Hydraulic Training by J. Eric Freimuth Hydraulic Training Associates Know the ISO Symbols that Relate to Components What does ISO stand for? Many believe it is the International Standards Organization or something of that fash- ion. The organization, which today is known as ISO, began in 1926 as the International Federation of the National Standardizing Associations (ISA). This organization focused heavily on mechan- ical engineering. It was disbanded in 1942 during the second World War, but was reorganized under the current name ISO, in 1946. Even the name of the organization is standardized. The name “ISO” is not an acronym, it was derived from the Greek “isos” meaning “equal”. (The relation to standards is, if two objects meet the same standard, they should be equal.) This name eliminates the confusion that could result from the translation of “International Organization for Standardization” into different lan- guages which could lead to different acronyms. “ABrief History of ISO” can be found at: www.sis.pitt.edu /~mbsclass/ standards/martincic/isohistr.htm Symbols are critical for technical communication. They are not dependent on any specific language, being interna- tional in scope and character. Hydraulic graphic symbols emphasize the function and methods of operation of the com- ponents. These symbols can be rather simple to draw, if the logic and elemen- tary forms used in symbol design are understood. The elementary forms of symbols are circles, squares, triangles, arcs, arrows, dots, and crosses. Each symbol holds a specific func- tion for the component it is describing. To learn the symbols is like learning another language; also like learning a language, if not used, it will be a struggle to remember. Encourage your mechan- ics to read and become familiar with the ISO symbols and reading a schemat- ic will become like a second language to them. No mechanic has x-ray eyes, so see- ing what the systems components are without a schematic is near impossible to troubleshoot. Many mills and indus- trial plants have stationary units which mechanics become familiar with, but even then there are components they sometimes forget about. A schematic will assist in the identification of these com- ponents and is the best tool a mechanic has to provide answers to a situation or breakdown. In my classes, I instruct all all elec- tricians place their schematics right in the control panel of the electrical boxes. So why don’t we have our hydraulic or pneumatic schematics located next to the units as well? Instead, more often than not, they are placed in a book in the office or nowhere to be found. I encourage the mechanics to take their schematics copies, place them in a plas- tic envelope, and attach them to the equipment. This way they can always be available when needed. Just recently, I supplied a wind farm with their schematic animated and in MP4 format. This allowed them to put the schematics on the mechanics’ smart- phones. When they went 40 feet up in the towers, they had the schematics and they were animated. This allowed them to see the components move as the valves were shifted. A great trou- bleshooting tool.
