Hydraulic fluid power — Design methodology for energy efficient systems
This document specifies a design methodology for hydraulic systems that can be operated with the lowest possible energy consumption while maintaining the intended functionality of the stationary or mobile machinery in which they are installed.
This document takes into account the duty cycles of the application. The definition of the duty cycles is not part of this standard.
This document describes a simplified routine method applicable to the dynamic or static sampling, by manual or mechanical means, of cereals, pulses and cereal products for assessment of their quality and condition. It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances and parameters usually homogenously distributed, such as those…
Coal and coke — Mechanical sampling — Part 8: Methods of testing for bias
ISO 13909-8:2016 sets out principles and procedures for testing the bias of test samples of hard coals or cokes, taken in accordance with ISO 13909: 2016 (all parts).
NOTE In the text, the term "fuel" is used where both coal and coke would be applicable in the context and either "coal" or "coke" where only one is applicable.
Water quality — Determination of the toxicity of water samples on the embryo-larval development of J...
This document specifies a method for determining the effects of chemical and aqueous samples on the embryo-larval development of marine bivalves. It allows the determination of the concentration levels that result in an abnormality in embryo-larval development. This test is suitable for salinity ranges between 20 and 40 for mussels and between 25 and 35 for oysters. This method applies to
