 INTRODUCTION
HiTEC® 523 is a zinc-based hydraulic additive package, designed to meet the
performance requirements of the latest Parker specification, including the T6H20C
hybrid pump test.
At a dosage of 0.6 % wt. in suitable Group I base stocks HiTEC® 523 has
demonstrated the following performance features:

• Parker HF-0, HF-1, HF-2 approval based on performance in the T6H20C

hybrid pump test

• Excellent wear protection, as shown in the ISO 20763 vane pump test

• FZG A/8.3/90 load stage 10 pass

• Filterability in the presence of water

• Protection of yellow metals in the presence of water

• Robust oxidation, rust and corrosion protection

• Meets the requirements of DIN 51524 part II (April 2006)

• Approved against Cincinnati Machine P-68, P-69, and P-70 specifications

HiTEC® 523F delivers the same performance as HiTEC® 523 but contains a non-
silicone based antifoam. At a treat rate of 0.6 % wt. HiTEC® 523F delivers 75 ppm
of anti-foam to the finished fluid.

This report contains a summary of work carried out during the evaluation of HiTEC®

523 against the Hydraulic Specification DIN 51524 Part II for LPC. The current DIN
51524 part II specification was published in April 2006 and outlines DIN's
requirements for a HLP type oil. Basic viscometrics, foam control and air release
testing was also conducted on a formulation using HiTEC® 523F.

Additional testing was also carried out to evaluate the fluid against Public Power
Corporation (PPC) requirements.

MOH BASE STOCKS

The following describes the blends formulated for testing against DIN 51524 part II
(April 2006). HI 028333.40 is formulated with HiTEC® 523 and a top treat of a non-
silicone based antifoam whilst HI 028333.41 is formulated with HiTEC® 523F which
contains antifoam so does not require top treating. Both formulations contain a
polymethacrylate based pour point depressant and Group I MOH base stocks.

pump test replaced the ASTM D2882 vane pump test in 2004. The ISO 20763 vane pump test is equivalent to the ASTM
D7043 vane pump test with the exception of test duration and pump speed. The ISO 20763 vane pump test runs for 250 hours
at a speed of 1460 rpm whilst the ASTM D7043 vane pump test runs for 100 hours at a pump speed of 1200 rpm. Fluids that
show acceptable performance in the ISO 20763 vane pump test would be expected to show acceptable performance in the
less severe ASTM D7043 vane pump test.

SUMMARY OF RESULTS FOR TESTING OF HiTEC® 523 @ 0.6
% WT. IN GROUP I MOH BASE STOCKS AGAINST DIN 51524
PART II (APRIL 2006)
SPECIFICATION

The data compiled for HiTEC® 523 @ 0.6 % wt. in MOH ISO 46 VG base stocks meets or
exceeds all of the requirements of the DIN 51524 part II specification.

A formulation utilising HiTEC® 523F has been tested for foam control and air release and has
demonstrated equivalent or improved performance in both parameters. Performance in other
tests is not anticipated to be affected utilising HiTEC® 523F instead of HiTEC® 523 with a top
treat of a non-silicone based antifoam.

HiTEC® 523 @ 0.6 % wt. in MOH ISO 46 VG base stocks was also tested against the
additional requirements of the Public Power Corporation (PPC). The testing demonstrated that
the formulation met the FZG, vane pump test and 4-ball wear requirements but did not meet
the Life TOST requirement.
