型式试验：对按照某一设计要求而制造的防爆电动葫芦所进行的试验，用以检验这一设计要求是否符合一定的规范。
Type test: the test on the explosion-proof electric hoist manufactured according to a certain design requirement to check whether the design requirement meets certain specifications.
常规试验：也叫出厂试验，对防爆电动葫芦每个器件或设备在制造中或完工后所进行的试验，用以判明器件或设备是否符合某项标准。JDG金属穿线管 不锈钢链板 隔离墩模具 检查井钢模具 流水槽模具 阶梯护坡模具 护坡砖模具 遮板模具
Routine test: also known as factory test, the test of each device or equipment of explosion-proof electric hoist during manufacturing or after completion, to determine whether the device or equipment meets a certain standard.
介质试验：是检验介质电气特性的各种试验的总称，包括：绝缘、静电、耐压等。
Dielectric test: it is the general term of all kinds of tests for testing dielectric electrical characteristics, including insulation, static electricity, withstand voltage, etc.
抽样试验：对防爆电动葫芦中随机抽取的若干样品进行试验，也是用来判明样品是否符合某项标准的。
Sampling test: a number of samples randomly selected from explosion-proof electric hoist are tested, which is also used to determine whether the samples meet a certain standard.
寿命试验：确定防爆电动葫芦在规定条件下可能达到的寿命的试验，或者是为评价分析产品的寿命特征而进行的试验，属破坏性试验。
Life test: the test to determine the possible life of explosion-proof electric hoist under specified conditions, or the test to evaluate and analyze the life characteristics of products, which is destructive test.
耐受试验：在包括一定时间内为一定目的所采取的特定运行等规定条件下，对防爆电动葫芦进行的试验，如反复操作、短路、过电压、振动、冲击等，属破坏性试验。
Withstand test: the test on explosion-proof electric hoist under specified conditions including specific operation for a certain purpose within a certain period of time, such as repeated operation, short circuit, overvoltage, vibration, impact, etc., is a destructive test.
