Foreword

Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Tourism, Trade and Industry established under Cap 327, of the Laws of Uganda. 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/SPS Agreements 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 representatives of consumers, traders, academicians, manufacturers, government and other stakeholders.

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.

This standard is a revision of US 249:2000/EAS 159 and replaces that document in whole.

Introduction

Due to the technological advances that have occurred since the publishment of US 249:2000/ EAS 159, it has become necessary to keep abreast with such changes, hence the revision of this standard.

It has become necessary to sub-divide this standard into four parts.

US 249-1:2013 informs about the current engine oil categories per classification.

US 249-2:2013 specifies requirements for engine oil as used in gasoline engines and

US 249-3: 2013 specifies requirements for engine oil as used in diesel engines.

US 249- 4: 2013 specifies requirements for engine oil as used gasoline engines for four –stroke- cycle motorcycles and associated drive trains

In addition to the above US series, US ISO 13738 specifies requirements for two- stroke cycle gasoline engine oils (Categories EGB, EGC & EGC)engines.

Engine Oils- Performance Classification- Part 2: Specification for Spark Ignition (petrol) engines

1 Scope

This Draft Uganda Standard specifies quality and performance requirements for engine oil for spark ignition (petrol)engines of passenger cars, light duty trucks and vans, meeting or exceeding API service category SJ, ILSAC category GF-5 or equivalent ACEA performance categories. .

It does not cover engine oil for compression ignition (diesel) engines, aviation equipment, generators, outboard motors, lawn mowers, railroad locomotives or ocean going vessels.

Note: Engine oil specifications for diesel engines and motorcycles are specified in other standards.

less than 0.08 % mass phosphorus in the form of ZDDP shall also pass the wear limits in Test Method D5302 (see also footnote J ). E An oil-related stuck ring occurs on a piston with an individual oil ring land deposit rating <2.6.

M Determine cam wear according to Test Method D6891. Seven wear measurements are made on each cam lobe and the seven

measured values are added to obtain an individual cam lobe wear result. The overall cam wear value is the average of the twelve

individual cam lobe wear results N

Report

A The limits shown are based on those applied in U.S. market requirements. ACEA will continuously review the situation to ensure that

these limits are appropriate for European vehicles and lubricants. B Until a new CEC Test Method is developed, the gasoline sludge protection performance of engine oil formulations must be proved by

the M 271 sludge test procedure as described by Daimler AG. Test results obtained by the M 271 procedure will be accepted under the

condition that they come from test rigs being referenced and quality controlled by Daimler AG. Limits are based on the same reference oil

as with the old M111 sludge test. C ACEA considers the CEC L-54-T-96 test the only valid comparator against which claims of lubricant fuel economy improvement should

be made. D May be performed as soon as it becomes available as an alternative to the DV4 test. ACEA will decide when the DV4 test will be finally

deleted from this specification. CEC-L-093-04 (DV4 Test) test results obtained in accordance with the ATIEL guidelines may be used by a

grandfathering process also after this test has become unavailable to run and is replaced by the CEC-L-106 (DV6 Test) procedure. E. Not all parameters are yet official CEC parameters. C2 limit for inlet cam wear under definition.

F. Test report has to give measured values before & after the test, all measurements to be taken in the same lab. Note: TAN is considered

to become performance criteria in the future. Not all parameters are yet official CEC parameters. G

. Limit as applied to C1.

4.4.3 ILSAC GF- 5

All engine oils making claims of meeting ILSAC GF-5 shall conform to engine test requirements as stipulated in table A.1 (see Annex A). These shall be indicated in a certificate of conformance from an accredited testing laboratory and shall meet requirements as stipulated in section 4.1.5.3.

5 Packaging and Labelling

5.1 Packaging

The condition of the drums or smaller containers and the bulk tankers into which the engine oil is filled shall have no detrimental effect on the quality of the engine oil during normal transportation and storage. Only containers of the same size filled with oil of the same batch identification shall be packed together in a carton. Prior to use, containers shall be firmly secured with an aluminium tamper-proof seal.

5.2 Labelling

5.2.1 The following information shall appear in legible and indelible marking on each container and each carton (if used):

a) product name for single performance engine oil „ Petrol Engine Oil‟

b) or the product name for multiple performance level engine oil „ diesel/ petrol engine oil‟

c) the manufacturer's identification and/or distributor‟s name;

d) API and ACEA service classification or ILSAC classification if appropriate.

xx © UNBS 2013 – All rights reserved

e) SAE viscosity grade;

f) Relevant quality and certification marks ; see section 6.2.3

g) batch identification;

h) quantity.

i) origin of the product/Made in.

j) Expiry date in the form "dd/mm/yyyy"

5.2.3 Quality and Certification Marks

5.2.3.1 API Service Symbol ‘donut’

5.2.3.1.1 Single Performance Level

The mark shall be divided into three sections as shown in figure 1.

The oil‟s performance level in the top half

The centre indicating oil‟s viscosity (SAE oil Viscosity)

bottom level to indicate energy conserving or resource conserving properties if present.

Figure 1- API symbol for engine oil of single performance level

5.2.3.1.2 Multiple Performance levels

Oils designed for compression ignition (diesel) engines might also meet requirements for spark ignition (gasoline) engines .. For these oils the designation is “C” category first followed by the “S” category. “C” category oils have been formulated primarily for diesel engines and may not provide all of the performance requirements consistent with vehicle manufacturers‟ recommendations for gasoline-fueled engines.

Note: Engine Oils for compression ignition (diesel) engines shall meet requirements as stipulated in US 249-3.

Note: appropriate figure for multi performance level engine oil is as shown in clause 5.2.3.1.3 of US 249-3.

5.2.3.2 API Certification Mark, ‘Starburst’

An oil displaying this mark shall meet the current engine protection standard and fuel economy requirements of the International Lubricant Standardization and Approval Committee (ILSAC)
