ASTM D187-24

Overview

ASTM D187-24: Standard Test Method for Burning Quality of Kerosene sets out a qualitative procedure for determining the burning properties of kerosene intended for illuminating purposes. Developed by ASTM International, this test method is widely recognized for its role in ensuring kerosene’s reliability, performance, and safety when used in lamps and similar devices. The method evaluates critical factors such as flame characteristics and chimney deposits under controlled conditions, providing valuable insights for manufacturers, distributors, and regulatory bodies involved with petroleum products.

Key Topics

Burning Quality Evaluation:

• The test examines how kerosene burns over a 16-hour period in a specifically designed lamp.
• Key performance indicators include:
  • Changes in flame shape, height, and width during the test
  • Average burning rate
  • Density and color of chimney deposits formed

Qualitative Focus:

• This method is qualitative rather than quantitative, emphasizing visual and descriptive assessment rather than precise numerical measurements.
• Limits and acceptability criteria for flame and deposits must be specified in any kerosene specification referencing ASTM D187.

Sampling and Safety:

• Proper sampling is crucial to obtaining representative results, following ASTM D4057 and D4177 procedures to avoid contamination.
• Strict adherence to safety, health, and environmental practices is emphasized, given the combustible nature of kerosene and test reagents.

Test Apparatus and Procedure:

• A specified lamp assembly, wick type, and sight gauge are used for consistent results.
• Detailed preparation and pre-conditioning of equipment, including cleaning chimneys and pre-treating wicks, are required before testing.
• The procedure involves lamp set-up, wick trimming, test initiation, observation, and documentation of results.

Applications

Practical Value for Industry:

• Kerosene Suppliers: Ensures product meets acceptable burning performance for consumers, reducing complaints and safety incidents.
• Lamp Manufacturers: Verifies compatibility of lamps and wicks with common kerosene products.
• Regulatory Compliance: Assists authorities and standards organizations in certifying kerosene brands for safe public use.
• Quality Control: Used by laboratories in batch testing to monitor consistency across production lots.

End-User Benefits:

• Helps guarantee a smokeless, stable flame and minimal chimney sooting-key for safety, air quality, and lighting efficiency.
• Reduces maintenance and cleaning frequency for users of kerosene lamps.

International Relevance:

• Developed according to WTO TBT principles, making it suitable for global trade and regulatory harmonization.

Related Standards

Key referenced and associated standards include:

• ASTM D3699: Specification for Kerosine - defines physical and compositional requirements for kerosene products.
• ASTM D4057 & D4177: Practices for manual and automatic sampling of petroleum and petroleum products.
• ASTM D91: Test Method for Precipitation Number of Lubricating Oils - occasionally used for materials in kerosene testing.
• ASTM D4175: Terminology relating to petroleum products, liquid fuels, and lubricants.
• IP 10 (Energy Institute): A quantitative test for wick-char-forming tendencies in kerosene; provides complementary but distinct information to ASTM D187.

For those involved in fuel quality assurance or regulatory compliance, referencing and understanding ASTM D187-24 alongside these associated standards ensures comprehensive kerosene burning quality evaluation and safer market products.
