MAINTENANCE ACTIVITY CARD: Card used in the management of maintenance activities. (See: EMMA)
维护保养卡片：用于维护保养管理的卡片 MENDER: The acronym MENDER stands for: MENDER： 每个字母代表的含义为： MEASURE - PHYSICAL ITEMS 测量 – 实物
EVALUATE - RESULTS SCIENTIFICALLY 评估 – 结果
NEEDS - IDENTIFY AND RECORD 需求 – 鉴别和记录 DEVELOP - ACTION PLAN 制定 – 行动计划
EXPENSES - CONSIDERED AND APPROVED 费用开支 – 考虑过并被批准的 REPORTING – RESULTS 汇报 – 结果
MENDER is a predictive maintenance program that is designed to define a machine's condition and recommend the action required to correct any faults in order to reduce machine downtime for mechanical delays.
MENDER 是一种预测性的维护保养方法，用于跟踪监测机器的状况，并采取必要的行动来改正存在的错误以此降低机器停工的时间。
METALURGICAL SAMPLE: A sample slug, part, or section of a carbonized, or hardened steel used for testing to determine structure, hardness, case depth, etc.
