漆膜冲击器操作程序

八戒

SCOPE AND LIMITATIONS使用范围和限制

This procedure is limited to the operation of the test apparatus specified in the national standard GB/T 1732-93.
本操作程序仅限于国标GB/T 1732-93 所规定的漆膜冲击器的使用。

HEALTH AND SAFETY健康和安全

Carry out an assessment of the risks involved in handling the samples and chemicals used; refer to the relevant safety data sheets and suppliers’ literature. Record the details. Wear appropriate personal protective equipment. Work in accordance with local environmental and Health & Safety rules.
对危险进行评估包括使用过的样品和化学品的处理；参照相关的安全数据手册和供应商所提供的资料。试验中记录所有细节。穿好适当的个人防护用品。所有工作要符合当地的环境保护和健康与安全的法律法规。

PROCEDURE操作程序

This SOP should be used in conjunction with the manufacturers operating manual and the relevant national standard.
本操作程序的使用应结合制造商的操作手册和相关的国家标准。
一．使用前的检查与调整(Check and adjustment before the operation)

1）
Ensure that the punch center and the panel anvil are at the same vertical;If any deviation, adjust the screw on the indenter.
检查冲杆中心是否与枕垫块凹孔中心一致，若有偏差时，可调整冲击块紧母上的内六方镙钉。

2）
Ensure that the height marker is on zero graduation: Fall down the cylinder to check ,if any deviation ,adjust the two screws of the height marker.
检查定位标是否对零线：将重锤放下观察定位标上刻线是否与零线重合，有偏差时可调整定位标两侧的螺钉。
二．
使用说明(Operation)：

1）
Prepare the film panel coated with the schemes under test; the substrate should
Be tinplate with size 50mmx120mmx0.3mm or ,thin steel panel by GB/T 708 with size 65mmx150mmx0.45~0.55mm ( for filler film test).
按照产品标准所规定制备样板;底材使用50mmx120mmx0.3mm的马口铁或
符合GB708 技术要求的薄钢板，尺寸为65mmx150mmx0.45~0.55mm（供测腻子时使用）
。

2）
Place the specimen firmly over the hole which is situated in a die in the anvil and the film should be upside.The point of the impact is at least 15mm from the edge of the panel ;when tested several times on the same panel , the points should be at least 15mm from each other.
把样板放置在枕垫上紧贴与凹孔上，漆膜朝上，受冲击点距样板边缘不少于15毫米；一个样板测量多次时，应使每个冲击点边缘相距不少于15毫米；

3）
Fix the controller at the required height in the graduated guide-tube ;and press the control screw , the cylinder will fall on the indenter and then transfer the impact on the film panel .
用控制器螺钉固定好高度，按压控制螺钉，重锤即自由落在冲杆上，冲杆将冲击力传到样板上。
4)
Lift the cylinder and it will be hang by the controller. Take out the panel to observe by four times magnifier or visually( if allowed by the standard).If the film has no crack ,crimple or peeling off, increase the height until the film is broken,or it can bear the impact of 50cm.
The film impact is the most height that the film can bear without damage when
The cylinder weighing 1kilo falls on it, expressed unit by cm*kg.
将重锤升起，重锤的挂钩自动被控制器挂住，取出样板，用四倍放大镜或目测（如果标准允许目力观察），当漆膜没有裂纹，皱皮或剥落现象时，可增大重锤下落高度，直至漆膜破坏，或能经受50厘米高度的冲击为止。
每次试验都应在不同的样板位置进行。根据漆膜的坚牢程度，每次重复时增加高度2~10厘米。
5)
The film impact is the most height that the film can bear without damage when
The cylinder weighing 1kilo falls on it, expressed unit by cm*kg. The deviation of the two successive results should be within +/- 1cm .
漆膜的冲击强度以1公斤重锤冲击漆膜而不致使其引起损坏的最大高度以厘米表示之。
两次测定之差应在+/-1厘米范围之内。
6）
Test should be under the condtition that the temperature within 25+/-1C and humidity less than 70%.
在空气温度25+/-1C 和相对湿度70%以下条件进行试验。
