Preventative Maintenance Through Smart Condition Monitoring

 

The condition of the fluid in your system is crucial for optimum machine performance. HYDAC is committed to assisting you in identifying the causes of any problems in your system through fluid analysis. The team in our UK Laboratory will assist you with any concerns raised from your analysis, and advise of any measures you can put in place to best care for your systems and fluid.

Laboratory Services

The following tests are our most commonly performed, but we are not limited to these. To obtain a digital list, available for printing, please see our "Laboratory Services Manual" in the Downloads section of this page.

Microscopic Contamination Analysis

Associated Standard: ISO 4406

Commonly referred to as a “Patch Test”; we use the solid particles within your fluid sample, or separate residue (if taken from a used filter etc.), and analyse these under the microscope. This allows us to identify the type of contamination present and verify any particle count results. If required, these solid particles or residues can be further analysed using an SEM (scanning electron microscope) to determine their exact composition.

Particle Distribution Measurement

Standard: ISO 11500 Associated Standard: ISO 4406

Also known as a “Particle Count”; an optical particle counter is used to determine the size and quantity of particles in your sample of oil. The size, composition and quantity of such particles can have a considerable effect on the wear and tear of the hydraulic components within your systems.

Water Content Analysis

Standard: ASTM D6304

A high water content in oil can be very damaging to hydraulic machinery and can contribute to oil ageing, both of which can be very costly to fix. This analysis uses the Karl Fischer method to provide an absolute water content, in PPM, of the solution being tested. We will even recommend safe operating values, as long as we are provided with the fluid type and application.

Conductivity Test

Standard: ASTM D2624

The conductivity of mineral-based oils has decreased over the years, as oil manufacturers have refined their products to provide greater performance and to adhere to environmental restrictions. Despite these benefits, the decrease in conductivity has left some systems vulnerable to electrostatic discharge. This effect can result in sparking at filter elements and other areas of the system, which not only greatly reduces filtration efficiencies but also contributes to oil ageing. This test calculates the value, in pS/m, of the conductivity of your oil; we can then recommend whether there is a risk of electrostatic discharge occurring.

ICP Analysis

ICP stands for Inductively Coupled Plasma, and this analysis allows us to identify the quantity, in ppm, of individual elements within a fluid. This is a helpful way of determining contamination causes, whether it’s from wear metals or from another source. It also enables identification of additive levels in the fluid and the subsequent trends, allowing us to observe the rate of depletion and recommend oil changes.

Viscosity Analysis

Performed at 40°C and 100°C, it is very important to keep track of the viscosity of your oil as it’s generally regarded as the most fundamentally important property of lubricants. Increased viscosities will cause excess heat in the system and accelerate the fluid ageing process. A reduced viscosity may mean your components are not being protected, leading to excess wear. If the viscosity of a fluid is found to have changed, then further investigation into the reasons for this change will be necessary, as the oil may not be performing to its required standard.

MPC Test

MPC stands for membrane patch colorimetry, and this tracks the amount of insoluble particles present in the oil so you can act before harmful varnish and sludge build-up occurs on critical components. This is particularly relevant in mineral-based oils that have been subject to high heat or water ingress, as these factors accelerate the rate of oil ageing and varnish production.

TAN Analysis

A potentiometric titrator is used to find the levels of acidity in your oil sample. Acids found in oil are an indication of oil ageing as a result of oxidation; this can lead to corrosion and damaging deposits in the system. This procedure can be used to determine relative changes to the acid levels in your system. This is particularly relevant in ester-based fluids as the rate of acid production is relative to the rate of oil ageing.

FAQ's

Q: How long do the results take to come through?

A: This varies depending on the complexity of the tests and the number of samples. For one or two samples requiring a "Basic Oil Analysis", the results are usually provided within 2 working days of receipt of the sample.

Q: What is an acceptable water content/ISO code/TAN etc. for my oil?

A: Again, this is a very situational question, which is why we offer "Sampling Records". When fully filled in, these sheets give us the information necessary to provide an accurate and experienced assessment of the results.

Q: Do you provide training courses?

A: Yes, we do provide training courses, our most popular of which encompasses the basics of "Contamination Control". We are able to tailor this to your industry so your staff get the most from it. Please enquire for further details.
