Claim 10:
11. A method for monitoring cumulative heat exposure to a pre-expanded elastomeric cable accessory unit for covering an electrical cable or cable connection, the method comprising:
providing an electrical cable accessory system including:
a pre-expanded cable accessory unit including:
a pre-expanded cable accessory formed of an elastomeric material; and
a removable holdout mounted within the elastomeric cable accessory, wherein the holdout is operative to maintain the elastomeric cable accessory in an expanded state and to permit the elastomeric cable accessory to elastically contract when the holdout is removed from the elastomeric cable accessory; and
a time-temperature indicator associated with the pre-expanded cable accessory unit, wherein the time-temperature indicator is configured to undergo a visible change in appearance in response to a cumulative heat exposure; and

monitoring the visible change in appearance of the time-temperature indicator to determine whether the elastomeric material of the pre-expanded elastomeric cable accessory unit has experienced a threshold cumulative heat exposure,
wherein the threshold cumulative heat exposure for the pre-expanded cable accessory unit is about 60° C. (140° F.) over a time period of about 60 days.
