Both types of testing involve testing for shorts, disconnections, miswires, and surplus circuits.<\/p>\r\n<\/div>\r\n<hr class=\"c-hr\" \/>\r\n<div class=\"c-spacer--s\">\r\n<p>In general, the judgment of continuity of cables and wire harnesses is conducted in accordance with the item \"4.5 Continuity\" of JIS-C3005 \"Testing Methods for Rubber and Plastic Insulated Wires\".<\/p><\/Br>\r\n<p class=\"c-textBig\">\"Apply a current to the conductor with a power source of 50 V or less and check the disconnection by a bell, buzzer, or other means.\"<\/p><\/Br>\r\n<p>Only the voltage of 50V or less is defined as an electrical specification.\r\nResistance and current values to determine continuity are not specified.<\/Br>\r\nThe test methods for cables and wire harnesses are based on these and expanded to digital and analog circuits.<\/p><\/Br>\r\n<p>Resistance of conductors is specified in JIS-C3005, \"4.4 Conductor Resistance.In the case of following it, the conductor resistance of the wire is tested by converting it to 1 km at 20\u00b0C (68\u00b0F).<\/Br>\r\nIt is not practical to apply this rule to mass production testing at cable and wire harness manufacturing.<\/Br>\r\nThis is because cables and wire harnesses often have different lengths of wires used in a single product and contain multiple types of wires.<\/Br><\/Br>\r\nIt is also complicated how to subtract conductor resistance from testing jigs, and how to evaluate connector contact resistance.<\/Br>\r\n<p>Cable and wire harnesses are manufactured with wires and connectors guaranteed by their manufacturers. Therefore, there are cases where testing is applied for the purpose of testing the processed parts.<\/p>\r\n<\/Br>\r\n<\/Br>\r\n<p style=\"text-align: right\">Conductor resistance is tested\/measured according to the client's requirements.\r\n<JIS C 3005 \"Testing Methods for Rubber and Plastic Insulated Wires><\/p>\r\n<\/hr>\r\n<\/div>\r\n<a class=\"c-btn c-btn--l\" href=\"en\/inspection\/wiring-test\">Click here for cable harness testers for wiring testing<\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n","protected":false},"author":1,"featured_media":3067,"menu_order":10,"template":"","meta":[],"electrical-knowledge-cat":[127],"electrical-knowledge-tag":[128],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3066"}],"collection":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge"}],"about":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/types\/electrical-knowledge"}],"author":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge\/3066\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media\/3067"}],"wp:attachment":[{"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/media?parent=3066"}],"wp:term":[{"taxonomy":"electrical-knowledge-cat","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-cat?post=3066"},{"taxonomy":"electrical-knowledge-tag","embeddable":true,"href":"https:\/\/www.naccorporation.com\/en\/wp-json\/wp\/v2\/electrical-knowledge-tag?post=3066"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
