5.1.9 Bend test on nylon-covered conductors
A nylon covering over an individual insulated conductor (see Clause 4.1.3.4) or on a SPT-1 cord (see
Clause 4.3.10.4) shall not show any cracks when wound six complete close turns around a mandrel
having the same diameter as the fifinished conductor (the minor diameter in the case of a SPT-1 cord) after
specimens have been subjected to the air-oven aging test applicable to the insulation class. Following the
air-oven test, the specimen shall be allowed to cool for 16 h to 96 h prior to flflexing. Wrinkles or folds in
the nylon do not constitute failures.
这很好理解。after specimens have been subjected to the air-oven aging test applicable to the insulation class试样经过适用于绝缘等级的空气烘箱老化试验后。 即是按绝缘的老化条件。
