LAB TEST LIST & EXPLANATIONS

Here’s an A-Z list of everything WestChem’s in-house team does in the lab and why…

BLISTER ANALYSIS – ASTM D714 – Determines the degree of blistering of a painted specimen.

BOIL TEST – Refer to Cross Hatch Dry Adhesion. Except, the test specimen is immersed in 100C boiling RO/DI Water for 20 minutes.

CAULKING ANALYSIS – Determine the effectiveness of varying caulking and sealants.

CHEMICAL BATH COMPATIBILITY – This test is to determine if the addition of another chemical of the same function could be added into the current one without any repercussions such as splitting or flocculation.

CHEMICAL BATH/PRODUCT COMPATIBILITY – Determine the compatibility of two comparative chemical concentrates or baths.

CLEANING ANALYSIS (VIS) – Determine the chemistry and parameters that will remove surface contaminants (oils, soils, debris etc.) from a part/panel. Water-break-free analysis completed.

COMPARE CLEANING ANALYSIS (VIS) – A test method where a variety of chemistries are used, at varying parameters to clean panels/parts. The panels/parts are then evaluated based on how much of the surface is water-break free, and which chemistry/parameters worked best.

COMPETITOR PRODUCT COMPARE – A test method where competitor chemistries are used to compare effectiveness against various WestChem products, at varying parameters.  CONCENTRATION OIL TESTING (REFRACT/OIL SPLIT) – Determine the refractive index for each concentration using a refractometer. Or utilizing a strong acid split test to determine the concentration of oil/water emulsion.

CONVERSION COATING ANALYSIS (VIS) – Determines the uniformity and effectiveness of the conversion coating on a given substrate.

COOLANT COMPATIBILITY – A test method used to determine whether a competitor coolant is compatible with a WestChem coolant at varying concentrations. Mixtures are analyzed for any splitting, flocculation or adverse reactions. Compatible coolants can be directly added together without dumping a sump, and re-charging with a new product.

COOLANT CORROSION TESTING – ASTM D4627 Cast Iron Chip Test – Determines corrosion characteristics of a new / used machine coolant bath.

CORROSION PREVENTATIVE OR RUST INHIBITING TESTING – Determine corrosion/rust inhibiting abilities of a given product at various parameters.  CROSS HATCH DRY ADHESION – ASTM D 3359 is a test method for evaluating adhesion by knife and contains a rating system table to evaluate the findings. The panel is scored and ASTM-approved adhesive tape is applied. The tape is ripped off quickly and the cross hatch is evaluated on how much paint was removed.

CROSS HATCH WET ADHESION – Refer to Cross Hatch Dry Adhesion. Except, the test specimen is immersed in room temperature RO/DI Water for 24 hours.

DEFOAMING ANALYSIS – Determine the effectiveness of varying defoamer chemistries in varying conditions.

DENSITY ANALYSIS – A measure of how compact the mass in a substance or object is. The density of an object or substance can be calculated from this equation: density in kilograms per meter cubed is equal to mass in kilograms, divided by volume in meters cubed. Or in other words, density is mass spread out over a volume. DESCALING ANALYSIS – Determining the effectiveness of various descaling products on specific scale deposits from customer equipment/tanks.

DIGITAL IMAGING – General imaging of panels/parts or specimens.

EQUIPMENT, MATERIAL & SEAL COMPATIBILITY – Determine the compatibility of a chemical with a specific material, seal or equipment.

FOAM TEST – Analysis of surfactant-containing liquids regarding foam creation, foam stability and foam structure.

FREEZE / THAW ANALYSIS – Determine if a chemical concentrate or bath can be frozen and thawed and will continue to operate as normal.

GENERAL BATH AND PANEL/PART TESTING – Comparing/analyzing the effectiveness of various chemical baths, at varying parameters, using various metal substrates.

IMPACT TEST – to determine the impact resistance or toughness of materials by calculating the amount of energy absorbed during fracture.

IRON PHOSPHATE COATING WEIGHT – This analysis is used to determine the deposit weight of an iron phosphate conversion coating. The Weigh-Strip-Weigh method is utilized using a precision scale to provide accurate coating weight measurements.

MICROSCOPIC IMAGING – Up to 50X zoom to determine the presence of items that are not visible to the naked eye.

MULTISTAGE BATH PROCESSING – Using multiple chemistries on one panel/part to simulate how a customer would run their production line with these chemicals in use. EG: Acid Cleaner for scale, Alkaline cleaner for degreasing, conversion coating, and final sealer.

NEUTRALIZING ANALYSIS – Determine the type and amount of chemistry needed to neutralize a given bath or chemical concentrate (Acidic or Basic).

OIL SPLIT (BATH LIFE) TEST – Performed to check how contaminated/saturated a chemical bath is with oil.

OUTSOURCED LAB WORK NEEDED – Specialty analysis and projects that are outsourced at an additional cost.

PAINT CURE ANALYSIS (MEK) – MEK Rub test to determine the cure effectiveness of a powder-coated substrate.

PAINT FAILURE ANALYSIS – Various laboratory methods to determine the root cause of a paint failure. Typically, a combination of several methods. E.g. Microscopic Imaging, evaluation of back of paint.

PAINT MIL THICKNESS – Determines the thickness of a paint coating. Typically, in Mil or Microns.

PAINT OR OTHER STRIPPING – Determine effectiveness and timeframe for stripping a desired coating, with a desired product.

PAINT STRIP – Removes coated paint from part/panel. Determines the ideal product and parameters for the specific paint.

PANEL SAWING / CUTTING – Ability to cut metal to perform lab work. It is ideal to have customers perform any cutting before sending to the WestChem lab.

PANEL SAWING TITRATION – This is a chemical qualitative analysis technique used to calculate the concentration of a given analyte in a mixture.

PENCIL HARDNESS TEST – ASTM D3363 – Determines the film hardness by pencil test. Can be an indicator of paint undercure or overcure.

PH TEST – determines the potential of hydrogen of a chemical or bath.

POUR POINT ANALYSIS – the lowest temperature at which an oil/chemistry is observed to flow by gravity in a specified lab test.

RUST GRADE ANALYSIS – ASTM D610 – Determines the degree of blistering of painted specimens.

RUST/SCALE REMOVE TEST – Determine the chemical effectiveness for removing varying degrees of rust and scale from a metal panel/part.

SALT SPRAY – Our salt spray corrosion testing machine follows the ASTM method B-117. Panels are scribed (with optional taping of edges) and placed inside to undergo an accelerated corrosion process. After a specified hour interval, parts/panels are removed and evaluated under ASTM D1654/D7087.

SCRATCH TEST – Adhesion test method for a painted specimen. Surface is aggressively scratched to determine the adhesion of the paint to the substrate.

SMELL/ODOUR ANALYSIS – Qualitative comparative analysis on smells/odours of chemical baths and/or concentrates.

SOLVENT CLEANING ANALYSIS – Utilizes a variety of solvents to clean a variety of surfaces.

SPECIALTY CLEANING ANALYSIS – Utilizing various cleaning chemicals to remove unconventional items from metal, equipment or other. Example: removing a specific sealant from a floor.

STABILITY ANALYSIS – Determines the stability of a given chemical concentrate/bath in a specific environment.

TDS/CONDUCTIVITY – Total dissolved solids (TDS) or Conductivity (us/cm3) are the amount of organic and inorganic materials, such as metals, minerals, salts, and ions, dissolved in a particular volume of water, or mixed chemical bath.

TIMKIN LUBRICITY ANALYSIS – The Timken Method (ASTM D2509) is one of several different tests to evaluate the load carrying capability of lubricants.

TITRATION CURVE – Determining the titration values of a chemistry using a given Test Solution (0.1 – 1N) in a known chemical bath concertation. Develops a titration factor to convert between ‘MLS titrated and % by volume.

VISCOSITY ANALYSIS – shear stress (force) is mechanically applied to the fluid, and the rate the fluid layer moves over a stationary material is measured.

ZINC PHOSPHATING PANELS – Use a lab bath to deposit a zinc phosphate conversion coating on panels/parts.

ZINC/MANGANESE PHOSPHATE COATING WEIGHT– This analysis is used to determine the deposit weight of a zinc phosphate conversion coating. The Weigh-Strip-Weigh method is utilized using a precision scale to provide accurate coating weight measurements.
