What petroleum products require 3 h ± 5 min in the bath?

Select all that apply

• Aviation Gasoline and Aviation Turbine Fuel

• Natural Gasoline

• Automotive Gasoline

• Diesel Fuel

The reason for this use of larger silicon carbide grains in the final preparation is to produce asperities (controlled roughness) on the surface of the copper.

• True

• False

• ± 1.0⁰C (2.0⁰F)

• ± 2.0⁰C (4.0⁰F)

Copper strip may be used repeatedly but shall be discarded when:

select all that apply.

• the strip's surface shows pitting or deep scratches that cannot be removed by the specified polishing procedure

• the strip becomes tarnished

• the surface becomes deformed

• the dimensions for the copper strip fall outside the specified limits
