Piping graphic symbol standards: JISB0125-1: 2007/ISO1219: 2006 Electrical graphic symbol standards: JISC0617: 2011/IEC60617 Therefore, the graphic symbols in the catalogs were also revised. 1. About graphic symbols stated in catalogs Take care as old graphic symbols are still included in some catalogs. Electronic catalogs at SMC website will be revised one by one. For further information, please refer to SMC website (http://www.smcworld.com). The following describes the contrasting examples between new and old symbols. 2. About port indication The port symbol was changed from the alphabetic indication to the numeric indication. Take care as the indication stated in the catalog may differ from that on the actual product. The following describes indication examples. Example) Air cylinder Solenoid valve New ISO Old ISO New ISO Old ISO Example) Catalog indication Product indication 1. The thread shape (root diameter, thread diameter, and pitch, etc.) and gauge diameter of the G thread conform to the thread standards defined in JIS B0202 (ISO228-1). 2. The products with the ISO1179-1 (hydraulic/pneumatic G thread) or ISO16030 (pneumatic G thread) indications conform to the thread shape and gauge diameter standards JIS B0202 (ISO228-1), and relevant effective thread depth, seat surface range, surface roughness, and squareness standards. 3. As for ISO1179-1 (hydraulic/pneumatic G thread), original pressure tightness (withstand pressure) values are specified for each SMC product. These pressure tightness (withstand pressure) values do not guarantee those defined in ISO 1179-1, ISO1179-2, ISO1179-3, and ISO1179-4. 4. As for ISO16030 (pneumatic G thread), original pressure tightness (withstand pressure) values are specified for each SMC product. These pressure tightness (withstand pressure) values do not guarantee those defined in ISO16030. Information on Symbol Revision G Thread of SMC Products 72
