Product Functional, Durability Tests

Product testing is a quality, dependability, and durability extremely important part of the development process. Quality means determining whether or not your product will perform as expected. Every product needs to test in a product testing laboratory to ensure that they meet quality standards.

Product durability testing aids in the improvement of your product and the generation of more income through client retention and happiness. Quality assurance and ensuring that all standards are met and rules are followed before distribution are two of the most critical parts of product testing.

The effect of fogging is created when gases of various volatile organic compounds, which can evaporate from trim materials in vehicle interiors, are condensed. Maeon Laboratory fogging testing lab in Chennai conducts tests such as DIN 75201, DIN 75201, ISO 6452, SAE J1756, and PV 3015.

Fogging is a common phenomenon that occurs in various products, such as car interiors, mirrors, eyeglasses, and other plastic products. To ensure product safety and quality, fogging testing labs perform a range of tests to measure the extent of fogging in products. These tests determine the number of volatile materials that evaporate from the product and whether they deposit onto surfaces in the form of fog.These tests are frequently specified by many OEM standards and International Standards and being carried out in the facilities of Maeon Laboratories. Some are detailed in the following listing for ready reference.

Product functional Testing that verifies that the product system meets the functional requirements. These forms of functional tests assist organizations in ensuring that digital goods meet requirements at all levels, from the code to the system as a whole.

Resistance Test

The polymer materials deteriorate upon exposure to high / low heat conditions and with varying humidity conditioning. Continuous and cycling tests to automotive specifications and other international specifications are conducted by Maeon Laboratories. These tests require high precision climatic chambers, Thermal cycle chamber, Humidity chambers, which is a part of facilities at Maeon Laboratories.

Thermal Shock Tests – Polymeric products and mateial

Thermal Shock Tests – Polymeric products and material.

Thermal shock testing, also known as temperature cycling or temperature shock testing, exposes products to alternating low and high air temperatures in order to speed up failures caused by repetitive temperature changes in regular use settings. This testing is required to recreate such conditions and to better understand product performance.During the thermal shock testing, products may be powered or unpowered. Cables that reach outside of the chamber and fit inside the chamber feed through are required for products that are powered during the test.

Very swift temperature changes affect polymer product material and thus affect the performance. Hence, thermal shock testing is specified to simulate such conditions and to understand the performance of the products.

The polymer materials deteriorate upon exposure to high / low heat conditions and with varying humidity conditioning. Continuous and cycling tests to automotive specifications and other international specifications are conducted by Maeon Laboratories.

Temperature cycling chambers are ideal for test applications that require quick change in temperature ramp rate such as 1°C and 5°C per minute or as required, which facilities are available at Maeon Laboratories.

Scratch Resistance

The surface of plastic, fabrics, leather pars, painted surfaces, printed parts can be visibly damaged in several ways, including scratching by a sharp object; abrasion by rubbing with an abrasive material; marring, which changes the surface appearance or gloss

A scratch is created when the material yields under an indentation force and a sliding or lateral force, resulting in ductile and/or brittle failure. In a scratch, the uneven surface results in non-uniform light scattering and "scratch whitening".

Scuffing Test

 
Mar resistance is a surface property, whereas scratch or abrasion resistance involves the body of the material as well. The extent of damage on the surface of the test material due to Wear, Mar, scratch resistance and scuffing are measured by rubbing at specified rate using specified abrasive surfaces. The common instrument is for the purpose is a Taber abrader and linear abrader. Maeon laboratories have test facility to perform Wear testing, Mar testing and Scratch testing

Pencil Hardness is a rapid, inexpensive determination of the film hardness of an organic coating on a substrate in terms of drawing leads or pencil leads of known hardness.

Yellowness Index

Yellowness index. Grey scale colour index etc. are numbers derived from spectrophotometric data that describes the change in color of a test sample from clear or white to yellow, on subjecting sample to ageing.

The test is used for the instrumental measurement of the degree of yellowness (or change of degree of yellowness) under daylight illumination of homogeneous, nearly-colorless transparent or nearly-white translucent or opaque plastics.

Fatique Tests and Durability Tests

Fatique testing is cyclic loading of a sample to understand how it will perform under similar conditions.

The behavior of the materials subjected to such repeated cyclic loading in Flexing Stretching Compressing Twisting studied by Fatique tests.

Repeated cyclic loading eventually constitutes a mechanical deterioration and progressive fracture that leads to complete failure, in Plastics, Rubber, Composite materials, fabric and other materials.

For many dynamic applications, it is necessary to generate fatigue data to demonstrate the long term durability of products. Polymeric materials are not only time and temperature dependent but are significantly affected by fluids which come into contact.
