Lubricant Analysis Sampling

Taking a Representative Sample

Use only clean laboratory sample bottles. Do not use a non-laboratory sample bottle (e.g. soda bottle/water bottle). Take samples while the system is operating under normal conditions or immediately after shutdown while it is still at operating temperature. Make sure the sample point is cleaned and flushed prior to filling a sample bottle. If multiple sample points are available, make sure all samples are taken from the same point.

Condemning Limits

Every oil is different, and every oil manufacturer uses different additive chemistry. This means each oil has a unique set of condemning limits. For a meaningful and accurate analysis evaluation, the correct condemning limits should be applied to each oil. Therefore, it is important to establish the correct condemning limits with AMSOIL Industrial Lubricant Analysis so the analyst can provide proper recommendations.

Suggested Sampling Methods

Although the equipment manufacturer's recommendations provide a good starting point for preventive maintenance practices, sampling intervals can vary. The equipment's importance to production is a major consideration for determining sampling frequency. So, too, are environmental factors such as hot, dirty operating conditions, short trips with heavy loads and excessive idle times.
