Professional Accelerated Life Testing Services
What Is Accelerated Life Testing?
Accelerated Life Testing (ALT) is a testing methodology that exposes a product to stresses beyond normal use conditions — extreme temperature, humidity, vibration, mechanical loading, or electrical stress — to compress years of expected field use into a matter of weeks or days.
Under normal conditions, gathering meaningful failure data can take years. By increasing the frequency and intensity of stress loads while removing insignificant variables, ALT reveals how and when a product is likely to fail. This process turns a multi-year unknown into an actionable engineering report in a fraction of the time.
Get StartedWhy Accelerated Life Testing Matters for Your Product
A product that fails in the field costs far more than one that fails in the lab. ALT compresses years of real-world wear into weeks, so you find design and manufacturing weaknesses before your customers do — not after a recall.
-
Predict lifespan: Predict product lifespan before it ever reaches a customer.
-
Identify weaknesses early: Identify design and manufacturing weaknesses early, when fixes are cheap. This is better than waiting until after tooling is locked or units are in the field.
-
Reduce claims and returns: Reduce warranty claims and returns by catching failure modes before launch.
-
Avoid costly recalls: Avoid costly recalls that damage both budget and brand reputation.
Types of Accelerated Life Testing We Perform
Not every product needs the same kind of test. We tailor the ALT approach to what you actually need to learn.
Qualitative ALT (HALT & MEOST)
These tests focus on applying combinations of rapid changes to temperature, vibration, etc., until a design fails or an extreme limit is reached. This rapidly identifies weaknesses in design and manufacturing.
Quantitative ALT (QALT)
QALT is built to estimate an actual service life or MTBF (Mean Time Between Failures). We develop a custom test plan defining which stresses to apply and at what levels, based on your product's real application.
Accelerated Aging
For products where shelf life or storage life matters, we perform testing at elevated temperature and controlled humidity. By aging a product faster, we can estimate real-world shelf life in a fraction of the time.
Stresses & Standards Our ALT Programs Cover
Our test programs are built around the stress conditions your product will actually face in the field, and can be aligned to recognized industry standards.
Stress: Thermal stress
This includes high/low temperature exposure, thermal cycling, and thermal shock.
Stress: Humidity & moisture
This involves combined temperature-humidity testing to evaluate product resilience.
Stress: Vibration & shock
We test using random vibration, mechanical shock, and repetitive shock techniques.
Stress: Mechanical loading & fatigue
This requires cyclic loading to effectively simulate mechanical wear over time.
Stress: Electrical/voltage stress
This involves over-voltage and load-cycling conditions specifically tailored for electronics.
Compliance: Industry Standards
We test against or in accordance with MIL-STD-810, MIL-STD-883, ASTM F1980, IEC 60068-2, JESD22, RTCA/DO-160, and SAE J1455.
Our Accelerated Life Testing Process
Initial Consultation: We learn about your product, its use environment, and what you need to prove or discover.
Test Plan Development: Our engineers design a custom test plan specifying which stresses, at what levels, and for how long.
Custom Test Setup: We build or configure the fixtures and instrumentation needed for your specific product.
Test Execution: We run the test program, monitoring for failures and collecting time-to-failure data.
Failure & Data Analysis: We analyse failure modes and calculate reliability metrics like service life and MTBF.
Actionable Reporting: You receive a clear report with design recommendations, not just raw data.

How Long Does Accelerated Life Testing Take?
The lengths of timelines vary by product, the stresses applied, and whether you require results in a qualitative (HALT) or a quantitative (QALT) format. Qualitative testing may take only a few days, while quantitative service-life testing, with the additional consideration for statistical assurance, may take several weeks.
Frequently Asked Questions
1. How does Accelerated Life Testing work?
ALT works by exposing products to extreme conditions like high temperature, humidity, vibration, or mechanical stress to quickly simulate long-term usage and identify potential failure modes in a fraction of the time normal use would take.
2. What is the main goal of Accelerated Life Testing?
The main goal is to predict product lifespan, detect design and manufacturing weaknesses early, and give engineering teams the data needed to improve reliability before the product reaches the market.
3. What's the difference between ALT and HALT?
ALT is the broader category of accelerated testing methods. HALT is a specific qualitative form of ALT used to find design weaknesses, but it doesn't estimate a specific service life the way quantitative ALT (QALT) does.
4. What types of tests are included in Accelerated Life Testing?
Common test types include thermal cycling, vibration testing, humidity testing, mechanical load/fatigue testing, and accelerated aging (shelf-life) testing. These are selected based on your product's real-world use conditions.
5. Who should use Accelerated Life Testing services?
Manufacturers, product designers, and engineering teams in electronics, automotive, aerospace, medical devices, and consumer goods all benefit from ALT, especially before finalizing a design or launching a new product.
6. Can Accelerated Life Testing reduce product failure rates?
Yes. By identifying weaknesses early, ALT helps improve product design, reduce warranty claims, and lower the risk of field failures and recalls.
7. Do you test to industry standards like MIL-STD-810 or ASTM F1980?
Yes, our test programs can be designed to align with recognized industry standards including MIL-STD-810, MIL-STD-883, ASTM F1980, IEC 60068-2, JESD22, and others depending on your industry and product requirements.
8. What results do I get from an Accelerated Life Testing program?
You'll receive a full report including time-to-failure data, identified failure modes, reliability metrics like estimated service life or MTBF, and actionable design recommendations, rather than just raw test data.
9. Is Accelerated Life Testing the same as a warranty test?
Not exactly. ALT is a predictive engineering test designed to find and quantify failure modes before launch, which in turn helps you set realistic, defensible warranty terms and reduce future warranty claims.
