Standard Test Method for Gauge Vapor Pressure of Liquefied Petroleum (LP) Gases (LP-Gas Method).
Get more information about the standard at ASTM D1267-18
ASTM D1267 is a standard test method for determining the gauge vapor pressure of liquefied petroleum (LP) gases. This method is essential for assessing the volatilit’+y9993+ and handling characteristics of LP gases, ensuring their safe storage, transportation, and utilization. By providing a reliable method for measuring the vapor pressure of liquefied petroleum gases, ASTM D1267 plays a crucial role in maintaining safety standards and ensuring the efficient use of these gases across multiple sectors.
Details
The test method covers the determination of gauge vapor pressures of liquefied petroleum gas products at temperatures ranging from 37.8 °C (100 °F) up to and including 70 °C (158 °F). The procedure involves placing a sample of the LP gas into a test apparatus designed to measure vapor pressure accurately. The sample is brought to the desired test temperature, and the equilibrium pressure is measured using a pressure gauge. This measured pressure reflects the volatility of the LP gas, which is crucial for determining appropriate storage and handling requirements. The vapor pressure of LP gases is vital for several reasons:
- Safety: Ensuring that storage vessels and transportation containers can withstand the internal pressures exerted by the gas at various temperatures and prevents accidents and equipment failure.
- Quality Control: Vapor pressure is an indicator of the composition and purity of the LP gas, affecting its performance in end-use applications.
- Regulatory Compliance: Adhering to industry standards and governmental regulations regarding vapor pressure is mandatory for legal and safe operations.
This test method is not applicable for products containing significant amounts of non-condensable gases or for mixtures where the vapor pressure is influenced by such components.
Industries & Applications
ASTM D1267 is widely used across various industries:
- Energy sector: Producers and distributors of liquefied petroleum gases use this standard to ensure their products meet safety and quality specifications
- Manufacturing: Industries that utilize LP gases as fuel or feedstock apply this test method to verify the suitability of the gas for their processes
- Transportation: Companies involved in the shipping of LP gases rely on vapor pressure data to select appropriate containers and comply with transportation regulations
- Consumer products: Manufacturers of appliances and equipment that use LP gases, such as propane grills and heaters, depend on this standard to ensure product safety and performance
