Unplasticized polyamide (PA-U) pipes — Effect of time and temperature on the expected strength
This International Standard specifies the minimum values for expected strength as a function of time
and temperature in the form of reference lines, for use in calculations on pipes made of: - unplasticized
Polyamide (PA-U 180). Note: PA-U 180 follows ISO 16486-1 and covers both PA-U11 180 and PA-U12 180
Microbeam analysis — Analytical electron microscopy — Selected area electron diffraction analysis us...
ISO 25498:2018 specifies the method of selected area electron diffraction (SAED) analysis using a transmission electron microscope (TEM) to analyse thin crystalline specimens. This document applies to test areas of micrometres and sub-micrometres in size. The minimum diameter of the selected area in a specimen which can be analysed by this method is restricted by the spherical aberration…
Compliance management systems — Guidance for competence management
This document provides guidelines for the competence management and personnel development of compliance management in an organization to positively influence outcomes related to the effectiveness of compliance management system and the needs and expectations of relevant stakeholders.
This document is applicable to compliance management competence management and personnel development in all…
Rubber — Measurement of vulcanization characteristics using curemeters — Part 2: Oscillating disc cu...
This document specifies a method for determining selected vulcanization characteristics of a rubber compound by means of an oscillating disc curemeter. The introduction to the use of curemeters is described in ISO 6502‑1.
Coal and coke — Mechanical sampling — Part 7: Methods for determining the precision of sampling, sam...
In ISO 13909-7:2016, formulae are developed which link the variables that contribute to overall sampling precision. Methods are described 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.
Coal and coke — Mechanical sampling — Part 3: Sampling of coal from stationary lots
ISO 13909-3:2016 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 13909‑2:2016. Procedures for sample preparation are given in ISO 13909‑4:2016.
ISO 13909-3:2016 is applicable to mechanical…
Coal and coke — Mechanical sampling — Part 2: Sampling of coal from moving streams
ISO 13909-2:1016 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[1].
Coal and coke — Mechanical sampling — Part 1: General introduction
ISO 13909-1:2016 defines the basic terms used in the sampling of solid mineral fuels, 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 and gives guidance on the selection of the appropriate part.
It does not include sampling of brown coals and lignites, or sampling from coal seams,…
ISO 21207:2015 defines two accelerated corrosion test methods to be used in assessing the corrosion resistance of products with metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or by winter road de-icing salt, and of corrosion-promoting gases from industrial or traffic air pollution.
ISO 21207:2015 specifies both the…
Coal and coke — Mechanical sampling — Part 5: Sampling of coke from moving streams
ISO 13909-5:2016 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…
