This standard specifies the procedure to determine the relation between the water content and the dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a 2.495 kg rammer dropped from a height of 305 mm. Three methods are used to determine this relation (see Chapter 5). NOTE — The laboratory compaction test methods described in this standard generally…

This standard specifies a procedure to determine the relation between the water content and the dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a 4.536 kg rammer dropped from a height of 457 mm. Three methods are used to determine this relation (see Chapter 5). NOTE — The laboratory compaction test methods described in this standard generally provide…

IEC 61010-031:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61010-031:2022 edition 3.0 and the previous IEC 61010-031:2015+AMD1:2018 CSV edition 2.1. Furthermore, comments from IEC TC 66 experts are provided to explain the reasons of the most relevant changes, or to…

IEC 61010-031:2022 specifies safety requirements for hand-held and hand-manipulated probe assemblies for electrical test and measurement, and their related accessories. These probe assemblies are for non-contact or direct electrical connection between a part and electrical test and measurement equipment. They can be fixed to the equipment or be detachable accessories for the equipment. It has…

This document provides guidance for —    the sampling process of the aerosol particles in the air using filter media. This document takes into account the specific behaviour of aerosol particles in ambient air (Annex B). —    Two methods for sampling procedures with subsequent or simultaneous measurement: —    the determination of the activity concentration of radionuclides bound to aerosol…

This document specifies the general requirements, based on ISO 11074 and ISO/IEC 17025, for all steps in the planning (desk study and area reconnaissance) of the sampling and the preparation of samples for testing. It includes the selection of the sampling strategy, the outline of the sampling plan, the presentation of general sampling methods and equipment, as well as the methodology of the pre-…

This document specifies two procedures for the preparation of laboratory sheets prior to measuring optical properties. One is the preparation of pads in a Büchner funnel using a filter paper or a wire screen and the other one is the preparation of laboratory sheets in a standard sheet former (conventional or Rapid Köthen). This document is applicable to all wood pulps and to most other types of…

This document specifies a test method for preparation of test prints produced with liquid printing inks, either water-based, solvent-based or radiation cured printing inks as used in flexography and gravure printing. Such test prints are intended to be used for reflection-based measurements, such as colorimetry and optical density as well as for testing light fastness, and the resistance of…

1 Scope 1.1 General There is a commentary available for this Clause. This fenestration Standard/Specification applies to both operating and fixed, new construction and replacement windows, doors, SSPs, TDDs, roof windows, and unit skylights. This fenestration Standard/ Specification is material-neutral and establishes performance requirements for windows, doors, SSPs, TDDs, roof windows,…

This document specifies experimental procedures and statistical analysis for the determination of measurement uncertainty in situations where the following conditions are fulfilled: Condition 1: The level of the measurand is non-negative, e.g. concentration level of a contaminant in a sample. Condition 2: Measurement error consists of two independent components: for one of these components the…
