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

一、皮革（gé）耐撓性試驗機說明:

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

二、皮革耐撓性試（shì）驗機目的 :  

             用於沙發上的皮革如果（guǒ）有良好的抗彎折的特性, 生產出來的沙發便不容易起皺接, 沙發（fā）會更（gèng）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（nài）撓性試驗機技術參數:

                試片: 70*45mm

                彎折角度: 22.5

               彎折速度: 100±5cpm

                計數器: 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（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）上夾使其底邊（biān）跟（gēn）下固定夾的上邊平行。

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

把未有夾緊的（de）那一（yī）頭往外然後向（xiàng）下拉, 把兩個裏麵併攏, 然後將開口（kǒu）端按圖（c）夾緊在下夾,注（zhù）意不要（yào）過（guò）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.
