1. SCOPE 1.1 This method is intended for the semi-quantitative (i.e., ±25%1) determination of ethyl mercaptan odorant (within the range of 5 to 85 mg/L) in liquid propane. It is important to confirm that recently stenched propane is odorized to the required level. The method is intended for field application and may be suitable for use by non-laboratory personnel after suitable training. A gas…

ISO/IEC 25051:2005 defines quality requirements for COTS software products. A COTS software product includes the product description, the user documentation, and the software contained on a computer sensible media. The quality requirements, functionality, reliability, usability, efficiency, maintainability, portability, and quality in use are consistent with the definitions of SQuaRE. In addition…

ISO 8178-11:2006 specifies the measurement and evaluation methods for gaseous and particulate exhaust emission from reciprocating internal combustion (RIC) engines under transient conditions on a test bed, necessary for determining one value for each exhaust gas pollutant. The specific transient test cycle covered by ISO 8178-11:2006 is applicable to compression-ignition engines for mobile use…

ISO 16312-1:2006 provides technical criteria and guidance for evaluating physical fire models (i.e. laboratory combustion devices and operating protocols) used in effluent toxicity studies for obtaining data on the effluent from products and materials under fire conditions relevant to life safety. Relevant analytical methods, calculation methods, bioassay procedures and prediction of the toxic…

ISO 10848-3:2006 applies to structurally connected light elements forming a T or X junction. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction, or as the vibration reduction index of a junction.

ISO 10848-2:2006 applies to light elements such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can be simultaneous through the test element and via the plenum, if any. With measurements according to ISO 10848-2:2006, the total sound transmission is measured, and it is not possible to separate the two kinds of…

ISO 10848-1:2006 contains definitions, general requirements for test specimens and test rooms, and methods for measurement of the flanking transmission. Guidelines are given for the selection of the quantity to be measured depending on the junction and the types of building elements involved.

determines the coupling or screening attenuation of metallic communication cables in the frequency range of 30 MHz to 1 000 MHz. It is an alternative method to the injection clamp method of IEC 62153-4-3 or the triaxial method of IEC/ PAS 62338. Due to the undefined outer circuit of this absorbing clamp method, the test results obtained at different places and laboratories could vary by at least…

ISO 15011-4:2006 covers health and safety in welding and allied processes. ISO 15011-4:2006 specifies requirements for determination of the emission rate and chemical composition of welding fume in order to prepare fume data sheets.. It applies to all filler materials used for joining or surfacing by arc welding using a manual, partly mechanised or fully automatic process, depositing unalloyed…
