Testing crude oil, biodiesel, and other petroleum products at atmospheric pressure risks thermal breakdown before true boiling points are reached. ASTM D1160 solves this by using reduced pressures to distill samples safely and accurately.
At Performance Distillation Solutions, we design equipment that meets these standards with precision. However, knowing the top features to look for in ASTM D1160-compliant equipment is key to getting reliable results.
From vacuum control to automation and safety, this blog breaks down what your D1160 system should deliver and why it matters.
Key Takeaways
- The right ASTM D1160 system gives you accurate data without risking thermal damage to sensitive oil samples.
- Built-in automation and smart controls save time and help your team stay consistent across every test.
- When your equipment is designed for performance, your lab can focus on results instead of troubleshooting.
Stable Vacuum Control Is Non-Negotiable
Vacuum stability is critical for accurate ASTM D1160 results. Testing petroleum products like diesel, gasoline, and crude oil at reduced pressures allows them to be completely vaporized without damage, but only if vacuum levels stay consistent.
A range of 0.1 to 10 mmHg is typical. Dual pressure sensors and PID regulation gives you more accurate vacuum control which will give you better data. In quality control or refining, unstable pressure leads to unreliable results, and that’s a risk no lab can afford.
Accurate Temperature Control for High-Boiling Samples
Handling crude oil, diesel, or kerosene calls for precise temperature control and a maximum temperature of 400 °C. This feature is essential in ASTM D1160 systems because it allows compounds to vaporize fully without degrading. Atmospheric distillation methods typically can’t handle these conditions without risking thermal damage.
High-resolution sensors help maintain thermal stability, keeping the process within safe limits. This level of control supports accurate boiling point data and consistent analysis.
For labs focused on product quality, compliance, or working with certified reference materials, temperature accuracy directly impacts results. In the petroleum industry, it plays a critical role in everyday lab operations and production decisions.
Automated Systems That Create Accurate, Repeatable Testing
Automation is a top feature in ASTM D1160 systems. With PC-based control, the equipment adjusts temperature, pressure, and distillation rates automatically. This reduces operator error and keeps test conditions consistent. It’s especially useful when testing naphtha, diesel, or crude oil samples in high-volume labs.
Automated methods help labs maintain accuracy, meet compliance goals, and improve throughput. They also support repeatable results across shifts and operators.
For quality control, boiling point testing, or meeting industry standards, automation makes the process more reliable without adding complexity.
Built-In Test Methods That Support Compliance and Consistency
Having ASTM D1160 test method protocols built into the system is essential for labs that need reliable, repeatable results. Pre-programmed methods help operators follow the correct steps for each run, without second-guessing settings or wasting time on manual setups.
Real-time tracking of ACT and AET adds clarity to the process, making it easier to evaluate samples, pass audits, and maintain accurate data across tests. This kind of documentation supports compliance and helps labs demonstrate alignment with industry standards.
For labs analyzing jet fuel, gasoline, or crude oil, these features simplify operations and improve overall analysis. When consistency and traceability are key to determining boiling points or evaluating fuels, having the right protocols in place makes all the difference.
Safety Features That Protect Samples, Systems, and Staff
In any lab working with crude oil, naphtha, or other high-temperature fuels, safety features aren’t optional—they’re essential. ASTM D1160 systems handle intense heat and pressure ranges, so built-in protections help prevent accidents and keep tests running smoothly.
Automatic shut-offs are a key safeguard. They stop the system if temperature or pressure moves beyond safe limits. This protects the equipment, the operator, and the sample itself.
Systems designed with enclosed components and easy-to-monitor layouts reduce risk while improving efficiency. In daily operations, these features help labs maintain productivity without sacrificing control.
Safety also supports better data. Preventing unexpected shutdowns or test failures means you lose fewer samples and avoid repeating tests. That adds up to more reliable analysis, lower operating costs, and fewer delays in refining workflows.
For any lab running D1160 methods, reliable safety mechanisms are just as important as performance. They keep the process consistent and the team protected.
Common Pitfalls to Avoid in D1160 Equipment Selection
Choosing the right ASTM D1160 system isn’t just about meeting the basics. It’s about selecting equipment that supports accurate analysis, dependable data, and efficient operations. Here are a few common pitfalls that can hold labs back.
Pitfall 1: Limited vacuum range
Some systems don’t cover the full vacuum range needed to handle the distillation of high-boiling crude oil and other fuels. If your system can’t manage 0.1 to 10 mmHg, you may not be able to fully evaluate boiling points across your full sample range. That could limit your ability to apply the test method to some crude testing.
Pitfall 2: Manual logging of data
Manual tracking of temperature, pressure, and volume slows down your process and increases the chance for error. It also makes reporting more difficult. Automated data capture helps maintain consistency, supports compliance, and protects the integrity of your test results.
Pitfall 3: Inconsistent Support and Spare Parts Access
Your equipment still needs routine maintenance. When replacement parts are hard to find or tech support is delayed, lab work gets disrupted. For labs that run critical tests tied to refining, scheduling, or product delivery, downtime is a costly problem. Keeping spare parts in your laboratory is key to keeping your equipment running at the highest level.
Before you choose, ask these questions
- Does the system cover your full temperature and vacuum range?
- Is it compatible with the methods you run most often?
- Are the distillation column components built for long-term daily use?
- Can it maintain precise temperature control across various samples?
- And most importantly, can you get support when it counts?
Taking time to ask the right questions now can help your team avoid performance issues and protect long-term solutions for accurate, repeatable distillation.

Frequently Asked Questions
What is the pressure for ASTM D1160?
ASTM D1160 typically uses a pressure range of 0.1 to 10 mmHg. This reduced pressure allows high-boiling oil samples to distill at lower temperatures, preventing thermal degradation. Precise vacuum control in this range is critical for accurate, repeatable results.
What is ASTM D1160?
ASTM D1160 is a vacuum distillation test method used to determine the boiling range of high-boiling petroleum products like crude oil and biodiesel. It allows samples to be partially or completely vaporized under low pressure, avoiding damage from high heat. It’s widely used in labs for analysis, refining, and quality testing.
What is the difference between ASTM D1160 and D86?
ASTM D86 is for lighter products like gasoline and jet fuel and runs at atmospheric pressure. ASTM D1160 is for heavier, heat-sensitive samples like crude oil and uses vacuum distillation. D1160 prevents thermal breakdown by reducing boiling temperatures, making it better suited for complex or high-boiling oil samples.
What is the maximum liquid temperature for ASTM D1160 testing?
The maximum liquid temperature for ASTM D1160 testing is typically 400°C. This allows high-boiling petroleum products to be distilled without decomposition. Staying below this limit, especially under reduced pressures, helps protect the sample and maintain data accuracy.
Why is ASTM D1160 important in the petroleum industry?
ASTM D1160 plays a key role in the petroleum industry by allowing accurate measurement of boiling points for heavier crude oil fractions. It supports product development, quality control, and regulatory compliance for fuels that cannot be tested at atmospheric pressure.
Can petroleum products be completely vaporized using ASTM D1160?
Yes, using ASTM D1160 under reduced pressures, many petroleum products can be completely vaporized without thermal breakdown. This is especially important for testing crude oil or other heavy fractions that would degrade under standard conditions.
