Quality control in the field: Gazpromneft Hydraulic HLP 46 confirmed within specification
Confidence in an industrial lubricant is built on data. FEOTECH works with customers and distribution partners to coordinate field sampling and laboratory testing of both fresh product and in-service oil. One independent check of fresh Gazpromneft Hydraulic HLP 46 sampled from a 205-litre drum found every tested parameter within normal limits and consistent with the manufacturer's specification.
Quality control starts before oil enters the system
The sample was drawn directly from commercial packaging at the storage location using dedicated extraction equipment. This helps verify the condition of the delivered product before filling and establishes a documented starting point for later monitoring.
FEOTECH's approach goes beyond manufacturer documentation. Together with customers and distributors, our team coordinates fresh-oil checks, field trials and used-oil analysis according to the application and the equipment risk involved.
Field sampling in practice
Independent laboratory test results
In July 2025, a fresh sample of Gazpromneft Hydraulic HLP 46 was tested by an independent laboratory in Indonesia. FEOTECH's technical summary of the measurements shows the principal parameters in normal condition and consistent with the product data sheet.
Taken together, the results do not indicate water ingress, significant contamination or a viscosity deviation in the sample tested. Clean filling procedures and closed, protected storage remain essential to preserve that condition until the oil enters the system.
Key fresh-oil sample results
FEOTECH summary of independent laboratory measurements for a Gazpromneft Hydraulic HLP 46 sample from a 205-litre drum.
Within the ISO VG 46 range of 41.4-50.6 cSt
Listed typical product value: 6.8 cSt
Below the listed typical value of 0.6 mg KOH/g
No indication of significant water ingress in the sample
Above the listed typical value of 227 °C
No foam tendency or stability in all three sequences
Fresh-product baseline; system targets depend on OEM and filtration
Supporting property, not a stand-alone pass/fail limit
This is a FEOTECH technical summary, not a reproduction of the laboratory report. The data apply only to the sample tested and do not constitute batch certification, a guarantee for all product, or laboratory endorsement. Final cleanliness targets must follow the relevant OEM and system-filtration requirements.
What the results mean for users
Kinematic viscosity at 40 °C measured 47.56 cSt, within the ISO VG 46 range of 41.4-50.6 cSt. Viscosity at 100 °C was 6.971 cSt, also close to the listed typical value of 6.8 cSt, confirming consistency with the declared grade.
A TAN of 0.41 mg KOH/g, water content of 84 ppm, a 234 °C flash point and 0/0 foaming results in all three sequences support the technical assessment that the fresh-oil sample was in good condition. The ISO 4406 cleanliness code of 18/16/11 provides a documented baseline; final cleanliness targets should still follow the relevant OEM and system-filtration requirements.
Traceable quality, not a one-off certificate
A single test result applies only to the sample tested and does not replace batch-level quality control. Its value is in a repeatable process: take a representative sample, use relevant ASTM and ISO methods, compare the results with manufacturer data, and retain a baseline for future technical decisions.
As the official importer and authorized distributor of Gazpromneft Lubricants in Indonesia, FEOTECH connects the official supply route, product documentation, technical support and field verification so customers can make evidence-based decisions.
Commitment to quality“For FEOTECH, quality is more than a number in a product document. Customer confidence is built through an official supply route, traceable documentation and technical verification in the field. By coordinating sampling and independent testing, we help customers understand the condition of the product that will actually enter their equipment.”
B2B customer support“For industrial customers, quality control starts before the lubricant is filled into the system. FEOTECH's B2B team coordinates packaging checks, sampling and technical review of the results so that customers have a documented baseline and clear handling recommendations.”
