環境條件
之分類
單一環境參數分類(六大類)
n
自然環境
(Natural environments)
n
氣候環境
溫度(高、低溫);溫度變化(溫度循環、衝擊);濕度
自然環境主要是由於氣象、地形等因數所引起
(穩態、循環濕度);大氣壓力(高、低壓及真空);降
的。
落物(雨淋、雪、冰雹);輻射; 等項目。
n
機械環境
機械衝擊(即非穩態振動),如自由落體、跌落、外物碰
n
誘發環境
(Induced environments)
撞;穩態振動(包括週期性的正弦振動及非週期性的隨機
誘發環境則為系統與裝備在搬運、組裝及操作
振動)、音響(噪音)。
時所引起的。

電磁環境
電磁環境又可分為電場(包括靜態場和交流場)、靜電放電、閃
電雷擊;磁場(包括靜態場和交流場)、導線傳送干擾等。
環境效應分析
n
生物環境
生物環境又可分為:具有生物作用的物質[包含植物(包含霉與
在某種特定的應用場合下,環境對於產品
菌)]及動物。
的影響有下列三種情形:
n
具機械作用環境
包括砂、塵、及泥等具有機械作用的顆粒。
1.周圍媒介的條件,通常為空氣或水。
n
具化學作用環境
包含海水鹽霧、二氧化硫、硫氫化物、臭氧、有機碳化合物等具
化學作用的物質。
2.與產品連接結構的條件,亦即產品載具。
3.來自外部根源或活動的影響。
