Chip resistance test is used to assess the resistance of paints and similar
coatings against the impact of a chilled cast granulate or stone made according
to standard as simulated rock impact.
The stone chip resistance of the coating is tested by many small sharp-edged
striking bodies or stones, which hit in rapid succession and largely
independently of each other. The bombardment material is a defined chilled
granulate or stones, which is shot with compressed air at a fixed angle to the
coating. The extent of the damage also depends on the working pressure, the
mass of the bombardment material, the firing time and the construction of the
tester. Loosely attached coating material is removed with an adhesive tape. The
degree of damage is assessed by comparison with images.

TECHNICAL CLEANLINESS
The basis for the methods for determining the technical cleanliness are the
volumes VDA 19 and ISO 16232, parts 1-10.
- VDA 19: 2004: Testing of technical cleanliness - Particle contamination of
functionally relevant automotive parts
- VDA 19-2: 2010: Technical cleanliness in the assembly
- ISO 16232, Parts 1-10: Road vehicles - Cleanliness of components for fluid
systems
The cleanliness test is basically a sampling test. A test of this property by means
of testing machines is not possible.
To achieve a requirement for the technical cleanliness of components, a holistic
consideration of the processes, even after the added value of the individual
product, is essential. These include, for example, processes such as sorting,
packaging, transport and assembly. These are to be agreed with regard to the
requirements for technical cleanliness between customer and supplier.
The technical cleanliness test is an indirect test requiring a sampling step. For
the relevant surfaces of critical parts are often located in the interior of pipes,
ducts, housings, tanks, pumps, valves or similar components in which fluids are
often conveyed, which can transport particles to sensitive areas of systems.
These inner surfaces are usually not accessible for direct tactile or optical
inspection. In addition, most of the surfaces are not suitable for optical
inspection due to material, roughness, and lack of contrast with the particle
contaminants.
For this reason, extractions are first necessary for analyzes of technical
cleanliness. In the first step, the particles are cleaned off the test part via a
laboratory cleaning step. Subsequently, the filtration of the complete extraction
medium and the separation of the particles extracted from the component are
carried out on an analysis filter, which is then the actual analysis - usually under
the microscope - is supplied.

The salt spray tests are particularly useful for detecting weak spots such as pores
and other damage, in certain metallic coatings and organic coatings, as well as
anodic oxide layers and conversion layers.
The neutral salt spray test applies to:
metals and their alloys;
metal coatings (anodic or cathodic effective);
conversion layers;
anodic oxide layers;
organic coatings on metallic materials.
The acetic acid salt spray test is particularly useful for testing decorative coatings of
copper + nickel + chromium or nickel + chromium. It is also suitable for testing
anodic layers on aluminum.
The copper-accelerated acetic acid salt spray test is useful for testing decorative
coatings of copper + nickel + chromium or nickel + chromium. It is also suitable for
testing anodic coatings on aluminum.
All salt spray techniques are suitable for comparing whether the quality of a
metallic material, with or without corrosion protection, is maintained.
Standard: DIN EN ISO 9227: 2006
Neutral salt spray test (NSS test): 5% NaCl (sodium chloride solution) - pH 6.5-7.2;
distilled or deionized water with a conductivity of at most 20 S / cm
Acetic acid salt spray test (AASS test): Addition of glacial acetic acid to the saline
solution (5% NaCl) - pH: 3.1-3.3
Copper accelerated acetic acid salt spray test (CASS test): Dissolve cupric chloride
dihydrate (CuCl2 2 H2O) in the saline (5% NaCl) to give a concentration of (0.26 ±

moisture - Method for stressing samples in condensation water limits:
Condensed water glands we are referred to as follows:
Test climate CH Condensed water constant climate
(Condensation atmosphere with constant humidity)
AHT condensate change climate with change of air humidity and temperature
(Condensation climate with alternating humidity and air temperature)
AT Condensation change climate with change of air temperature
(Condensation climate with alternating air temperature)
Condensation test climates allow the condensation of air humidity on sample
body surfaces whose temperatures are smaller than those of the saturated test
chamber air due to radiation onto the chamber walls or through sample body
cooling. The air temperature of the test chamber during the condensation
process described in this part of ISO 6270 is 40 ° C.

Plastics consist mainly of macromolecules and are divided into three groups:
elastomers, duroplasts and thermoplastics. The tests such as formability,
hardness, elasticity, breaking strength, temperature, heat resistance and
chemical resistance are performed on plastics.
The amount of glass fiber content and filler plays an important role in plastics.
The determination of the glass fiber content is made by ashing.

Washability (SAE J2260 BMW PR563) or determination of extractable
constituents from fuels in contact with fuel:
The fuel lines are completely filled with the test fluid. Air pockets should be
avoided. The fuel lines should be pressure sealed with tube caps (such as
Swagelok). An interaction of the tube caps with the test fluid is, e.g. The filled fuel
lines must be stored in an explosion-proof forced air oven at (60 ± 3) ° C for 96
hours. After storage, store the fuel lines at room temperature (23 ± 2 ° C) and
allow to cool. The fuel lines are to be emptied immediately after cooling to room
temperature (23 ± 2 ° C) but after a maximum of 60 minutes in a closable glass
bottle. The fuel lines should be rinsed with exactly 20 ml test fluid. For this
purpose, fill the rinsing liquid into the pipe and let it flow back and forth several
times. The amount of rinsing must also be emptied into the glass bottle. Store the
sealed glass bottle for 24 h at room temperature (23 ± 2 ° C).

COOLANTS / LUBRICANTS
Coolants TRGS 611
DIN 51385
Cooling lubricants are lubricants that are used for lubrication or for cooling /
lubricating during machining and during forming of materials, in particular of
metals.
quenching
Water-miscible quench media can be run on any water. Certain water qualities
are not necessary for quenching effect. However, waters with high water
hardness, high chloride and sulfate contents have an unfavorable effect, as they
accumulate during the long-term operation of the plant.
High water hardness introduces large amounts of salt into the solution, which can
leave deposits on parts and containers. A high chloride and sulphate content have
a negative effect on the corrosion protection.
Water can contain microbes. This permanent contamination with
microorganisms may damage the solution. The mixing water should have drinking
water quality (maximum germ counts according to the Drinking Water Ordinance:
100KBE / ml (CFU = colony-forming units), pathogens must not be present.
Demineralized water, e.g., ion exchange water, is also not germ-free and is often
even more contaminated than drinking water.
If drinking water is supplied for mixing or post-dosing via pipe or hose lines, the
formation of biofilms, which can lead to contamination, must also be expected
within the piping systems. Therefore, the "stale" water should be drained
beforehand.
