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

一、皮革耐（nài）撓性試驗機（jī）說明:

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

二、皮革耐撓性試驗機目的（de） :  

             用於沙發上的（de）皮革如果有良好的抗彎折的（de）特性, 生產出來的沙發便不容易起皺接（jiē）, 沙發會更美觀（guān）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（shì）驗機適用於3毫米厚度以下的皮革.

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

三、皮革耐撓（náo）性（xìng）試驗機技術參數:

                試片: 70*45mm

                彎折（shé）角度: 22.5

               彎折速度: 100±5cpm

                計數器（qì）: 0~999,999（六位數）

                電源: 220伏300瓦
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,其打開的夾縫應不少於待測試皮夾的2倍。

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

調整上夾使其（qí）底邊跟下固（gù）定夾（jiá）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.

將皮革沿長邊對摺（zhé）（測試（shì）麵朝內）, 將已對摺的（de）皮革按下圖（a） 的樣子,摺邊擱在上（shàng）夾突（tū）出的（de）邊上，末端則貼近由鎖緊螺絲造成的限位上。

把未有夾緊的那（nà）一頭往外然後向下拉, 把兩個裏麵併攏, 然後將開口端按圖（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.
