FAQs of astm d892 foaming dynamic fatigue tester:
Q: How does the ASTM D892 Foaming Dynamic Fatigue Tester measure foam characteristics?
A: The tester dynamically agitates lubricant or foam specimens within a borosilicate glass cylinder and measures the resulting foam volume and collapse rate using precise digital sensors. Results are displayed in real-time on a digital LED screen, with data capture facilitated via RS232 or USB interfaces.
Q: What are the main benefits of using this foaming fatigue tester?
A: Key benefits include high measurement accuracy (0.5% of reading), rapid response time (<1 second), automatic control for programmable cycles, built-in safety features, and comprehensive data acquisition. This ensures dependable, repeatable results and helps laboratories streamline their testing workflow.
Q: When should I calibrate the instrument, and is recalibration required upon installation?
A: The instrument is factory calibrated and ready to use upon delivery. Routine calibration checks are recommended according to your facilitys quality management protocols or after extensive use to ensure continued accuracy. Instructions are provided in the included manual.
Q: Where is this instrument typically used, and who are the primary users?
A: This equipment is commonly found in industrial, research, and quality control laboratories focused on lubricants, foam products, or polymer materials. It is suitable for manufacturers, scientific researchers, suppliers, and technical service providers.
Q: What is the procedure for conducting a test with this apparatus?
A: Place the prepared specimen in the cylinder, select your test parameters using the digital controller, and initiate the cycle. The tester agitates the sample at 60 1 cycles/min, monitors foam production, and records results automatically. Data can be stored or exported via RS232/USB.
Q: How does the built-in safety system enhance operational safety?
A: The testers safety system includes overload and overheat protection alongside an emergency stop function. This design minimizes the risk of operator injury or equipment damage, providing secure operation even in demanding laboratory environments.
Q: What is the range of specimens and conditions the tester can accommodate?
A: The system supports 13 specimens at once, with a specimen size of 380 x 380 x 50 mm and a capacity of 20200 N. It operates at ambient temperatures up to 80C and under a humidity level 85% RH, allowing for flexible and robust testing scenarios.
