Accurate Measurement of Permanent DeformationDesigned for compliance with internationally recognized testing standards, this Compression Set Apparatus provides reliable and repeatable readings of compression set in rubber and elastomer materials. The polished, rust-protected plates ensure precise parallelism and sample integrity, while the high precision dial gauge delivers results down to 0.01 mm.
Engineered for Versatility and DurabilityConstructed from high-quality, rigid steel with a distinct blue or chrome finish, the apparatus offers exceptional durability and corrosion resistance. Its manual operation requires no power, making it suitable for laboratory or quality control environments where mobility and low maintenance are important.
Comprehensive Testing Accessories IncludedEach unit comes complete with a set of spacers and sample punches, accommodating standard specimen sizes required by ASTM D395. The apparatus is also supplied with a calibration certificate, supporting accurate and traceable measurement for routine and certification testing alike.
FAQs of Compression Set Appartus:
Q: How does the Compression Set Apparatus measure permanent deformation in rubber specimens?
A: The Compression Set Apparatus applies a controlled manual load to a rubber or elastomer specimen using parallel plates. After a specified period under compression, the device uses a high-sensitivity dial gauge to measure the residual thickness, indicating the permanent deformation remaining in the specimen after the fixed compression is removed.
Q: What test standards does this apparatus conform to?
A: This device is designed to meet the requirements of ASTM D395, IS 3400 (Part 10), and ISO 815, ensuring compatibility with international protocols for measuring compression set in rubber and related materials.
Q: When should I calibrate the Compression Set Apparatus?
A: The apparatus is supplied with a calibration certificate upon delivery. For continued accuracy, it is advisable to recalibrate according to your laboratorys schedule, prior to critical testing, or after any maintenance or adjustments.
Q: Where is the Compression Set Apparatus commonly used?
A: It is widely utilized in rubber fabrication plants, polymer research labs, quality control departments, and specialist materials testing institutes. It is suitable for use by manufacturers, suppliers, exporters, and other stakeholders in the rubber and polymer industries.
Q: What is the process for operating the Compression Set Apparatus?
A: Place the prepared sample between the polished plates using the spacers provided, then manually apply the load via the screw mechanism. After the prescribed compressive period, release the load and measure the final sample thickness using the analog dial gauge.
Q: What are the key benefits of using this apparatus?
A: The device delivers high precision results, offers robust corrosion resistance, and has a compact, manual design for ease of use and minimal maintenance, making it a cost-effective tool for both routine testing and research applications.
Q: How do I ensure accurate usage of the apparatus during tests?
A: Ensure the sample is of the correct standard size, the plates are properly aligned using the parallelism adjustment, and the dial gauge is zeroed before each test. Always follow the relevant test standard procedures for optimal accuracy.
