The precision statement for this method was determined on steam turbine oils. The test is considered to start at this point. Once the required bath temperature is found, d934 at that asm Open tube ends to be ground and? Several hours soaking in this manner often serves to loosen all adhering deposits except iron oxide.

All dimensions are in millimetres inches 1. Use Test Method D when the acid number exceeds 0.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed asm If these steels are not available, other equivalent steels may be used, provided they are found to be satisfactory in comparative tests using Test Method D To allow for heating of the stem portion of the thermometer above the immersion point in the upper portion of the test cell, subtract 0.

Soft copper wire of an equivalent grade may also be used. The values given in parentheses are for information only. Add a desiccant bag that has been folded lengthwise to?

An exception is where the oil is known to have a life shorter than h, the sampling is at the discretion of the operator. Slide the catalyst coil over the inlet of the oxygen delivery tube.
