In the Bottom Sediment & Water Test, what is the maximum acceptable sediment percentage?

• A. Max 0.01% sediment
• B. Max 0.5% sediment
• C. Max 0.1% sediment
• D. Max 1.0% sediment

Answer: (C)

The test focuses on cleanliness by measuring how much sediment remains in a sample, expressed as a percentage of the total sample weight. You separate the sediment and water, weigh the sediment, and compare it to the whole sample to get the percentage. The accepted limit is 0.1% because only a very small amount of sediment is allowed to ensure the sample is clean enough to protect equipment and performance. If sediment is higher than 0.1%, the sample wouldn’t meet the required cleanliness standards. The other numbers would either let in too much sediment (0.5% or 1.0%) or be impractically strict (0.01%) for routine testing, which is why 0.1% is the correct threshold.
