365 Abstract: Written standards give guidance and requirements how to obtain and maintain maximum quality for product characterization. Their general purpose is to support international trade. Some standards deal with general aspects regarding the quality of measurement, in the field of particle characterization e.g., sampling, powder dispersion, data representation, and nomenclature. In other standards, a spe- cific (instrumental) method is described together with means to make the best use of it. In again others, the subject is the characterization of a specific product or group of products. All standards combine the knowledge and experience of experts coming from academia and both manufacturers and users of instruments and prod- ucts in the given field. Thus, they promote optimum application of techniques and methods for best characterization of products. Clearly, written standards are basic to consistent products. Some examples are given of both national and international standards. The reader is advised to search for relevant documents on the web sites of the standards organizations.

366 15 Written Standards 15.1 Introduction Trade of products requires adequate guarantees that the product has a defined qual- ity. For maintaining maximum quality control in production or characterization, general standards on quality management have been written. ISO (worldwide), EN (European Union) and ASTM (USA) documents support international trade. They describe the general requirements for quality assurance and management, execution of audits and terminology. For precise measurements of any parameter for a given product, specific docu- ments describing the full details of the operation procedure are required. For, only then it is guaranteed that exactly the same procedure is followed, even if differ- ent operators perform the measurements at different locations in the same type of instrument. And only then results can be obtained at a stated precision, i.e., within a given confidence interval. The documents should result from careful investigation on the critical aspects in the procedure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
