A look into the S100 test laboratory

The MOTORRAD home visit gives you a glimpse behind the scenes of companies in the motorcycle industry. This time we are for you in the laboratories of Dr. Wack and show the procedures with which the care line S100 is tested.

Dr. Wack is one of the leading manufacturers of products for vehicle care. 1975 by Dr. Founded by Oskar K. Wack, the Ingolstadt company is still in family hands. The products in the motorcycle sector are carried under the sub-brand S100, best known for the motorcycle cleaner, as well as the white chain spray and the transparent Dry Lube.

Company foundation: 1975
Employees worldwide: Approx. 300
Managing Director: Dr. Harald Wack, Ralph Hoeckle, Stefan Wind
Corporate headquarters: Ingolstadt

For the MOTORRAD home visit we were allowed to take a look behind the scenes of Dr. Throw it up, take a look around the company’s own laboratories. There, Hartmut Hauber, the head of application technology, regularly checks the quality and effectiveness of the white chain spray, which has often performed well in the MOTORRAD comparison test. We have put together for you which procedures are carried out there and how the various criteria are checked.

Hartmut Hauber explains the different setups of the tests.

Test procedure for the S100 white chain spray

Dr. With the white chain spray, Wack, or S100, would like to meet four requirements that they themselves place on good chain lubrication: wear protection, creep ability, corrosion protection and adhesion. These properties are regularly tested in the laboratories – we took a closer look at the whole thing.

1. Wear measurement

A test stand from the University of Mannheim simulates the movements of the chain by means of friction on a treated piece of metal, making the wear measurable. To do this, a metal roller in a tub is moistened with the lubricant; after ten minutes of drying time, it hits a small metal cylinder while rotating. In addition, different parameters such as friction and temperature are constantly measured. Depending on the manufacturer – competing products also run over the roller here – a more or less worn area arises on the test body. This furrow is then measured under a microscope. This creates a comparable and reproducible value for wear protection.

2. Corrosion test

For this purpose, degreased metal plates are first treated with the chain spray and dried for one hour. Then they bathe in a five percent saline solution, which is constantly stirred gently. After 24 hours they are finally wiped off and the size of the discolored, attacked area is measured. In this way it can be determined how well an appropriate agent – in this case the white chain spray – protects against corrosion, i.e. rusting of the chain.

Here is the setup for testing the corrosion protection.

3. Creep behavior

To measure the creep behavior, first two cleaned glass plates are placed on top of one another so that the lower one peeks out a little. The chain spray is sprayed onto this resulting edge. It now begins to crawl between the plates over a period of 15 minutes. The method used to subsequently compare these areas is surprising: a graph paper is placed on top and the edge of the agent that has flowed in is traced. The creep behavior can now be measured and evaluated depending on the area.

4. Liability

The adhesion concerns on the one hand the dirt adhesion and also the throwing off of the agent from the chain. The latter is measured by spreading the agent evenly on a round metal plate and then rotating it. Around it is a collecting container that is weighed before and after. In this way, the mass of the agent that was thrown off can be determined.

The adhesion of dirt is also assessed using a scale. A metal plate is treated with the spray and positioned upright to dry and run off. It is then pressed into a bowl of sand that is on a scale. If grains of sand stick to the piece of metal, the difference in the weight of sand in the container can be used to determine the amount of dirt that has stuck.

Further test procedures for S100 products

1. Impregnation spray

To measure the effectiveness of the impregnation spray, half of a cleaned cloth is treated with the agent. After an hour of drying time, water is poured over it. It quickly becomes apparent that the untreated side is completely soaked with water. In the best case scenario, water rolls off the treated side completely. After one run, the visible water residues are rated using a scale with comparative images. If necessary, the sprinkling is repeated up to ten times, with an evaluation being made after each sprinkling.

This is how an impregnation spray is tested: let the agent take effect, clamp in, water.

2. Laundry detergent

The detergent for motorcycle clothing is also regularly tested. For this purpose, squares of fabric with various impurities – for example blood, oil, red wine, everything standardized and bought in this form – are washed with the agent. A measuring device then determines the intensity of the residual discoloration, or more precisely the degree of whiteness of the spots. This means that precise values ​​can also be compared here.

3. Polish and wax

Not everything that shines shines the same. With most polishes you actually see a direct before-and-after difference in the surface. But there is also a measuring device to measure exactly how much the gloss has improved. This measures what is known as the haze of gloss, i.e. the proportion of scattered light in the reflected light, as well as the gloss, which shows how much light is reflected from the surface.

A wax treatment usually aims to visually enhance surfaces and protect them from the effects of the weather. So water should roll off as well as possible. This is measured using a contact angle measuring device. A tiny, defined drop of water drips onto the surface and transfers the image to the computer with an integrated microscope camera. The angle at which the edge of the drop meets the wax-treated surface is now measured. If it is very steep, the water is effectively repelled. If the edge is flat, the effect is less.

Conclusion

Dr. Wack attaches great importance to testing its products intensively and developing them further. The large test laboratories and the noticeable dedication of application engineer Hartmut Hauber clearly showed the great importance that our own recipes have here. Around 30 people are employed in in-house research. No matter what they come up with: We will test it for you.
