Equipment

Package Contents

Optional Extras

Universal Sample Cutter (RL-A80-005)
Allows for simultaneous cutting of 50mm and 115mm ø samples Suitable for film and paper-based samples with a thickness between 6 and 250 microns (μm)

Abrasion Tester Head (HAN-B1002RT4HEAD-S)
A more aggressive test, useful for assessing through cure of UV coatings or high abrasion transit testing.

Solvent Resistance Test Head (HAN-B1002RT4HEAD-W)
Used to test the water, detergent, solvent or fat resistance of inks and coatings.

Operation

Assembly

• Remove the instrument from all packaging. Retain the packaging so that the equipment can be returned for calibration and service repairs.
• Place the instrument on a suitable bench and put the supplied bull’s eye spirit level on the instrument bed next to the rotating sample holder.
• Check the instrument is level, the bubble should be contained within the circle in the centre of the spirit level. If the weight platform is not level, use the supplied spanner to adjust the feet of the instrument.

Powering the instrument

• Use the supplied mains lead to connect the instrument to a suitable mains supply.
• Switch the instrument on using the button at the rear of the instrument.

Set Test Conditions

Selecting test conditions

Select a test condition that is close to the failure point of the material. Increasing the test pressure increases the severity of the test. The failure point can be found by trial and error, several tests should be carried out using increasing weights until marking of the substrate and/or deterioration of the coating is visible.
Test pressure – The weight set provided allows for 3 test pressures:

• To select the reported test pressure* press the +/- buttons to cycle through the available options (fig 2).
• *Refer to table for mass required to achieve pressure.

Sample Preparation

Sample selection

• Upper sample – The 50mm diameter sample is typically cut from a sample of printed material. Select an area for testing, it is usual to test areas that are MOST likely to fail; these include any heavy ink build areas or spot colours.
• Lower sample – The lower sample is 115mm in diameter – This can either be another sample of the printed material or white paper to see clearly see the ink transference.

Using the sample templates

• Identify the area of the printed sample to be tested.
• Position the supplied template(s) over the area and carefully cut around the template.

Performing a Test

Selecting test type
The instrument can be used with three different sample heads. It is supplied with the foam pad as standard.
(Abrasion/scratch and felt pad heads are optional extras).

• Foam Pad – used for rubproofness testing for BS3110.
• Abrasion Scratch Test – a more aggressive test, useful for assessing through cure of UV coatings or high abrasion transit testing.
• Felt Pad – used to test the water, detergent, solvent or fat resistance of inks and coatings.

Changing the sample head

• Remove any weights and lift the weight platform and turn the handle so that the head is raised (fig 4).
• Pull down on the red sample head to remove (it is held in place by magnets, fig 5).
• Replace with the required version (fig 6).

Rubproofness Testing to BS3110
Ensure that foam is selected in the test menu and the corresponding sample head is fitted.

Test Options

• Face to face – Select an area from the printed material and cut a small and large sample using the sample cutter.
• Face to reference substrate – The large sample should be taken from a sheet of high quality white reference material.
  The smaller sample is taken from the printed material.

Sample Positioning

• Remove the weights from the weight platform and turn the handle to put the instrument into the up position (fig 8).

• Remove the sample clamping ring from around the bottom platen.
• Place the large cut printed sample on the bottom platen and replace the clamping ring (fig 9).
• Place the small test sample underneath the foam head with the side to be tested face down and in contact with the large sample (fig 10).
• Lower the sample head using the handle, adjusting the sample so that when fully lowered, the printed sample is exactly covered by the foam pad (fig 11).
• Add required test weights to the weight platform.
• Run Test (see Running a test).

Abrasion Testing
Ensure that scratch is selected in the test menu and the corresponding sample head is fitted.

Sample Positioning

• Remove the weights from the weight platform and turn the handle to put the instrument into the up position (fig 8).
• Remove the clamping ring from around the bottom platen.
• Place the large cut printed sample on the bottom platen and replace the clamping ring (fig 9).
• Lower the abrasion head into contact with the sample using the instrument handle.
• Apply required test weights to the weight platform.
• Run Test (see Running a test).

Wet Rub Testing
Ensure that felt is selected in the test menu and the corresponding sample head is fitted.

Sample Positioning

• Remove the weights from the weight platform and turn the handle to put the instrument into the up position (fig 8).
• Remove the clamping ring from around the bottom platen.
• Place the large cut printed sample on the bottom platen and replace the clamping ring (fig 9).
• Remove the upper measuring head from the instrument (figs 4-6).
• Soak the felt pad head in the required solvent or dose directly onto the felt pad (max dosage 10ml). Do not apply any liquid directly to the sample under test.
• Lower the solvent head into contact with the sample using the instrument handle.
• Apply required test weights to the weight platform.
• Run Test (see Running a test).

The test can be paused and resumed at any point allowing the reapplication of the liquid. To do this press pause, remove weights, lift handle, remove test head and repeat step 4.

Selecting test revolutions

1. To set the number of revolutions, press the Rev’s button (fig 12) and input the amount of revolutions required (fig13).

Running a test

• Press the on-screen start button (fig 14 )
• Use the touch screen or buttons to pause and restart the test.

See ‘Test Type’ for information on selecting the appropriate test.

Turning on/off the fan
The instrument has a fan to remove paper fibers and debris which act as abrasive agents – not usually required for wet rub resistance test.

• To switch on/off click the button on the test set up menu.

Replacing the pad
After every test, the abrasive or felt pad should be checked for damage or excessive coating built up and replaced if necessary.
The standard foam pads should both be inspected prior to testing. Damaged pads can lead to uneven pressure distribution across the sample, resulting in incorrect results.

• Peel the old pad off the head, ensuring all adhesive residue is removed.
• Ensure the head is dry and free from contaminants.
• Remove the backing material from the replacement pad and stick in place.

Test Results

Evaluation of test results
Pass/fail of each test is determined visually or by further analysis by using a densitometer, glossmeter or spectrophotometer.
