repeatability and correlation of EME measurements. IEC 61967-1 specifies general conditions and definitions of the test…

ISO 15860:2006 covers gases (air, nitrogen, helium, and argon) compressed up to 40 MPa used in systems and units of space vehicle launch and technical complexes. ISO 15860:2006 determines compressed gas impurities (mechanical impurities, water vapour, oil, and foreign gases) content measurement methods. It can be used by countries and firms participating in the development, redesign,…

Specifies the construction and testing of intrinsically safe apparatus intended for use in an explosive gas atmosphere and for associated apparatus, which is intended for connection to intrinsically safe circuits which enter such atmospheres. The contents of the corrigendum of December 2006 and interpretation sheet 1 of December 2019 have been included in this copy.

Describes the effects of unbalanced voltages on the performance of three-phase cage induction motors. The contents of the corrigendum of September 2014 have been included in this copy.

ISO 18933:2006 concerns the care and handling of magnetic recording tape during use. It addresses the issues of physical integrity of the medium necessary to preserve access to the data (information) recorded on the tape. ISO 18933:2006 recommends handling procedures to maximize the effective life of magnetic tape. While some of the recommendations in ISO 18933:2006, such as staff training, apply…

This part of IEC 61755 defines certain dimensional limits of a 2,5 mm and a 1,25 mm diameter cylindrical zirconia (ZrO2) PC ferrule optical interface to meet specific requirements for fibre-to-fibre interconnection. Ferrules made from the material specified in this document are suitable for use in categories C, U, E, and O as defined in IEC 61753-1. The contents of the corrigendum of January 2009…
