Initial tack-GB/T 4852-2002

Preparation:

1. Testing equipment: Tack testing machine as above  picture

2. 14# steel ball

3. Tested sample

Testing  Procedure:

1. Recording how long the steel ball has  runned.

180° peeling  strength-GB/T 2792-1998;

Preparation:

1. Testing equipment: 180° peeling testing  machine

2. Tested  Sample: 25.4mm-width,300mm-length

3. Stainless  Steel plate,125mm-length,50mm-width,1.5-2.0mm-thickness.Surface of steel plate  must be smooth

4. Testing  enviroment: Temperature-23°℃,Humidity:  65%

Testing  Procedure:

1. To clearn the steel plate with abluent and no dust  cloth.Repeat this action until the steel plate is absolutely clean.

2. Stick the tested tape on cleaned steel plate.Use  compression roller(2.5kg) to compress the tape back and forth for at least 3  times(Speed: 12cm/s).(To make sure the tape is sticked on surface of steel plate  completely,and definitely no gas between them.

3. After above procedure,leave the sample there for about 3  minutes.

4. Install the sample to testing machine and start  testing.

5. Record the tensile force.Unit:N/25mm or kgf

6. Testing for more than 3 times and get average result.

Holding power-GB/T 4851-1998

Preparation:

1. Testing equipment,including 1kg weight,stainless steel  plates

2. Sample: 25.4mmX25.4mm.

3. two pieces  of stainless steel plates.Surface of steel plate must be  smooth

 

Testing  Procedure:

1. To clearn the two pieces of steel plates with abluent and  no dust cloth.Repeat this action until the steel plate is absolutely clean.

2. Stick the tested tape on cleaned steel plates.Join them  together.One steel plate on the above is sticked with area 25.4mmX25.4mm,the other could be sticked with more length such as  25.4mmX30mm.Use compression roller(2.5kg) to compress the tape back and  forth for about 1 minute(Speed:12cm/s).(To make sure the tape is sticked on  surface of steel plate completely,and definitely no gas between them.

3. After above procedure,leave the sample there for about 20  minutes.This is under normal temperature.

4. Temperature of testing machine will be set at the  temperature we need.Temperature remains constant.Put the steel plates into  testing machine.The steel plate which is sticked with area 25.4mmX25.4mm must be put on the above side.The weight which is in  1kg will be hung there.Close the door of testing machine.

5. Record how much time the weight is hung there.

6. Testing for more than 3 times and get average result.

 

 

 

In the lab,every procedures need to be followed accurately  and well-finished seriously.Otherwise the result is not correct.Above is  approximate procedures for your reference only.I translate by myself.Hope it is  helpful.
