In each three orientations at vibration (1055Hz) with 2.0mm P-P amplitude. 2012-7-2 Page:4/9SPECIFICATION FOR EARPHONE編號NO.項目ITEM規格SPECIFICATION3-3拉力實驗Pull test在線材伸張方向用1.5kg拉力,持續60秒.線材不能被拉斷,也不能有電气方面問題.單線拉力不少于1kg,不大于3kg的測試規范.Apply 1.5kg of positive load in the direction of the cord extension to pull out and keep it under this condition for 60 seconds. The cord must not be broken. It must not have any electrical problems.Single cord: No less than1kg, no more than 3kg3-4湿度特征實驗Humidity Characteristics溫度：40土2，相對濕度：9095%環境中48小時無損傷； 2小時後自然干噪。No any default are found after 48 hours in 9095% relative humidity at 402 and 2 hours drying under normal condition.3-5結合實驗(接口實驗)Connection test (plug and jack part)把插頭插進插座在垂直方向上用1kg的力按住插頭保持30秒，把這個負重分別用在上、下、左、右四個方向，用手夾住插頭部位插拔3000times以上，每分鐘20-30次，每500次檢查一次功能和外觀要求無短路、斷路、針離，並且耳機能夠正常動作。插座無接触不良等現象.Apply 1kg of positive load, Firmly insert the plug into jack vertically and keep it under this condition for 30 seconds. Repeat this action, in and out, in and out for more than 3000 times, about 20-30 times per minute, inspects the plug appearance and the function every 500 times, requests no short-circuits, open circuits, no needle leave, and the earphone can normally act. Apply 1kg load try the plug in the 4 directions (up, down, right and left) individually. The jack portion must not have a conductive defect.3-6高溫高濕保存實驗High-temperature and high-humidity storage test在45+2相對濕度95%,環境中保存96小時,然后在常溫常濕下保存24小時,外觀和音質特性無問題出現Keep the product at 45+2 and 95% RH for 96hours, and then leave it at room temperature and humidity for 24 hours.Problems with external appearance, sound quality characteristics must not occur. 2012-7-2 Page:5/9SPECIFICATION FOR EARPHONE編號NO.項目ITEM規格SPECIFICATION3-7低溫保存實驗Low- temperature storage test在-252的環境下保存96小時,然后在室溫下保存24小時,外觀和音質特性方面無問題出現.Keep the product at a temperature of 252 for 96 hours, and then leave it at room temperature and humidity for 24 hours.
