The chain operates over 9, stores and its headquarters is located in Goodlettsville, Tennessee, a suburb of Nashville.
Such standards would be of great benefit to end users in reducing the time and expense associated with evaluating potential products. Product management is becoming more important for worker health and process productivity, and standards or guidance in this area are important.
This article discusses progress on development of fluid and lubricant standards. To protect worker health, GM developed standards more than decade ago to ensure the use of only highly refined base oils, and has largely implemented them.
Performance standards pose a somewhat greater challenge. GM now has well defined standards for hydraulic fluids, gear oils, etc. Quality control parameter checks have been systematized and implemented within GM. Plants now have references with which to check products delivered.
The current state of GM standards will be reviewed. A systematized effort to improve and standardize lubricant and fluid management is also critical, and will be covered briefly.
When I became involved in industrial lubricants, there were some standards available, although many were company standards and not true consensus standards.
In General Motors, there was a Fisher Body Materials specification that was over ten years old, seldom used and probably inadequate. For maintenance lubricants hydraulic fluids, gear lubricants, way oils, spindle oils, greases and so onthere were a lot of good test methods available, American Society for Testing and Materials ASTM International Standards Organization ISO and others.
Also, since on the industrial side GM is actually the direct customer, we could write our own standards. The situation was more difficult for metal removal fluids MRFs.
To complicate matters, there were only a handful of consensus test methods available, and many parameters were more or less completely undefined.
On a corporate basis, we had far too many different MRFs and tended to purchase MRFs as specialized products rather than commodities. Our expectations were based on company reputation, price or gut feel — not hard data.
We did not have systematic checks of key quality control parameters e. When tool life suddenly dropped in a given system, there was no easy way to begin to eliminate a change in MRF formulation as a possible cause.

GM plants sometimes experienced periodic health and safety issues, such as dermatitis and respiratory complaints. This group, at the time of this article more than in number, is composed of anyone involved in plant lubrication or fluid management issues.
LS2 is composed of plant and central staff people, oilers, maintenance managers, capacity assurance coordinators, machine operators, environmental engineers, etc.
Some are salaried; most are hourly. All share a desire to do a better job on lubricant and fluid issues within GM.
While no one LS2 member has all of the knowledge, collectively they are a tremendous resource and the reason why GM has made considerable progress on lubrication issues.
It is worth noting that our chemical managers and suppliers also participate in LS2 meetings and add considerable value. We must continuously seek plant experience and attempt to correlate this with the specifications, semi-quantitatively or at least qualitatively.
We then continuously iterate all steps, from rechecking the parameters are there new demands or constraints? Worker Health The first priority in setting specifications is protecting the health of our workers. Rather than specifying refinery processing conditions as the International Agency for Research on Cancer IARC had, it was more important and more reasonable to specify the quality of the finished base oils used in industrial lubricants.
GM developed and released a base oil specification in SinceGM has required that any mineral oil components of lubricants and fluids must meet these base oil specifications for metals, polynuclear aromatic compounds, PCBs, halogens and Mutagenicity. We have and continue to verify that virtually all maintenance lubricants and MRFs in GM plants meet them.
Performance Specifications Next was the task of developing performance specifications. LS2 clearly recognized that maintenance lubricants and MRFs must be approached differently. MRFs, however, are just too complex to write complete, hard specifications in any reasonable time period.
The philosophy for metal removal fluids had to be different than that for maintenance lubricants; we must accept less than perfection. The intent of the specification is to improve our odds of finding an acceptable fluid.comprehensive case analysis of general motors Recently there have been doubts concerning the survival of General Motors.
These doubts stem in part from the firm’s unawareness of the automotive industry’s external business environment. Summary of the Case. The class action against General Motors of Canada Limited (“GM”) and General Dynamics Land Systems – Canada Corporation (“GD”) was commenced by Statement of Claim issued February 4, System Outage: The Department of Defense (DoD), Defense Manpower Data Center (DMDC) technical issues have been resolved related to DS Login and webkandii.com Veteran business owners can now access the site again via DS Login and non-Veteran business owners and reps via webkandii.com again.
