Moisture resistant microbial penetration tester

I. Introduction:

HBJ button tester, can be equipped with NK, HP series push-pull meter and special fixture, specially used to measure the force of the button or get rid of the destructive force of the clothes.

Testing the fixed strength of buttons and buttons is a very important standard, especially in the design and manufacture of infant and children's clothing.

The measurement of a certain force applied to the button fastening ornament shall be recorded by a force instrument.

Ii. Purpose:

The purpose of the HBJ button tester is to define the responsibility of the garment manufacturer to ensure that buttons, buttons and fasteners are properly fastened to the garment and to prevent the risk of the button being removed from the garment and being swallowed by the infant.

Therefore, all buttons, buttons and fixed ornaments on the garment (which can be put into the small object measuring device) shall be tested by the button tester.

Iii. Significance and Function:

1. The test method of this instrument is used to measure the strength of the vertical pull test on the button and the garment without pulling the button and button off the garment.

2. The sewing specifications required for this method shall be in accordance with the standards set by the button manufacturer.

3. This test method is used to establish the correlation between different wearing environments, and to compare various types and brands of different knobs.

4. This standard may contain hazardous materials, operations and instruments, and all possible safety problems in use are not listed in the standard.

It is therefore the user's responsibility to establish relevant safety and health rules and to determine appropriate rules prior to use.

5. All buttons need to be stitched on the fabric with chains.

6. According to the test requirements, when the button size of ZUI is larger than 6mm or less than/equal to 6mm, the button shall be able to withstand the tension of 90N and 50N respectively.

V. Installation method of the Instrument:

1. Installation method of the frame:

This instrument can be installed on the table to make the instrument more stable.

Make sure the working table is level during installation so that the test results are accurate.

Please refer to (length × width :300mm×200mm) for installation.

2. Installation method of push-pull meter:

A. Loosen the four M4 ×15 hexagon socket cylindrical head screws on the mounting plate of the dynamometer with M4 wrench, and remove the mounting plate of the dynamometer;

B. Install the push and pull timing of HP series (digital display push and pull meter), use M4 hexagon socket wrench to insert 4 M4×10 hexagon socket screws in the accessory bag through the 90×40 holes on the mounting plate of the dynamometer and screw them into the 4 M4 threaded holes of the dynamometer, and install the dynamometer on the mounting plate of the dynamometer;

Or use a phillips screwdriver to pass the 4 M3×10 cross-slot disc head screws in the accessory bag through the dynamometer and install the dynamometer on the mounting plate of the dynamometer.

The 145×30 holes on the mounting plate are screwed into 4 M3 threaded holes of the dynamometer;

C, installation NK series (pointer push tension meter) of push pull timing, with a phillips screwdriver push pull the meter on the back cover of 4 M x 10 screw off, will the attached bag 4 pieces of M3 x 14 phillips screws through the dynamometer mounting plate on the 145 x 30 mounting holes, screwing in dynamometer 4 M3 threaded hole on the back cover (unload M3 screw thread hole of x 10);

D. After installing the push-pull meter, reinstall the mounting plate of the dynamometer on the rack with the M4 hexagon socket wrench.

3. Installation method of upper fixture:

Install the upper fixture on the test rod of the push-pull meter with the internal thread connecting hook in the attachment.

4. Installation method of base fixture:

Using the 2 M6 screws in the attachment and the M6 hexangular plate hand, connect the base fixture and the machine stand firmly.

Vi. General Test Operation Process:

1. Place the cloth with button fixator on the base fixture (under the pressure block with concave shape), keep the button facing up, and push the push rod handle to hold the cloth (and ensure that the fabric is pressed).

2. Rotate the clamping device counterclockwise to make it open.

3. If HP series (digital display push-pull meter) is used for push-pull timing, turn on the power and wait for the LCD to display zero.

4. Install the push and pull timing of NK series (pointer push and pull meter), press the switch button to return the finger to zero.

5. Shake the hand wheel of the turning body to make the clamp move downward and grasp the button.

6. Shake the hand wheel of the turning body to make it move upward.

Vii. Daily Maintenance and maintenance:

1. Do not overload the instrument. The rated load of the instrument is 300N.
