After determining weak points in product design through efficient HALT methods, engineers can turn to additional testing strategies to figure out the extent of these components’ overall durability. Test XA and guidance: Immersion in cleaning solvents, Environmental testing – Part 2: Tests. Test Ec: Drop and topple, primarily for equipment-type specimens, Environmental testing. In addition to HALT, MET also provides full turnkey in-house solutions, including CAD test fixture designs, material procurement and machining services. The question comes down to which of the two methods is better for your particular product. 1. Test Z/AM: Combined cold/low air pressure tests, Environmental testing – Part 2: Tests. Test Ga: Acceleration, steady state, Environmental testing – Part 2: Tests. Here are a few key benefits to keep in mind when weighing different testing options: HALT can be an excellent first step in your overall product testing timeline. Part 2: Tests. The two methods accomplish different objectives, and they can both be highly beneficial when you work with the right testing service. Contact Quality Testing Services to Discover Which Testing Method Is Better for Your Product, HALT is all about discovering the causes of failures, The transportation and automotive industries, Industries that provide consumer products, HALT/HASS Testing Services from Quality Testing Services, How the HALT/HASS Testing Procedure Works, Establishing trial environments for the product within a controlled test chamber that expert technicians carefully monitor, Perpetually increasing stress factors such as temperature fluctuations to induce a sequence of failures, Testing limitations involving multiple stresses at once, including thermal variations, shocks, vibrations and other impacts, Revealing the causes of sudden malfunctions and measuring the product’s thresholds for cold and heat tolerance, Noting the product’s destruct limits, indicated by the failures after which the product can no longer be recovered, Increasing the occurrence of a typical product function to identify how many incidents are possible before failure, Comparing three different stress levels, including low, medium and high, between a determined number of product samples, Evaluating the relationship between stressed or accelerated variables and product failure time, using various stress-test models, Discovering the failure times of even the most reliable design components, Determining the settings and factors that will maximize the product’s lifetime.

MET Labs is a service leader and trusted provider of product testing and regulatory certification of electrical products for leading brands and companies in the United States, Europe and worldwide. Sampling Procedures and Tables for Inspection by Attributes. ALT and other forms of lifecycle testing perhaps offer a broader range of uses than more nuanced tests, as nearly every product on the market has a determinable lifetime. We believe the satisfaction of your customers and the reputation of your company are worth protecting. ALT can be effective on its own or in tandem with HALT testing methods for a more substantial overview. The NRTL mark is required under federal law for products used in workplaces in all 50 states. Accelerating the lifecycle of a product brings the following benefits to the table: Manufacturers across the board can benefit from lifecycle testing in whatever form it comes, but ALT especially offers these advantages at highly impressive rates. Test Ed: Free fall, Environmental testing – Part 2: Tests. Highly accelerated life testing also uses multi-axis shock vibrations that greatly reduce testing time while remaining accurate on artificially inducing real-time stressors. HALT testing is primarily used during the product design phase to reveal any defects and make the product more rugged and reliable. Highly Accelerated Life Testing (HALT): This testing process implements aggressive temperature and humidity rate changes. Part 1: General and guidance, Environmental testing – Part 2-1: Tests – Test A: Cold, Environmental testing – Part 2-2: Tests – Test B: Dry heat, Environmental testing – Part 2: Tests. The MET Mark for product safety is accepted throughout the United States & Canada and indicates compliance to federal regulations for safe use in the workplace. Test Ee and guidance: Bounce, Environmental testing – Part 2-57: Tests – Test Ff: Vibration – Time-history method, Environmental testing – Part 2-58: Tests – Test Td: Test methods for solderability, resistance to dissolution of metallization and to soldering heat of surface mounting devices (SMD), Environmental testing. With the two acronyms sharing three letters, it’s no wonder there’s some confusion surrounding the differences between HALT and ALT procedures. There are some fields of interest, however, including the ones listed as HALT industries, that can benefit substantially when undergoing ALT testing techniques. Part 2: Tests. While the HALT process can’t accurately determine the reliability of a product or how long it will last, it can help manufacturers and engineers see what kind of tweaks will improve the item’s durability. These steps are: 1. Part 2: Tests. Preparing for the HALT 3. Utilizing the two most common testing stimuli, temperature and vibration, it can precipitate failure modes faster than traditional testing approaches. There?s no specific HALT standard because it depends on the device characteristics.
