Testing Categories in Test & Measurement
Interface, Inc.
The World Leader in Force Measurement Solutions since 1968. The most accurate load cells, torque sensors + strain gages.
In the field of test and measurement (T&M), there are several categories of testing that are commonly used by metrologists, engineers and testing lab professionals. Interface is a supplier of different sensor technologies and supporting instrumentation that are used for a wide range of tests, from fatigue testing to structural tests.
The categories of testing are not mutually exclusive. In fact, multiple types of tests may be performed in combination to comprehensively evaluate components, products, and systems. Tests may also be based on the stages of a product or systems development. Other tests may be checks to ensure that the equipment or devices are operating as designed.
With certainty, the specific testing requirements will always depend on the industry use case, product or system characteristics, and desired quality, along with regulatory and performance standards. Learn more in our Types Of Force Measurement Tests 101 post.
Interface supplies thousands of various products to T&M labs and professionals across various industries, including medical, energy, industrial automation, automotive, consumer goods, infrastructure and aerospace.
Top Testing Categories in T&M
These categories encompass diverse types of tests performed to assess materials, components, products, and systems.
Functional Testing: Functional testing involves evaluating a part, product or system's performance and functionality against specified requirements. It verifies that it performs as designed, functions correctly and meets the desired performance criteria.
Structural Testing: A structural test using force measurement devices provides quantitative data on the forces exerted on a structure, enabling engineers to make informed decisions regarding design optimization, material selection, load capacity assessment, and maintenance or retrofitting requirements.

Material Testing: Materials testing is used to determine the physical and mechanical properties of materials, such as metals, polymers, composites, and ceramics. Common material tests include tensile, compression, bending, and hardness testing. See Interface Solutions for Material Testing Engineers
Performance Testing: Performance testing focuses on assessing the performance characteristics of a part, product or system under specific conditions. It measures parameters such as speed, throughput, response time, efficiency, and resource usage to ensure all performance expectations are met.
Reliability Testing: Reliability testing aims to determine the durability, consistency and potential of the test article over an extended period. It involves subjecting the product or system to various stressors, such as hot temperatures, humidity, vibrations, or accelerated aging, to assess its durability and ability to withstand real-world operating conditions. These types of tests include cycling, temperature, and fatigue tests.
Environmental Testing: Environmental testing evaluates a test object's performance and resistance under different environmental conditions. It includes tests for temperature extremes, humidity, vibration, shock, dust, water resistance, and other environmental factors it may encounter during its lifecycle. These types of tests often require ruggedized testing devices to ensure they can withstand the same degree, pressure and exposure as the test object. This is also commonly used in ongoing performance tests when objects are submersed or exposed to harsh conditions. Interface offers a range of products designed for these types of extreme testing requirements.

Life Cycle Testing: Life cycle testing assesses the performance, reliability, and durability of a part, product or system throughout its expected lifespan. It involves subjecting the specimen to simulated or accelerated aging, repetitive stress testing, or long-duration tests to evaluate its performance over time.
Safety Testing: Safety testing focuses on assessing the safety features and compliance with relevant safety standards and regulations. It includes tests for electrical safety, mechanical safety, fire resistance, radiation safety, and other hazards specific to the industry or application.

Certification Testing: Certification testing involves obtaining certifications or compliance with industry-specific standards, regulations, or quality management systems. These tests are conducted to ensure that the product or system meets specific requirements set by regulatory bodies or industry organizations. This is important when introducing a new component to an existing environment or as part of a product.
Calibration and Metrology: Calibration testing involves verifying and adjusting measuring instruments or equipment to ensure accurate and reliable measurements. Metrology focuses on establishing measurement standards, methods, and traceability to ensure consistency and accuracy in industrial measurements. All testing devices used in force measurement must be calibrated and certified before use to ensure they meet the specifications of the design. Interface calibrates all load cells before they leave our factory. Lean about Interface’s range of calibration-grade load cells and calibration systems for these types of tests. We also provide calibration services and repair.
