🔍 Key Concepts

• Definitions of Grade A, B, and C petroleum products in 46 CFR (look at how they combine Reid vapor pressure and flash point limits • How Reid vapor pressure (psia) divides the grades (note the key cutoff around 8.5 psia and 14 psia) • The requirement that Grade C products still have a relatively low flash point (below a certain temperature) but a lower vapor pressure than Grades A and B

💭 Think About

• First, sort out which Reid vapor pressure ranges go with Grade A, Grade B, and Grade C. Which grade is associated with the lowest vapor pressure range? • Then, look at the flash point requirement for Grade C. Does it need to be below or above 80°F? Which options meet that flash point condition? • Match the choice whose combination of vapor pressure AND flash point lines up with the Grade C definition—then eliminate choices that clearly fit Grade A or Grade B instead.

✅ Before You Answer

• Verify from the regulations that Grade C requires a flash point below 80°F and a Reid vapor pressure less than 8.5 psia (or current equivalent wording—verify exact numbers). • Check which choice(s) show a Reid vapor pressure below 8.5 psia AND a flash point below 80°F; eliminate any that fall into the 8.5–14 psia or 14 psia and above ranges. • Confirm that any option that explicitly states a vapor pressure above 8.5 psia but less than 14 psia corresponds to Grade B, not Grade C, so it can be ruled out for this question.
