Accelerated Life Cycle Testing – Understanding the Different Types

   
When bringing a new product to market, manufacturers need to be confident that their product will perform as expected and withstand the rigors of real-world use. That’s where accelerated life cycle testing (ALT) comes in. ALT is a special type of testing that subjects products to extreme conditions to simulate long-term wear and tear. By doing this, manufacturers can see how their products will hold up over time and make any necessary changes before making them available to consumers or other manufacturers to be put into use. ALT can also help prevent product failures or costly recalls down the road.

There are three main types of accelerated life cycle testing: qualitative, quantitative, and accelerated aging.

Qualitative Testing

Qualitative accelerated life cycle testing such as HALT focuses on determining if a product will function as intended over its expected lifespan. The goal is to quickly determine if a product has any design or manufacturing weaknesses. Testing begins by subjecting the product to normal levels of stress that simulate real-world conditions, such as temperature and humidity, and increasing those levels until the product fails, exposing its weaknesses. Qualitative testing provides engineers with the information they need to improve the product design and increase its reliability. Qualitative accelerated life cycle testing is typically performed on aerospace, commercial, medical, and military products.

Quantitative Testing

Quantitative accelerated life cycle test (QALT) differs from qualitative testing in that it is used to determine the service life or mean time between failure (MTBF). Quantitative testing often requires developing a custom test plan based on the product’s intended use and the real-world stresses it will routinely be exposed to in the field. QALT test results are analyzed to calculate the estimated life span or MTBF of the product. It also includes measurements of the product’s performance over time. This type of testing is typically used for products with longer lifespans, such as medical devices. QALT is often performed using accelerated aging techniques, such as gamma irradiation or thermal cycling.

Accelerated Aging

Accelerated aging, or shelf-life testing, is used to determine how long a product can be stored before it begins to degrade. This type of testing is typically used for medical devices or other products to determine an acceptable shelf life. To conduct accelerated aging or shelf-life testing, test engineers will need to define the stress factors, which are the environmental conditions that can cause the product to age prematurely. Accelerated aging is usually performed using one or more of the following stressors: temperature, humidity, oxygen, light, or pressure.

Professional Accelerated Life Cycle Testing

When choosing a life cycle testing method, it is important to consider the needs of the project. If cost and time are major concerns, then qualitative accelerated life testing may be the best option. If accuracy is a major concern, then quantitative accelerated life testing or accelerated aging may be the best option. Each of these life cycle testing methods has its own unique benefits. The best life cycle testing method for your product will depend on its intended use and expected lifespan.

Benefits of Using a Product Testing Company in California

 

 
From aerospace components and medical devices to products used in our homes every day – they all undergo some form of product testing. Many consumers don’t realize the amount of testing that takes place before products are put into use or made available for purchase. However, product testing is a vital part of the development process. Using a product testing company before products go to market benefits both the manufacturer and the consumer.

Quality Assurance

One of the main purposes of using a product testing company is to ensure that your product meets specific standards before they are distributed and put into use. This is especially true in the medical industry, where product testing is essential to guarantee the safety of medical devices. Product testing can help you verify that your products meet USP and ISO 10993 standards before they leave your manufacturing facility. Consequently, using a product testing company is a vital step in the manufacturing process to ensure the quality of your products.

Product Endurance

As a manufacturer, you want to be sure that your products can withstand the rigors of use. A product testing company can help determine if your product can endure extended use and continue to perform as intended. This type of testing is beneficial to both the manufacturer and the consumer.

Defect Detection

Product testing can help to identify potential defects in a product before it hits the market. This is beneficial for both the manufacturer and the consumer. Identifying defects early on allows the manufacturer to make changes to the product before it has the opportunity to cause any harm or inconvenience to consumers. This can save the manufacturer money in the long run and protect its reputation.

System Integration

When manufacturing product components rather than the whole product, it is vital to test system integration. The component is tested within the system into which it is integrated.  All the components of a product must work smoothly and in unison. Otherwise, it can result in reduced performance, decreased life span, or complete failure. A product testing company can determine if the tested component is functioning as intended and does not impede the movement of any other components of the product and that all are working together as they should. 

Decrease Development Process

Product testing at various stages of the process can reduce development time by identifying issues early on. Waiting to test a product until right before sending it to market may reveal operational issues that could have been addressed sooner and result in additional development time and expense.

Reduces Liability

Product testing will determine the reliability and safety of the product. Ensuring these factors before the product goes to market or is put into use is crucial. Product failure or malfunction can result in the product becoming a safety hazard, thus increasing the potential for liability or class action lawsuits against the manufacturer. Even if the problem is identified and a recall is implemented before it results in injury or property damage, the recall process can be costly and negatively impact the manufacturer’s reputation. Enlisting the services of a product testing company can help ensure that your product does not present a safety hazard and that your reputation remains intact.

HALT and HASS Testing – Understanding the Difference

 

 

When you buy a product, you want it to do what it is supposed to do, be dependable, and have a long lifespan. These are the qualities that create customer satisfaction and ensure product safety. To be sure that products will perform as expected, they are tested during development. Many are tested under extreme environmental conditions. This includes automobiles, aerospace components, and more. There are two types of testing commonly used – HALT and HASS testing. Let’s look at what each type of testing involves and how they differ.

What is HALT Testing?

 

HALT is an acronym for Highly Accelerated Life Testing. As the name implies, HALT testing subjects products to extreme conditions far beyond what they are intended to withstand in real-world use. The purpose of HALT is to find the product’s limits or weaknesses so that they can be redesigned and improved before the product goes to market.

 

To perform HALT testing, engineers first identify methods to monitor the product during testing to help identify what might be causing a failure mode. They then apply the HALT process that will push the product past its limits in each of those potential failure modes. HALT is conducted using specialized HALT chambers. These chambers can rapidly change temperature and apply vibration and other stresses to the test product.

What is HASS Testing?

 

HASS is an acronym for Highly Accelerated Stress Screening. HASS testing is similar to HALT testing in that it subjects products to extreme conditions. However, the purpose of HASS is not to find the product’s limits. Rather, it is conducted on production units to identify any units that might be defective and likely to fail during normal use..

 

To perform HASS testing, engineers develop a test profile based on actual test results. The stresses are tailored based on the limits discovered during the HALT. Once a profile has been created, a proof of screen is performed to make sure the test levels are not over testing good hardware. HASS is typically conducted using environmental chambers which subject the test product to rapid changes in temperature and humidity as well as exposing it to vibration testing.

HALT testing

What Industries Use HALT?

 

HALT testing is commonly used in the automotive, aerospace, and electronics industries. It is also used to test other products that must operate reliably under extreme conditions, such as medical devices and high reliability products.

 

What Industries Use HASS?

 

HASS testing is commonly conducted on production units of electronic hardware which includes items such as printed circuit boards (PCBs) and other assemblies. It is also used to test other products such as mechanical parts and assemblies.

 

Benefits of HALT

 

HALT testing has several benefits. First, HALT can identify the product’s limits. This information can be used to improve the product design. Second, it can identify potential failure modes. This information can be used to redesign the product or develop new test methods to screen for those failure modes. Finally, HALT can save time and money by identifying problems early in the development process.

 

Benefits of HASS 

 

HASS testing also has several benefits. First, HASS can identify defective units before they are shipped to customers. This can save money and reduce customer dissatisfaction. Second, it can improve product quality by helping to identify manufacturing defects. Finally, HASS can save time by identifying problems early in the production process.

Environmental Stress Screening – The Benefits of EES Testing

 

 

Environmental stress screening, or ESS, is a process used to identify potential problems in products or systems before they are put into service. By subjecting products or systems to conditions that simulate the real-world environment, ESS can uncover weaknesses that would not be apparent during normal operation. The levels of stress applied during ESS testing often exceed the stress those products would normally experience to precipitate failures and reduce test time.

ESS Benefits

 

ESS is often used on products expected to operate for long periods without failures, especially electronics such as medical devices, aerospace components, or military equipment. By testing products under extreme conditions, manufacturers can be confident that their products will perform as intended when they are used. By identifying potential problems early on, ESS can save manufacturers time and money by preventing costly recalls or repairs down the line. For some products, environmental stress testing is a legal or industry requirement. Let’s take a look at some of the most common types of ESS.

 

Thermal Cycling Testing

 

Thermal cycling is one of the most common types of environmental stress screening and is often used on electronic components. It involves subjecting a product to extreme hot and cold temperatures to replicate the temperature changes it would experience in real-world use. Thermal cycling can identify potential problems with seals and gaskets, solder joints, plastics, and other materials that could cause the product to fail. Products commonly tested using thermal cycling ESS include electronics, automotive parts, and medical devices.

 

Thermal cycles typically occur when:

  • A product is powered on and off in a controlled environment.
  • A product experiences slower outdoor temperature changes from morning until night.

 

The test conditions will vary depending on the item being tested. Typically they are performed in a chamber that controls the number of cycles, dwell times, transfer times, or ramp rates.

 

Thermal Shock Testing

This type of environmental stress screen goes beyond thermal cycling. Thermal shock and cycling testing both expose products to extreme temperatures. However, the transition from one to the other is accelerated with shock testing.

 

Thermal shock can occur when:

  • A product is transferred from an inside temperature-controlled environment to extreme outside temperatures. 
  • Turning on equipment that has been stored outside in extreme arctic-like temperatures.
  • Equipment experiences abrupt or significant changes in internal power.
  • A product is transported from a high-temperature ground environment to a high-altitude environment. 

 

Thermal shock testing can be done in two ways. It is typically performed in a dual compartment chamber, with one compartment for hot temperatures and the other for cold. Products sit in a carriage that shuttles them between the hot and cold compartments within seconds, causing the product to experience thermal shock. When testing larger items, a single compartment chamber capable of performing rapid temperature changes is used. 

 

Vibration Testing

 

Vibration testing is a type of environmental stress screening used to test products for potential problems that could lead to failures during normal use. Vibration testing subjects products to extreme vibrations to find flaws that could go undetected during normal operation. This helps to ensure that products are of the highest quality possible before being released to the public. 

 

Vibration testing is commonly used on electronic devices, electrical components, and mechanical parts. By subjecting these products to extreme vibrations, manufacturers can find potential problems that could lead to failures during normal use.

 

Vibration damage can occur from:

  • Vibration and shock stress during shipping.
  • Mechanical stress from application and usage throughout the product’s lifespan.

 

Environmental stress screening for vibration requires temperature testing, electrodynamic vibration testing, or both. The product being tested is placed in an environmental chamber and monitored while experiencing vibrations, temperature changes, and other stimuli. Vibration testing is used to reveal weaknesses or defects in the product’s construction.
