What is the maximum allowable amount of suspended solids in heating oil?

0.01% by volume
0.5% by volume
1% by weight
0.1% by volume

The correct answer is: 0.01% by volume

The maximum allowable amount of suspended solids in heating oil is 0.01% by volume. This stringent limit is established to ensure the proper functioning of oil heating systems and equipment. Suspended solids can include dirt, rust, and other particulates that, if present in higher concentrations, could lead to clogging of filters, impairment of burner operation, and overall reduction in system efficiency. Maintaining low levels of suspended solids is crucial for protecting the integrity of fuel delivery systems, ensuring clean combustion, and minimizing maintenance issues. Hence, the correct answer reflects a critical standard for fuel quality in the heating oil industry.
