INSTRUCTION TO THE USER OF THE TEST CHAIN 6306-1
SUBJECT: TEST CHAIN ACC. To IEC 60598-1
Now there is new standard amendment from year 2000.
The value of the resistance of the test chain at 200 gram load is specified to 2,5ohm/meter.
SPEC:
2,5 ohm/meter +/- 20 % at load 200 gram/m
Handling instruction－see below, Material: 37% Zinc/ 63% Copper
One important point is to CLEAN TO CLEAN the chain after EAC usage with alcohol to achieve the correct start value !!! Control also that the resistance value of the chain is 2,5 ohm/meter. If not 2,5 ohm/meter you have to stretch/expend the chain several times by hand so that it successively get lower and lower value until 2,5ohm/meter.
一、燈具試 驗 鏈概述：
滿足IEC60598&GB7000.1&EN60598-14試驗要求，依據GB7000.1 IEC60598-1 .26.3 條款圖29要求設計制造，主要用于燈具未絕緣、可觸及而且相反的SELV部件的意外短路保護試驗。由銅鋅合金（Cu63%，Zn37%）制成，未作任何表面處理和涂覆，200g/m負載拉伸時阻值在2.5±20%Ω范圍之間。
二、使用方法：
測量試 驗 鏈阻值，確保其范圍為2.5±20%Ω。
測量被SELV部件兩極的空間距離，記為X，單位（厘米/cm）。
試 驗 鏈兩端懸掛標準配重=15*X*g或者較大250g的配重。
在被測樣品合適位置安裝熱電偶，接通溫度巡檢儀。
樣品接入0.9~1.1倍額定電壓的電源。
放置試 驗 鏈，進行短路試驗。
注意：試 驗 鏈熔化可成造成燙傷
