This document defines a reference comparison method. This method is applicable to two or more character strings to determine their collating order in a sorted list. The method can be applied to strings containing characters from the full repertoire of ISO/IEC 10646. This method is also applicable to subsets of that repertoire to produce ordering results valid (after tailoring) for a given set of…

Le présent document définit une méthode de comparaison de référence. Cette méthode est applicable à deux chaînes de caractères ou plus pour déterminer leur ordre de classement dans une liste triée. La méthode peut être appliquée aux chaînes contenant des caractères du répertoire complet de l'ISO/IEC 10646. Cette méthode est également applicable aux sous-ensembles de ce répertoire pour…

This document defines methods for estimating overall precision and for deriving values for primary increment variance which can be used to modify the sampling scheme to change the precision. Methods for checking the variance of sample preparation and testing are also described. In this document, formulae are developed which link the variables that contribute to overall sampling precision.

This document specifies procedures for the mechanical sampling of coal from stationary lots, for example, from wagons, barges, ships and stockpiles. These procedures are to be used when it is not possible to sample the lots during loading or discharge according to ISO 13909-2. Procedures for sample preparation are given in ISO 13909-4. This document is applicable to mechanical sampling from…

This document specifies procedures and requirements for the design and establishment of mechanical samplers for the sampling of coal from moving streams and describes the methods of sampling used. It does not cover mechanical sampling from stationary lots, which is dealt with in ISO 13909-3.

This document defines the basic terms used in the sampling of coal and coke, describes the general principles of sampling and details the information to be provided in the documentation and the sampling report. It also lists the other parts of the ISO 13909 series and gives guidance on the selection of the appropriate part. The ISO 13909 series also includes sampling of brown coals and lignites.

This document specifies procedures and requirements for the design and establishment of sampling schemes for the mechanical sampling of coke from moving streams and the methods of sampling used. The diversity of types of equipment for sampling and the conditions under which mechanical sampling is performed make it inappropriate to specify standard designs for samplers which will be applicable to…

This document specifies the procedures to be followed when connecting cylinder valves to gas cylinders. It specifically applies to all valve and cylinder combinations connected with ISO screw threads as specified in ISO 11363-1 and ISO 15245-1. It defines procedures and practices for inspection and preparation prior to valving for both taper and parallel screw threads. Torque values are given in…

This document describes the preparation of samples of coal from the combination of primary increments to the preparation of samples for specific tests.

This document describes the preparation of samples of coke from the combination of primary increments to the preparation of samples for specific tests.
