文章導讀 近日，一些用戶問道：防水試驗裝置IPX7/8測試樣品應該如何放置呢？以下詳細規範和技術要求：

在電子設備日趨小型化、移動化、戶外化的今天，“防水”已不再是一项锦上添花的功能，而是决定产品可靠性与市场竞争力的关键指标。IPX7与IPX8作为国际公认的外壳防护等级（IEC 60529、GB/T 4208-2017），分别代表“短时浸水”与“持续潜水”两大严苛场景。

近日，一些用戶問道：防水試驗裝置IPX7/8測試樣品應該如何放置呢？以下詳細規範和技術要求：

一、IPX7與IPX8測試的樣品放置規範

IPX7（防浸型）

放置位置：樣品需完全浸入試驗箱水體中，底部距離水面至少1米（部分标准允许0.85-1.5米范围）。

方向要求：通常按産品正常工作姿態放置（如手機屏幕朝上），若需多角度測試，需分次調整樣品方向。

持續時間：標准爲30分鍾，水溫建議5℃~35℃（與樣品溫差≤5℃）。

IPX8（持续潜水型）

深度要求：由廠商與客戶協商，通常爲1.5~30米水深（需明确压力值，如30米对应约300kPa）。

固定方式：樣品需固定在專用托盤或支架上，確保測試中無位移。

密封檢測：部分設備會配合真空泵檢測漏點（通過觀察氣泡判斷密封性）。

二、防水試驗裝置IPX7/8操作流程

預處理步驟

檢查水箱密封性（不鏽鋼罐體需爲SUS304材质，直径≥600mm，高度≥1200mm）。

確認水質清潔，無雜質（避免堵塞傳感器或影響觀測）。

樣品安裝

將樣品置于設備腔室內的托盤上，鎖緊罐蓋螺栓（對角線順序擰緊）。

關閉手動排氣閥，設置參數（如IPX8需設定保壓時間、測試深度等）。

測試啓動

通電後啓動加壓系統（220V电源），实时监控压力表和水位。

IPX8測試可能需抽真空（真空泵壓力範圍-90kPa~0）。

以上關于防水試驗裝置IPX7/8測試樣品放置的介紹，先到這裏。

"Yes, a beautiful story is a thing Ned Ferry loves with a positive passion." In gratitude for Charlotte's word she sank backward in a long obeisance. "May it please your ladyship, dinner is served. Oh, Mr. Smith, I've been listening to Mr. Gholson talking with aunt Martha and Estelle; I don't wonder you and he are friends; I think his ideas of religion are perfectly beautiful!" As she left me, Ned Ferry came out with a sad face, but smiled gladly on me and caught me fondly by the arm. On hearing my brief report he saddened more than ever, and when I said I had promised Jewett he should hand his sword to none but him, "Oh!"--he smiled tenderly--"I don't want to refuse it; go in and hang it at the head of his bed as he would do in his own tent; I'll wait here." "But I thought the' was fi-ive letters," said the Squire as we were about to leave the board; at which Mrs. Wall mumbled to him to "hush up;" for the fifth was to Cécile. The constable laughed gently and stroked his moustache. His theory about the condition of the individual before him slowly developed. "I am not here about that," he said, "at least, not for the present. I am afraid I have some bad news for you. I am speaking to the lady who is known to people generally as Countess Lalage." and declare my principles in my next. to die. There were plenty of strong, willing hands to help carry Si from the caboose to the wagon. It was strange how tender and gentle those strong, rough farmers could be in handling a boy who had been stricken down in defense of his country. Annabel's face was as red as a hollyhock over the way that everybody assumed her right to be next to Si, and those who could not get a chance at helping him helped her to a seat in the wagon alongside of him, while the dethroned Maria took her place by her father, as he gathered the reins in his sure hands and started home. Maria had to expend some of the attentions she meant for Si upon Shorty, who received them with awkward confusion. "Should think they was bride and groom, if they wasn't so old." "'Tention!" commanded Si. "Fall in single rank 'cordin' to your size. Tall boys on the right, short ones on the left, medium in the center. Gid Mackall, you're the tallest. You can go there to the corner o' the platform and let the others form on you." At the word the boys made a rush for the man who was quietly walking off. As they ran they threw stones, which went with astonishing precision and force. One of them struck the man on the head and felled him. Then the boys jumped on him and began pounding and kicking him. Si and Shorty came up, pushed off the boys and pulled the man to his feet. He was terrified at the onset which had been made upon him, and could not understand its reason. "The regiment will go on," reported Orderly-Sergeant, "but Co. Q will stay behind to bury the dead, gather up the arms and things, and then bring up the brigade ammunition train." "Do you know why there isn't?" Dodd's voice was a shock, stronger than before. PUBLIC OPINION SIX Before committing the body to the ground, he said a few words in praise of the dead man. He spoke of his generosity to his neighbours, his kindness to his dependents, his excellences as a husband and a father. "This, brethren, was indeed a man after God's own heart. He lived simply and blamelessly, contented with his lot, and seeking no happiness that did not also mean happiness to those around him. The call of the world"—by which Mr. Barnaby meant Babylonish Rye—"fell unheard on ears attuned to sweet domestic sounds. Ambition could not stir him from the repose of his family circle. Like a patriarch of old, he sat in peace under his vine and his fig-tree...." "Aye, Master," said another, "he is laid up but I fear he has forgot the shrieving. However, he will never again say guilty or not guilty in a jury-box, or kiss the book in justification of bail!" HoME 京香julia与翔太 mide ENTER NUMBET 0015yschain.com.cn
