3. TECHNICAL REQUIREMENTS:
3.1 Materials:
This semi-fluid lubricant shall consist of a diester base fluid thickened with a lithium stearate soap and other suitable additives (corrosion protection. EP additives). (See 8.1).
4.2.2 Qualification Tests: All technical requirements are qualification tests and shall be performed prior to or on the initial shipment of lubricant to a purchaser, when a change in ingredients and/or processing requires reappoval as in 4,4.1 .1, and when purctiaser deems confirmatory testing to be required.
4.2.2.1 Qualification: For qualification, all tests described in Table 1 shall be performed by an approved laboratory authorized by the purchaser, for release of a new semi-fluid lubricant to this specification. The laboratory will provide a recommendation for release to the purchaser who then has authority and may make a final release. In cases of deviation in composition or manufacturing process, written notification is required and such deviations are permissible only after receiving release by the purchaser.
4.3 Sampling and Testing:
4.3.1 For Acceptance Tests: Sufficient lubricant shall be taken at random from each batch to perform all required tests. The number of determinations for each requirement shall be as specified in the applicable test p4-ocedure.
4.3.1.1 A batch is defined as a quantity of formulated material mixed as one production entity.
4.4 Appoval:
4.4.1 Lubricant shall be approved by purchaser before lubricant for production use is supplied, unless such approval be waived by purchaser. Results of tests on the production lubricant shall be essentially the equivalent to those on the approved (qualified) sample.
