Interpretation Request #1 Clause 5.4 requires the “immersed test specimens, will be heated for the specified

5、time and temperature (refer to Table 1).” For Type 2, Semiconducting materials, Table 1 calls for immersion at 121 degrees Celsius for 168 hours. A water-based lubricant such as mine will vaporize and dissipate in that time period, therefore the test Page 1 of 2IEEE Std 1210-20048/6/2010http:/standa

6、rds.ieee.org/reading/ieee/interp/1210-2004.htmlspecimen cannot remain “immersed.” Is the intention to immerse the specimen, expose it to lubricant until such time as the liquid evaporates, then continue exposing it to the remaining residue for the remaining time period? Interpretation Response #1 Ta

7、ble 1 contains a number of aging temperatures at or above the boiling point of water. These are the “typical” short-term accelerated aging temperatures for these jackets as found in multiple specifications.Since most pulling lubricants are water-based, some dissipation of the water is anticipated. H

8、ow much depends on the time and temperature. However, a quantity of 350 ml and a low volume vapor escape situation (5 mm hole in rubber stopper) is specified in the test. A reflux environment is established at all temperatures and often there is still water present at the end of the aging. Note the

9、same issue when a “water” control is used for cable jackets approved for a wet environment. Regardless, set up the test as specified (specified temperature, specified lubricant quantity, and specified vapor escape (to avoid a pressurized environment). Run the aging for the full specified time length
