Metric standards for worldwide manufacturing 2012 electronic (8th ed.)

Аннотация

There is an old and wise saying, “No standards-no trade.” This is certainly true for standard quantities and units. Without consensus on these, trade, from shopping at the supermarket to exporting goods worldwide, would be very haphazard affair indeed. Most industrialized countries have long recognized the necessity, and advantage, of adopting the metric system of measurement-or to give it its official title, the International System of Units (SI, for short-derived from its French title, Système international d’unités), which ISO (the International Organization for Standardization) is responsible for maintaining. The SI is contained in the International Standard ISO 31, Quantities and Units, which consist of 14 separate parts. It is not only an important standard in itself, but it also serves as a basis and guideline for many other International Standards, ISO 31 is the work of ISO Technical Committee ISO/TC 12, Quantities, Units, Symbols, Conversion Factors, which has also produced the accompanying standard, ISO 1000, SI Units and Recommendations for the Use of Their Multiples and of Certain Other Units.
