ASTM D5800 Lubricating Oil Evaporation Loss Tester

I. Purpose and scope

This instrument is designed and manufactured as per procedure A of SH/T 0059 and procedure A of ASTM D5800 Standard Method for Evaporation Loss of Lubricating Oils by the Noack Method.

It is used to determine the evaporation loss of lubricating oils (particularly engine oils). The evaporation measured is reported as percent total loss.

II. Working conditions

1. The instrument should be placed on a fixed and flat workbench. Cross-ventilation should be avoided as far as possible in the environment.

2. No naked fire is allowed around the instrument during operation because of inflammable materials.

3. The instrument should be placed in the dry and ventilated environment.

4. The power supply should be single-phase and three-wire. The instrument must be grounded well.
