BS ISO 11277 specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction.
BS ISO 11277 has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required.
A major objective of BS ISO 11277 is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution curve.
BS ISO 11277 does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It is also realized that the chemical pretreatments and mechanical handling stages in BS ISO 11277 could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then BS ISO 11277 is not used for the determination of the particle size distribution of such weakly cohesive materials.

Experimental Techniques in Materials and Mechanics provides a detailed yet easy-to-follow treatment of various techniques useful for characterizing the structure and mechanical properties of materials. With an emphasis on techniques most commonly used in laboratories, the book enables students to understand practical aspects of the methods and derive the maximum possible information from the experimental results obtained.
The text focuses on crystal structure determination, optical and scanning electron microscopy, phase diagrams and heat treatment, and different types of mechanical testing methods. Each chapter follows a similar format:
Discusses the importance of each technique
Presents the necessary theoretical and background details
Clarifies concepts with numerous worked-out examples
Provides a detailed description of the experiment to be conducted and how the data could be tabulated and interpreted
Includes a large number of illustrations, figures, and micrographs
Contains a wealth of exercises and references for further reading
Bridging the gap between lecture and lab, this text gives students hands-on experience using mechanical engineering and materials science/engineering techniques for determining the structure and properties of materials. After completing the book, students will be able to confidently perform experiments in the lab and extract valuable data from the experimental results.
