The Celsius temperature relative to the temperature index is not the recommended enameled wire use temperature because the temperature of use is related to many factors, including the type of equipment involved.

package

The type of packaging may affect certain properties of the enameled wire, such as resilience. Therefore, the type of packaging (such as the type of delivery reel) should be determined by both the supplier and the buyer.
The enameled wire should be wound evenly and tightly on the delivery reel or placed in the container. Unless there is agreement between the supplier and the buyer, there should be no more than one line of enameled wire in the delivery reel or container. When there is more than one line segment, the length of the line segment shall be indicated on the label and/or on the package by negotiation between the supplier and the buyer.
When the enameled wire is delivered in a loop, the size and maximum quality of the loop shall be determined by negotiation between the supplier and the buyer. Any additional protection on the coil shall also be determined by negotiation between the supplier and the purchaser.
The label shall be hung on each packaging unit agreed upon by the supplier and the buyer and shall include the following:
1. Manufacturer's name and/or trademark; 2. Enamelled wire and paint film type, such as product name and/or national standard number; 3. Enameled wire net weight; 4. Enameled wire nominal diameter and paint film level; 5. Date of manufacture.
