1112.1 Procedure
Samples of lubricating products are to be obtained by district Operations personnel when requested by the Director, General Services or the district General Services Manager.
If samples are taken, the sample size shall be as follows:
1112.1.1 Universal Hydraulic/Transmission Oil, Multi-Grade Lubricating Oil, Grade 15W-40, Multi-Purpose Gear Oil- Grade SAE 80W-90, Dexron II Transmission Fluid
Samples are to consist of one quart (1 liter) from each designated lot or blend. The samples are to be submitted to the Laboratory in one-quart (1 liter) screw top cans.
1112.1.2 Multi-Purpose Lithium Grease NLGI Grade 2
Samples are to consist of one gallon (4 liters) from each designated lot or blend. The samples are to be submitted to the Laboratory in one-gallon (4 liters) friction top cans.
Submit these samples to the Laboratory as directed in EPG 106.5.2 Submission of Laboratory Samples.
1112.2 Laboratory Testing Guidelines
This article establishes procedures for Laboratory testing and reporting samples of lubricating products. The requirements are set forth in a bid request.
