United States and International Color Coding
Standard ASTM E 230 color coding (United States) is used on all insulated thermocouple wire and extension wire when type of insulation permits. In color coding, the right is reserved to include a tracer to identify the ASTM E 230 type. Thermocouple grade wire normally has a brown overall jacket. For Types B, R and S the color codes relate to the compensating cable normally used. Various national and international standard agencies have adopted color codes for the identification of thermocouple products. These generally differ from those specified in ASTM E 230. Additionally, the overall extension color code is used to identify connectors to specific thermocouple types.
