Liquified Petroleum (LP) Gases Testing According to ASTM D1835-20
ASTM D1835-20, Standard Specification for Liquified Petroleum (LP) Gases, defines and provides specifications for the four most common products commonly referred to as liquified petroleum gases including Propane, Butane, and Propane/Butane Mixtures. To compare your needs to our capabilities, please select the appropriate item from the table below to view our listing of capability.
| Product | Description |
| Commercial Propane | n-a hydrocarbon product for use where high volatility is required. Commercial propane is suitable for certain low severity internal combustion engine applications. |
| Commercial Butane | n-a hydrocarbon product for use where low volatility is required. |
| Commercial PB Mixtures | n-mixtures of propane and butane for use where intermediate volatility is required. |
| Special-Duty Propane | n-a hydrocarbon product for use where high volatility is required tailored to meet the restrictive needs of internal combustion engines operating under moderate to high engine severity. Special-Duty Propane is equivalent to HD-5 Propane as defined in GPA Midstream Standard 2140. |
