粘合性指数。测量瓷釉和陶瓷涂层对钣金的粘合性的度量。(ASTM C - 313)。


Alpha Rockwell hardness. Index of the resistance of a plastic to surface penetration by a specified indentor under specified load applied with a Rockwell hardness tester. Higher values indicate higher indentation hardness. (ASTM D-786).
Annealing point. Temperature at which internal stress in glass is substantially relieved in 15 min. (ASTM C-336).

洛氏A极硬度。使用洛氏硬度计测定塑料于指定负载作用下对指定压痕器表面穿透能力的抗阻指数。其中,数值越高表示压痕硬度越高。(ASTM D-786).
退火点。于15分钟内玻璃内应力得以明显缓解的温度。 (ASTM C-336)


ASTM hardness number. Depth (in thousandths of an inch) of penetration of an indentor into a rubber specimen under loads and conditions specified in ASTM D-314. While suitable for most common grades of rubber, ASTM hardness number is not applicable to extremely hard or soft rubbers.

ASTM硬度值。根据ASTM D-314规定的负载和条件,压痕器穿透橡胶试样的深度(千分之一英寸)。虽然ASTM硬度值适用于最普通的橡胶等级,但它不适用于极硬或极软的橡胶。
