公稱壓力

一般是指在常溫下，保護管所能承受的靜態外壓而不破裂，試驗壓力一般采用公稱壓力的1.5倍。實際上，允許工作壓力不僅與保護管材料、直徑、壁厚有關，而且還與其結構形式、安裝方法、置入深度以及被測介質的流速、種類有關。

熱電偶絕緣電阻：

常溫絕緣電阻的試驗電壓為直流500V。測量常溫絕緣電阻的大氣條件為：溫度15～35℃，相對濕度45%，大氣壓力86～106Kpa。

對于長度超過1米的熱電偶，它的常溫絕緣電阻值與其長度的乘積不小于100兆歐·米，

即：Rr·L≥100MΩm L＞1m

式中：Rr-熱電偶的常溫絕緣電阻值，MΩ；

L-熱電偶的長度，m。

對于長度等于或不足1米的熱電偶，它的常溫絕緣電阻值應不小于100 MΩ。

熱電阻絕緣電阻：

常溫絕緣電阻的試驗電壓可取直流10～100V任意值，環境溫度應在15～35℃范圍內，相對濕度應不大于80%，常溫絕緣電阻值應不小于100 MΩ。
