皮（pí）革耐撓性試驗機產品簡介：
本試驗機用用（yòng）於沙發麵料的撓性試驗.
電源: 220伏300瓦
設計標準： EN ISO 5402

一、皮革耐撓性試驗機說明:

            使用（yòng）耐橈專用夾具測試皮革表麵在不斷受外力作（zuò）用下皮料發生皺摺和破損的情形，本試（shì）驗機用用於沙（shā）發麵料的撓性試驗.
 

二、皮革（gé）耐（nài）撓性試驗機目的 :  

             用於沙發上的皮革如（rú）果有良好的抗彎折的特性, 生產出（chū）來的沙發便不容易起皺接, 沙發會更美觀耐用.

         Purpose: If the leather use for the sofa have a good flex resistance properties, the product will have little chance to become winkle, and the product will be more durable and more comfortable.

               本皮革耐撓性試驗（yàn）機適用於（yú）3毫米厚度（dù）以下的皮革.

                Applicable to all types of leather below 3.0 mm in thickness.

三、皮革耐撓性試驗（yàn）機技術參數:

                試片: 70*45mm

                彎（wān）折角度: 22.5

               彎折速度: 100±5cpm

                計（jì）數器: 0~999,999（六位數）

                電（diàn）源: 220伏300瓦（wǎ）
設計標準： EN ISO 5402 

 1）      Open the upper and lower clamps so that the gap is at least twice the thickness of the test piece.

打開上、下夾,其打（dǎ）開的夾縫應不少於（yú）待測試皮夾的2倍。

       2）      Turn the upper clamp so that its lower edge is parallel to the upper edge of the fixed lower clamp.

調整（zhěng）上（shàng）夾使其底邊跟下固（gù）定夾的上邊平行。

      3）      Fold the test piece in two with the surface to be tested inwards so that the two longer sides are brought together. Clamp the folded test piece as shown in below figure （a） with the folded edge against the ledge and the end against the stop formed by the clamping screw.

將皮（pí）革沿長邊對摺（測試麵朝內）, 將已對摺（zhé）的皮革按下圖（a） 的樣子,摺邊（biān）擱（gē）在上夾突出（chū）的邊上，末端則貼近由（yóu）鎖緊螺絲造成的（de）限位上。

把未有夾緊的那一頭往外然後向下拉, 把（bǎ）兩個裏麵併攏, 然（rán）後將開口端按圖（c）夾緊在下夾,注意不要過份夾緊以致夾壞皮革，並且要跟對摺麵垂直。

       5）      Run the machine for the required number of flex cycles selected from the following list:

Dry flex: 500；1000；5,000；10,000；20,000；25,000；50,000；100,000；150,000；

        200,000；250,000 CYCLES

 按所需測試週期開始測試。

       6）      cutting of sample: A rectangle shaped sample 70 ±1 mm x 45 ±1 mm.

       7）      樣辦尺寸: 70 ±1 mm x 45 ±1 mm.

      4）      Draw the free corners of the test piece outward and downward around the clamp as shown in figure （b）. Bring the inner surfaces together and clamp the free end in the lower clamp as shown in figure （c）, with the part of the folded test piece in the clamps vertical and using no more force than is necessary to make the leather just taut.
