Determining Cleanliness – A Look Into Our Test Lab

Not all cleanliness requirements are equal. Various parts in different industries require different cleanliness levels to optimize product performance and, in many instances, to meet safety standards. For example, removing chips and oils from automotive parts is different than cleaning and sanitizing filling components for pharmaceutical products. The latter requires a higher level of cleanliness.

Why Test?

There are many different types of cleaning systems to help meet these individual needs. Thus, it is imperative to choose the appropriate machine to suit the particular application and comply with any industry regulations.

How do you know if the machine will perform to your cleanliness requirements, though? The answer is to perform a parts cleaning test on the items in question prior to manufacturing. Before testing, determine what type of part needs cleaning and what contaminants need removal. You also need to know how the end-user will utilize the part.

The goal of testing is to simulate the actual cleaning process to determine its efficacy. The customer is then assured that the machine will perform as needed and deliver the expected cleaning results. With this in mind, the manufacturer designs and builds a machine specifically for the customer’s particular parts and cleaning process. This process saves the customer time and money.

Testing Methods

Just as there are different types of parts and cleaning requirements, different tests determine part cleanliness. Various testing methods include:

  • Gravimetric testing relies on a final determination of weight as a means of quantifying a particulate substance whose components are being measured.
  • Microscopic analysis is observation through a microscope to determine the number, size, and quantity of the particles. Particles photographed through the microscope are measured for reporting.
  • Dyne testing is a standard method of assessing the cleanliness of a material’s surface by using a dyne’s fluid. Dyne testing determines the surface energy and measures the surface tension of a liquid.
  • Blacklight testing uses UVA light to see contaminants such as oils, cutting fluids, bacteria, and mold that are not visible otherwise.
  • Water break testing is a simple method that uses DI water to verify surface part cleanliness. Water beads on a surface that contains oily residues; if the water does not bead then the surface is free of contaminants.
