Automotive Cleanroom Testing

Automotive Cleanroom Testing

Since the early invention of the assembly line, the automotive industry has made incredible strides in their manufacturing processes. Indeed, a wide range of attention is given to mass defects, or preventing them. Like other industries the need for manufacturing auto components inside cleanrooms has become a key factor in the automotive industry. .

In Automotive Cleanrooms factors like pressure, temperature and humidity are just as important to other rooms designed in the cleanroom classification range of ISO 7 and ISO 8. The defects that can (and do) occur in the automotive manufacturing industry are vast, including costly errors like glass coatings, electrical components, and painting to the bodywork.

We also need to test the flow of the air to ensure that it is moving from clean to less clean areas, minimising the movement of any contaminated air into your clean area, and also to ensure there are no areas of the room with high concentrations of pollutants.

In order to carry out these tests, for every clean room we are working in, we will measure and check:

  1. Air movement control – Studying the movement of the air within your clean room we will check that there is sufficient air movement to dilute or remove pollutants, preventing any contamination build-up.
  1. Temperature, Relative Humidity – We may also need to carry out tests on temperature, relative humidity, and the heating and cooling capabilities of the room, as well as noise, lighting and vibration levels.
  1. Airborne particulate testing – We will carry out measurements to ensure that the concentration of particles and micro-organisms is compliant with the specification set out for your clean room.
  1. Filter installation leak testing – Your ventilation system’s high efficiency particulate air (HEPA) filter, and its housing will be tested with DOP (Dispersed Oil Particulate) to ensure their integrity.
  1. Air supply and extract quantities – If your air supply is unidirectional we will measure and record the air velocity, while for non-unidirectional systems we will measure air supply.
  1. Containment leak testing – We will check the construction of your clean room to ensure that no airborne contamination can occur via leaks from higher pressure work areas adjacent to it.

APT Cleanroom Testing will always try to ensure that you fully understand our process and your results, following any clean room testing or validation service, we will present you with clear, easy to follow cleanroom test reports that can be compiled, quality checked and issued to you while still on site, minimising the down time of your operations.


If you have a clean room that requires a cleanroom testing service then please get in touch with us as soon as possible. We should be able to offer you an expedient solution for all your cleanroom testing and certification. We can also offer maintenance programmes to ensure your cleanroom is in compliance with the corresponding ISO standards.

The Evolution of Cleanrooms

The Evolution of Cleanrooms

Cleanrooms come in all shapes and sizes from small laboratories through to large manufacturing buildings. Cleanrooms are used  for a variety of industries such as pharmaceutical production, scientific research, software engineering and manufacturing and aerospace engineering .

Though the cleanliness standards may have changed throughout the years, their purpose has always remained the same. Cleanrooms will continue to evolve as more and more research is conducted and air filtration mechanics and room envelope construction continues to improve.


Six things you didn’t know about cleanrooms:

  1. More and more food industries are using cleanrooms to manufacture products that rely on high sanitation standards, thus improving the quality of their products.
  2. Cleanrooms are rated by their class, which is dependent on the number of particles found in the room at any given time.
  3. Did you know that a motionless person standing in a cleanroom still emits more than 100,000 particles per minute? That’s why it essential that the correct clothing is worn at all times.
  4. The top four things that you need to wear in a cleanroom should be a cap, cover/apron, mask, and gloves.
  5. NASA relies on cleanrooms to continue growth for the space program as well
  6. There are many different types of contamination that can contribute to product failure and inaccurate testing and results, such as micro-organisms, inorganic materials, and air particles.

A Brief History of Cleanrooms

A Brief History of Cleanrooms

The first cleanroom identified by historian’s dates back to the mid-19th century, where sterilised environments were being used in hospital operating rooms, although not clean by today’s standards they were none-the less clean for their time. Modern cleanrooms were created during World War 2 where they were created to produce and manufacture state of the art weaponry in a clean and sterile environment.

During the war, US and UK industrial manufacturers designed a colossal amount of hardware such as guns, tanks and aeroplanes this contributed to the success of the war by providing the military with weaponry that was needed at each juncture of the war. Often major scientific breakthroughs are made during wartime.

Modern Cleanroom Design 


It is known that the HEPA filters were being used throughout cleanrooms by the early 1950s. Some believe that cleanrooms date back to World War I when there was a need to segregate the work area to reduce cross-contamination between manufacturing areas; however no exact date can be found for the introduction of the first cleanroom.

Regardless of when they were introduced into the manufacturing world, contamination was one of the main problems and cleanrooms were the solution. Continually growing and constantly changing for the betterment of projects, research, and manufacturing, cleanrooms as we know them today are recognised for their low levels of pollutants and contaminants allowing for incredible scientific breakthroughs such as Nano Technology etc.

Prior to the creation of modern cleanrooms, early cleanrooms had contamination due to particles and unpredictable airflow throughout the room.  With this in mind cleanrooms were created allowing for a constant, high-filtration airflow, which is what is used throughout cleanroom design and construction today.
