此提案僅供審核和評論(此時不進行投票)。請注意，關于初步審查文件的意見將不會通過

CSDS收到提案作者的回復。不過，提案作者將被要求審查意見，并根據作者認為適當的方式調

整提案和/或支持理由。

初步審查過程是一種非正式機制，為作者提供了在UL到標準制定過程下一階段之前完善其

提案的機會。

在某些情況下，提案的作者可能會選擇中止。在這種情況下，作者在初步審查結束后不需要

做任何事情。通常，這個過程的下一步是更加正式的STP投票和利益相關者審查過程。只有在

STP投票和利益相關者審查過程中發表的評論才會在CSDS中提供回應。

為了方便審查，現有要求的擬議增加顯示為下劃線，建議刪除內容列出。

6詞匯表

6.1為了本標準的目的，適用以下定義。

6.2DUT-被測設備。

6.3能源存儲（ES）系統-通過電化學或其他方式提供儲存能量的設備，供以后使用以供應公

用電網或本地電網。能量存儲系統可以利用以下技術之一：

a）電化學能量儲存系統-由二次電池，電化學電容器，流動電池或混合蓄電池-電容器系統

組成，用于存儲能量和任何可根據需要提供電能的相關控制或裝置。

b）化學能源儲存系統-由供氫設備或與燃料電池電力系統或發甩機組合的其他燃料供應設備組

成，以將燃料轉換為電能。

c）機械能源儲存系統-包括通過壓縮空氣，抽水或飛輪技術儲存能量的機械手段，以及相關的

控制和系統，可用于運行發電機以根據需要提供電能。

d）熱能儲存系統-包括使用加熱流體（如空氣）作為儲存能量的手段以及相關控制系統的系統，

可用于運行發電機以根據需要提供電能。

6.4電擊危險-通過直接接觸保護外殼中的開口和/或危險電壓電路和可觸及部件之間的絕緣不

足，可能使人員暴露于危險電壓電路。

6.5外殼-能量存儲系統的外蓋，可保護其內容物。

6.6燃料電池系統-將燃料和氧化劑形式的化學能轉化為電能的設備，具有反應的熱和副產物。

6.7危險電壓-

在美國，電壓超過30Vrms/42.4Vac峰值或60Vdc。

在加拿大，電壓超過30Vrms/42.4Vac峰值或42.4Vdc。

6.8絕緣水平-以下是電絕緣水平：

a）基本-單級絕緣，提供防電擊保護。如果絕緣層發生故障，單獨的基本絕緣不能提供防電擊

保護。

b）雙重絕緣-絕緣包括基本絕緣和輔助絕緣。

c）功能絕緣-絕緣僅對設備正常工作是必需的。絕緣功能絕緣不能防止觸電。但是，可能會降

低點火和起火的可能性。

d）加強絕緣-在本標準規定的條件下，提供相當于雙重絕緣的觸電防護等級的單一絕緣系統。

術語“絕緣系統”不意味著絕緣體必須在一個均勻的部件中。它可以包括幾個不能作為基本絕緣

和輔助絕緣測試的層。

e）輔助絕緣-除了基本絕緣外，還應采用獨立絕緣，以減少基本絕緣故障時的觸電危險。

6.9限制訪問位置-以下兩種能力存儲系統設備的位置：

a）只能由服務人員或被指示使用該地點限制理由的使用者以及應采取的預防措施獲取通路;和

b）訪問是通過使用工具或鎖和鑰匙或其他安全手段進行的，并由負責該位置的機構控制。

6.10室內環境-被認為是25±5°C（77±9°F）范圍內的溫度。

6.11安全關鍵電路/組件-在15.2的安全分析中確定的那些依賴于安全性的電路或分立組件。

7非金屬材料

7.1用于外殼的材料應符合“高分子材料標準”?電氣設備評估標準“UL746C”，“外殼要求

的第III路徑”或“聚合材料性能評估標準”C22中概述的適用外殼要求。2號0.17。

7.2在評估使用非金屬材料的外殼時，應考慮(a)-(e)中的以下因素。對于非金屬外殼，所

有這些因素都將考慮熱老化。聚合物外殼的尺寸穩定性通過符合模具應力消除測試來解決。以下

因素(a)-(e)的適用性可以通過本標準的測試來確定

a)抗沖擊;

b)抗壓性；

c)異常操作；

d)嚴重條件;和

e)模具應力消除變形。

7.3系統中用作電氣絕緣的材料應能抵抗會導致觸電，火災或其他安全隱患的劣化。絕緣材料與

危險活性部件直接接觸或接近危險的活性部件,符合“聚合材料標準”中的“材料特性注意事項”

表格6.1?電氣設備評估中使用的評估，UL746c或“性能評估標準”高分子材料C22.2第0.17

號應另外符合該標準中概述的絕緣標準，除非作為已被評估為合適組分標準的組分的一部分使用。

絕緣布線符合第11節中概述的要求。

7.4墊片和密封件依賴于安全性，應確定適合其最終用途中預期會暴露的環境條件和化學物質。
