Gravimetric vs. Reflectometric Fog Testing: Which Method Should You Use? One of the most common questions asked by automotive materials engineers and laboratory managers is: "Should our laboratory perform gravimetric fog testing or reflectometric fog testing?" The answer is often both—but for different reasons. While each method evaluates the tendency of automotive interior materials to
Why Repeatability Matters More Than Accuracy in Material Testing Consistency is the foundation of meaningful test data. In every material testing laboratory, one question ultimately determines the value of the data collected: Can the test be repeated and produce the same results? While equipment accuracy is certainly important, the ability of a testing system to
The History of DIDP (Diisodecyl Phthalate) as the Industry Reference Material for Automotive VOC Fog Testing Why One Plasticizer Became the Industry Benchmark—Despite Its Known Variability In automotive interior materials testing, few reference materials have been used as consistently as Diisodecyl Phthalate (DIDP). For more than three decades, DIDP has served as the reference liquid
Fred Barwick: The Educator Who Helped Standardize Automotive Fog Testing How one industry expert helped laboratories around the world perform more accurate, repeatable, and reliable fogging tests. For today's automotive testing laboratories, fogging testing is simply part of doing business. Whether evaluating instrument panel materials, seat fabrics, adhesives, foams, coatings, or plastic trim, engineers routinely
Understanding Colorfastness Testing with the Schap Gakushin Tester How the JIS L0849 Standard Helps Ensure Durable, Fade-Resistant Textiles In today's automotive, aerospace, furniture, apparel, and technical textile industries, appearance is every bit as important as performance. Consumers expect fabrics to retain their original color throughout years of use—even after repeated rubbing, cleaning, and exposure to
How Schap Specialty Machine Built Upon the Hart Scientific Legacy Continuing the Evolution of Dry Fog Testing Few laboratory tests demand the level of thermal precision required for automotive fogging evaluations. Whether testing interior plastics, textiles, foams, adhesives, leather, or coatings, the reliability of the data ultimately depends on one critical factor: repeatability. Over the
One of the barriers to entering material testing in your lab is financing. With scarcity of limited resources, you are forced to have your testing done by outside, third-party services. You lose control over the process and have to trust someone else. At Schap, we understand business finances. That's why we offer alternatives. If you
DIN 75201 Explained: A Guide for Automotive Test Laboratories As automotive interiors continue to evolve with new polymers, adhesives, coatings, and sustainable materials, manufacturers face an ongoing challenge: ensuring these materials do not release excessive volatile compounds that can condense on interior glass surfaces. To address this concern, automotive manufacturers have adopted standardized fogging tests
Whole-Seat VOC Testing: The Next Evolution in Automotive Interior Emissions Testing? As automotive manufacturers continue to reduce volatile organic compound (VOC) emissions from vehicle interiors, testing methods are evolving to better reflect what consumers actually experience inside a completed vehicle. Traditionally, VOC and fogging evaluations have been performed on individual materials and components. Today, however,
Why Automotive Test Laboratories Choose Schap Specialty Machine for Cast Aluminum Butt and Back Forms The Foundation of Accurate Seat Testing Begins with the Right Test Forms In automotive seating validation, sophisticated test machines often receive most of the attention. Servo-hydraulic systems, programmable fatigue testers, and automated seat durability equipment are certainly impressive, but every
