Understanding Physical Testing and Its Role in Quality Control

The term "physical testing" covers a range of tests that ensure different materials meet a certain standard. Depending on your industry, you may require access to electrical tests, fungal resistance tests or corrosion tests.

Because there are many factors at play during material production, physical testing helps ensure that everything has gone as intended. Physical tests protect you, your clients and their customers. They enhance your reputation as a company that can be trusted to keep its clients' best interests at the forefront of production.

The Importance of Physical Testing in Quality Control

Many modern industrial processes are automated and performed quickly. If there's an issue with machinery or a product specification, your company may not discover the issue right away. While some product defects are obvious, others aren't visual. Down the line, they can impact performance.

One of the most important roles of physical testing is to identify and rectify manufacturing defects before they have a significant impact on clients or your company. With physical testing in place, you can have confidence in your products because they are all tested before being sold.

The Impact of Physical Testing on Commercial Business Operations

Physical testing can be rolled into your product development and design flow. This ensures all products are appropriately tested without taking additional time after development. While testing does require time and equipment, it can save you time and finances in the long run.

Impact of appropriate testing operations

Every business owner understands the value of risk mitigation. By preventing issues with physical testing processes, you can lessen the risk of legal allegations, broken business relationships and loss of reputation. Physical testing is absolutely essential for a well-managed company.

Effective Strategies for Overcoming Physical Testing Challenges in Manufacturing

While it may be important, physical testing comes with its own set of challenges. Testing equipment must be reliable to give accurate measurements and test results. Some types of tests can take a long time, slowing down production.

Thankfully, technological advancements have made the physical testing process much easier. As equipment has become more reliable and accurate, the testing process has become faster and more stable. By investing in the proper testing equipment, you can make this process painless and easy.

  • Automotive: Plastics, polymers and petroleum
  • Chemical: Chemicals and packaging
  • Manufacturing: Food, metals and raw materials
  • Military: Nanomaterials, chemicals and packaging

Over time, modern manufacturing processes have become mostly or even fully automated. With fewer people working in manufacturing, it's important to ensure there's a way to catch mistakes during the production process.

Without physical testing, industries wouldn't be able to provide products to customers with a high level of confidence. Physical tests function both to improve workflows and to ensure current methods are reaching the high standards of each company.

Comprehensive Material Analysis at VTEC Laboratory

Physical testing encompasses a wide range of analyses for many different kinds of materials. Your intended use of the material will determine what kinds of physical tests you need to perform. For example, materials for an engineering project might need to be tested for electrical, weathering and mechanical properties.

VTEC professional testing lab offers testing procedures for an extensive list of materials, including the following:

  • Building materials
  • Composites
  • Chemicals
  • Food
  • Laminates
  • Metals and alloys
  • Nanomaterials
  • Packaging
  • Plastics
  • Petroleum
  • Polymers and resins
  • Raw materials
  • Structural materials

The specific testing procedures necessary for each material depend on the product's final use.

Corrosion and Immersion Testing

The corrosion resistance of a material plays an important role in how long it lasts, especially under harsh conditions. We conduct many different tests related to a material's resistance to corrosion and immersion. Some of the physical testing standards we provide for corrosion and immersion include:

  • ASTM B117 - Salt Spray Test - ASTM B117 uses a salt spray apparatus to test the corrosion resistance of metals and coated metals. We perform the test in a chamber and use a salt fog to produce a corrosive environment. It is often used in conjunction with other exposure tests to corroborate the results.
  • ASTM D4541 - Pull-off strength of coatings using portable adhesion-testers - This test determines the pull-off strength test, commonly referred to as adhesion, for coating systems on metal substrates. It uses portable adhesion-testers that apply a concentric load and counter load to a given surface. With this test, you can measure the greatest perpendicular force that a surface can withstand or determine whether a coated surface will stay intact at certain load criteria. This test will cause a fracture to occur along the weakest plane.
  • ASTM E96 - Water vapor transmission - This examination tests the amount of water vapor that will transmit through permeable and semipermeable materials in given conditions. We test the material in conditions closest to those it will be used in. You can conduct E96 by applying water to one side of a surface or by creating conditions with low humidity on one side and high humidity on the other.

Corrosion and Immersion testing

Some other physical testing standards we conduct in this area include:

  • ASTM C800: Water repellency (11.8)
  • ASTM C1016: Water absorption
  • ASTM C1363 exclude: Water absorption
  • ASTM D570: Water absorption
  • ASTM E859: Air erosion of sprayed fire-resistive materials applied to structural members
  • ASTM E937: Corrosion of steel by sprayed fire-resistive materials applied to structural members
  • ASTM G8: Test methods for cathodic disbonding of pipeline coatings
  • ASTM G12: Nondestructive measurement of film thickness of pipeline coatings on steel

  • ASTM G42: Test methods for cathodic disbonding of pipeline coatings subjected to elevated temps
  • ASTM G62: Holiday detection in pipeline coatings
  • MIL C-24643 Fluid immersion: JP5, Hydraulic fluids, etc.

Elemental Analysis and Testing

To determine what makes up a substance at a microscopic level, you need to run elemental analysis tests. At VTEC, we offer several tests that empower you to understand your products on an elemental level:

  • EDS: Energy-dispersive X-ray spectroscopy (EDS) involves applying a high-energy beam of charged particles to a sample, which will excite the atoms within the material. This causes energy to be released as an X-ray, which an energy-dispersive spectrometer measures. By analyzing the energies of the X-rays, you can determine the elements that make up the sample.
  • XRF: Another X-ray method for the identification and quantification of elements in a sample is X-ray fluorescence spectrometry (XRF). Applying high-energy X-rays or gamma rays excites a material and causes it to emit fluorescent, or secondary, X-rays. You can use these to perform elemental and chemical analyses. It is often used for testing metals, building materials, glass and ceramics, as well as for research.
  • XRD: X-ray diffraction analysis (XRD) is used primarily for evaluating the molecular and atomic structures of crystals. In this test method, also called X-ray crystallography, the X-rays caused by the high-energy beam bounce back in many different directions because of the crystalline structures of the material. Analyzing the ways in which the rays diffract enables the crystallographer to determine the density of the electrons in the crystal and determine the positions of the crystal's atoms, their chemical bonds and other characteristics.

We can also perform a variety of other elemental analyses, including:

  • ASTM D3171: This test determines the content of a composite material, such as the fiber content of resin-matrix composites using matrix digestion.
  • Atomic absorption spectroscopy: This test is a spectroanalytical procedure for detecting the levels of chemical elements in a sample in parts per million.
  • Electron microscopy: This analysis looks at materials using an electron microscope, which can determine levels of heavy metals and organic complexes.
  • Infrared spectroscopy analysis: This test offers an analysis of organic material using infrared spectroscopy.

Water Exposure, Weathering and Environmental Exposure Testing Standards

How products react to weathering and other environmental impacts is important information. It determines how long the materials used will last and, sometimes, whether they can perform their intended functions properly.

Below are some of the tests related to water exposure, weathering and environmental exposure that we most frequently conduct:

  • ASTM D523: This test measures the specular gloss of nonmetallic specimens. We obtain the gloss rating by comparing the reflectance of the material in question to that of a black glass standard. The test results will correlate with visual observations of shine from the same angles. D523 can also assess other characteristics such as reflection haze, the distinctness of reflected images and texture.
  • ASTM D570: Using this test method, we can measure the rate of water absorption of plastics. If you have determined how water will impact a product, you can use the rate of water absorption to determine how it will perform if exposed to water or moisture. You can also use it as a control test for the uniformity of sheet, rod and tube arms on a finished product.
  • ASTM G154: This test establishes standard practices for using a fluorescent ultraviolet (UV) lamp to test how a nonmetallic material reacts to exposure to UV light. Using this apparatus is meant to simulate the effects of typical everyday exposure. It can also replicate the impacts of sunlight through a window. Also known as the QUV test, G154 replaces ASTM G53.

Other environmental exposure tests we perform include:

  • ASTM B117: Salt water exposure
  • ASTM C473: Environmental exposure
  • ASTM D573: Accelerated aging of rubber in an air oven

For some materials, especially those used in environments that promote mold growth, resistance to mold is crucial for product life and proper performance. We offer the following product testing services for measuring fungal resistance:

  • ASTM D3273: This test measures resistance to mold growth on the surface of interior coatings, such as paint films, using an environmental chamber. It allows you to determine within a four-week period the relative resistance of these coatings to mold and mildew. It is useful for assessing a product's resistance to fungi growth, its performance under mold-promoting conditions and the compounds that can slow fungi growth.
  • ASTM G21: This test enables you to measure the resistance of synthetic polymeric materials to fungi and determine the effects of fungi on such materials. Synthetic polymers themselves are usually relatively resistant to fungi, so it is often the other components, such as colorants, cellulosics, stabilizers and lubricants that create the vulnerabilities. This test can help you choose which of these components to use.

Other fungal resistance tests we offer include:

  • ASTM D2017: Accelerated wood decay
  • ASTM D2020: Mildew (fungal) resistance of paper and paperboard
  • ASTM G22: Resistance to bacteria

Physical Testing Standards for Luminance Testing

Lighting is often critical to safety, so it is important to perform luminance tests on photoluminescent products. We can also conduct numerous luminescence tests:

  • ISO 15370: The ISO 15370 standard from the International Organization for Standardization sets requirements for the approval, installation and maintenance of low-location lighting systems on passenger ships, as defined by the International Convention for the Safety of Life at Sea and the IMO International Code for Fire Safety Systems.
  • ISO 17398: This test is a specification for safety colors and safety signs regarding classification, performance, durability and expected service life.
