ISO 6974-6:2002 describes a gas chromatographic method for the quantitative determination of the content of helium, hydrogen, oxygen, nitrogen, carbon dioxide and C1 to C8 hydrocarbons in natural gas samples using three capillary columns. This method is applicable to the determination of these gases within the mole fraction ranges varying from 0,000 1 % to 40 %, depending on the component…

Applies to hand-held and hand-manipulated CURRENT CLAMPS. These CURRENT CLAMPS are for use in the measurement of current without interruption of the current path of the circuit in which it is measured. They may be stand-alone CURRENT CLAMPS which are themselves within the scope of part 1, or accessories to other equipment within the scope of part 1. This standard does not apply to current…

ISO 12710 describes a set of procedures for the measurement of any performances in an ultrasonic test instrument that has a display screen. This International Standard establishes the procedures for measuring performance characteristics of components of pulse-echo ultrasonic non-destructive testing instruments including both analog and digital type instruments with screen displays. The aim is to…

The purpose of this International Standard is to achieve a high degree of harmonization in reporting results of on-site recording, sampling, on-site sample analyses and laboratory analyses of soil samples. To this end, it provides instructions for correctly specifying the quantities and units used to express results of analyses, the methods used and their precision. This International Standard…

ISO 4142:2002 specifies a range of test tubes, suitable for general laboratory use, fabricated from borosilicate, neutral or soda/lime glass, which are designated Type I, Type II and Type III respectively.

This International Standard specifies, for the field of air quality measurement procedures, the: estimation of measurement uncertainty from actual or claimed values of all important performance characteristics of a method under stationary conditions; assessment of whether or not specified values for these performance characteristics comply with the required quality of a measured value at a…
