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
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
FMVSS 207 & FMVSS 210 Seat Belt Anchorage Testing: Why FAD1 and FAD2 Are Transforming Compliance Testing By Schap Specialty Machine, Inc. For automotive OEMs, Tier 1 seat manufacturers, and accredited automotive testing laboratories, demonstrating compliance with FMVSS 207 (Seating Systems) and FMVSS 210 (Seat Belt Assembly Anchorages) is one of the most critical structural
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
Compression Testing Foam with the Schap Specialty Machine Servo Universal Test Machine Why Compression Testing Matters Flexible polyurethane foam is engineered to deform under load while recovering its original shape when the load is removed. The ability to maintain these characteristics over thousands of loading cycles directly affects product quality. Compression testing helps manufacturers determine:
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
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
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,
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
Fogging Test Glass Plates: A Critical Consumable for Automotive Fog Testing When automotive interior materials are evaluated for fogging, the glass plate used in the test may appear to be a simple piece of laboratory glass. In reality, the fogging test plate is a precision test component and a critical part of the measurement system.
