Input Test 安規(guī)主要測(cè)試要求 Building Networks for People 1. Input Test Building Networks for People 適用情形 : 有開(kāi)孔之外殼 A. 上蓋之開(kāi)孔 i) not exceed 5mm in any dimension. ii) not exceed 1mm in width regardless of length iii) be so constructed that direct, vertical entry of a falling object is prevented from reaching such bare parts by means of trap or restriction.(如下圖例 ) (圖例 ) EX: 左圖之綠色虛線部分不可超過(guò)５ mm 2. Accessibility Test : Building Networks for People B. 側(cè)邊之開(kāi)孔 a. not exceed 5mm in any dimension. b. not exceed 1mm in width regardless of length. c. 開(kāi)孔位置適當(dāng) , 並在其 5176。角範(fàn)圍的定義 (如下頁(yè)附圖 ) 2. Accessibility Test : Building Networks for People 以類(lèi)似百葉窗的開(kāi)孔方式 , 使其 5176。角的傾斜面上時(shí)不可 產(chǎn)生失衡現(xiàn)象及造成使用者及維修人員 產(chǎn)生危險(xiǎn)之情形 . 9. Impact Test Requirement : 以一直徑 50mm, 重為 500177。 而產(chǎn)品 內(nèi)部會(huì)直接接受 or 傳送 Tele 所需電壓的部分即稱(chēng)為 TNV circuit (TNV circuit 分為三種類(lèi)型 ) 。 EX: 純 ISDN產(chǎn)品 , DI300 Building Networks for People ? TNV2 Circuits Tele 產(chǎn)品之相關(guān)規(guī)定 whose normal operating voltages exceed the limits for an SELV CIRCUIT under normal operating conditions for telephone ringing signals, voltages such that the signal plies with the criteria of either clause (for Europe) or clause (for US). 一般而言 , TNV2 的線路是針對(duì)連接至 indoor tele 線路 ,
