Foreword

Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and Cooperatives established under Cap 327, of the Laws of Uganda, as amended. UNBS is mandated to co-ordinate the elaboration of standards and is

(a) a member of International Organisation for Standardisation (ISO) and

(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and

(c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO).

The work of preparing Uganda Standards is carried out through Technical Committees. A Technical Committee is established to deliberate on standards in a given field or area and consists of key stakeholders including government, academia, consumer groups, private sector and other interested parties.

Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the general public for comments. The committee reviews the comments before recommending the draft standards for approval and declaration as Uganda Standards by the National Standards Council.

The committee responsible for this document is Technical Committee UNBS/TC 16, Petroleum, Subcommittee SC 1 Petroleum and Petrochemical

DUS 2159 consists of the following parts, under the general title Hydraulic Lubricating Fluid — Performance Classifications:

Part 2: General

Part 2: Specifications for categories HH, HL, HM, HV and HG

Part 3: Specifications for hydraulic fluids in categories HFAE, HFAS, HFB, HFC, HFDR and HFDU

d The definition of compatibility for types of elastomers other than NBR 1 (e.g. FPM, EPDM, AU) may be agreed between the supplier and the end-users.

e The stage I determination is based upon a comparison of the mean flow rate of a fluid through a test membrane with its initial flow rate. Oils having good stage I filterability, but only a poor stage II

performance (see footnote l), are unlikely to give performance problems in use, unless extremely fine system filters are utilized.

f The stage II determination is based upon the ratio between the initial flow rate of fluid through the test membrane and the rate at the end of the test. It is considered that this part of the procedure is a more

severe test,and is more sensitive to the presence of gels and fine silts in the oil. Silts and gels can be present in an oil when it is produced, or can be formed as an oil ages, especially when hot. An oil with

good stage II filterability is unlikely to give filtration problems even in the most extreme conditions, and with fine (less than 5 μm) filtration present. Thus, it is suitable for use in more critical hydraulic and

lubrication systems.

Procedure A 30 30

a A typical application is for machines with combined hydraulic and plain bearing way lubrication system where it is necessary to minimize vibration or intermittent sliding (slip-stick) at low

speed.

b Square millimetres per second (mm2/s) is equivalent to centistokes (cSt).

c The definition of compatibility for types of elastomers other than NBR 1 (e.g. FPM, EPDM, AU) may be agreed between the supplier and the end users.
