Focus on Viscosity - Analytical Instrumentation What methods are used for


lubricant quality testing? Asset protection and condition monitoring solutions provider Bently Nevada describes lubricants as the “lifeblood of your machines”. This statement is spot-on and underscores the critical role lubricants play in maintaining effi ciency, minimising unplanned downtime and maximising profi ts across a myriad of sectors and industries.


With such an important role to play, it’s no surprise lubricants are subject to in-depth quality testing. ASTM International, a global standards organisation used across a wide range of industries, publishes some of the most widely used and well-respected testing methods.


The role of ASTM International


Viscosity is one of the most important parameters used to determine lubricant quality. The ASTM D2422-97(2018) Standard Classifi cation of Industrial Fluid Lubricants by Viscosity System is considered a benchmark when testing for this parameter. It can be applied to all petroleum-based fl uid lubricants, as well as non-petroleum lubricant products. The method categorises samples into different kinematic viscosity grades ranging from 2 cSt to 3200 cSt (mm2/s).


Methods such as the ASTM D2422-97(2018) are used by lubricant manufacturers to determine viscosity and carry out quality control. ASTM D2422-97(2018) is also used by end users during acceptance testing assays.


Monitoring the quality of in-service lubricants


In addition to quality control and acceptance testing, lubricant assays form the backbone of industrial asset management strategies. For example, the ASTM D7684-11(2020) Standard Guide for Microscopic Characterization of Particles from In-Service Lubricants is used to detect debris and contaminants in circulating lubricants and hydraulic oils. Results allow operators to assess the health of mechanical assets and detect issues such as wear and corrosion before they result in unplanned downtime or catastrophic failure.


A new era of digital testing


Many conventional lubrication oil monitoring tests involve manual sample collection and testing at offsite laboratories. This increases the risk of human error and can lead to delays, which can leave assts vulnerable to issues such as corrosion and wear caused by abrasive particles.


Innovative digital lubrication oil monitoring systems such as VitalyX by Shell and Bently Nevada combine automated sensing technologies, cloud connectivity, data science and edge computing to offer a new era of lubrication oil monitoring. Sensors are used to measure critical parameters in real-time, with advance software systems used to combine the data and generate a in depth overview of lubricant quality and ultimately, asset health.

viscosity measurements Anton Paar’s SVM 1001 and SVM 1001 Simple Fill budget-friendly kinematic viscometers are an entry ticket into the world of digital automatic kinematic viscometry.


Both models come with an unbreakable measuring cell, for a wide variety of samples – without the need for a stopwatch, liquid bath for temperature control, or additional glass capillaries – across a broad viscosity range.


Automatic measurement and calculation of results eliminates errors due to incorrect measurement or manual transcription and calculation. Integrated Peltier temperature control removes the need for a thermostatting bath, bath liquid, or separated thermometer. With a single measuring cell, the SVM 1001 series covers a 0.3 mm²/s to 5 000 mm²/s range – usually requiring 10 or more Ubbelohde-type capillaries.


The kinematic viscometers deliver fully ASTM-compliant results, in both D7042 and D445. In comparison to manual glass capillary viscometers, the SVM 1001 series has 150 % higher throughput while consuming 95 % less energy (50 W instead of 1 000 W) and 75 % less solvent (10 mL instead of 40 mL). This signifi cantly reduces not only operational costs, but also environmental footprint.


SVM 1001 Simple Fill’s unique funnel fi lling system enables direct fi lling of a sample from the sample container, cutting out consumable costs for pipettes or syringes.

The ideal viscometer for oilfi eld and refi ning applications


For More Info, email: email:


One of the huge range of on-line viscometers from Hydramotion was installed directly into the process line at a North American refi nery’s integrated crude topping/vacuum distillation unit. The Hydramotion XL7-152 intrinsically safe viscometer monitors atmospheric tower bottoms at temperatures of up to 365°C/690°F, and the continuous, real-time viscosity data enables engineers to make any immediate adjustments required to keep the pumps turning.


The XL7-152 was chosen because of its unparalleled ease of use, precision and excellent repeatability at the low viscosities involved (less than 50 centipoise). And although the transducer dissipates heat, the unique high temperature design means no special cooling is needed. The XL7 is certifi ed to EEx™ IIC T4 for use in Zone 0 Hazardous Areas (Class 1 Div 1 Group A) which is compliant with the plant environment.


Hastelloy C276 was used for all wetted parts so corrosion would be minimised. The XL7 is supplied with any necessary process fi tting, the probe is an all-welded construction which can be placed in the full liquid fl ow in any orientation, with no need for any ancillary pipework. This makes installation simple, while eliminating discrepancies caused by localised temperature differences or unusual measurement conditions.


The XL7 is a robust, fi eld-hardened instrument that measures any viscosity range at temperatures as high as 400°C+ in any tanks or pipes. The digital read-out unit can be installed up to a kilometre away from the transducer, and because all signals between sensor and safe area are digital, Hydramotion’s EX solution only requires a single safety barrier.


Unaffected by changes in fl ow rate or bubbles/slugs of air or gas, and with no moving parts to wear out or fail, the XL7 is a bolt-on-and-go device requiring no on-site calibration and almost no maintenance.
