Norm Lambert the author of this page is a voting member of ASTM Technical Subcommittee C09.25 that sets the ASTM C881 standard. 5.1 This test method is used to obtain the resin flow of carbon fiber-epoxy prepreg tape or sheet material. The procedures of this test method are divided into the following parts: 1. ASTM D3531 – Resin Flow Testing. Independent testing and evaluation of ion exchange resins used for water treatment in nuclear and other industries. It has a simple 1:1 mix ratio (by weight), and is frequently used in applications requiring excellent thermal shock and mechanical shock resistance. Standard References. How it works Nutrients in the soil are in equilibrium with those in the soil solution, and plant roots, using an ion exchange mechanism, take up nutrients from the soil solution as required. Method of Test for Evaluating Epoxy Resin Systems at Low Temperatures by Flexural-Creep Measurements (Test method is withdrawn. Backwashing . Pressure sensitive tape is applied and removed over cuts made in the coating. Epoxies and resins are chemicals that can form a hard, strong surface when they cure. The careful selection of sand type, resin characteristics and coating method results in the desired mold and core properties such as strength, rigidity, flexibility, … The resin… Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard. When a standard test method exists, including those used in other fields, these have been identified in the beginning of each section. On metal substrates, a more formal version of the knife test is the tape test. Standard Test Method for Physical and Chemical Properties of Particulate Ion‐Exchange Resins D5627‐94 (R1999) 15‐NOV‐1994 Standard Test Method for Water Extractable Residue from Particulate Ion‐Exchange Resins D4266‐96 10‐JUL‐1996 Appendix A - Part 1 - Test Methods. Intertek polymer and plastics resin testing capabilities help clients worldwide with troubleshooting expertise, research, formulation, … D1544 Test Method for Color of Transparent Liquids (Gardner Color Scale) D1545 Test Method for Viscosity of Transparent Liquids by Bubble Time Method. Refer to contact for further information) Lisa Watson (916) 227-7291 [email protected] : 420 (PDF) February 1, 2014 The test is somewhat similar to the HWI test in that it measures a material’s resistance to ignition on application of a heated non-flaming source. 2.1 Differences in specific resin and suppressant additive chemistry affect the performance of a vapor suppressant. D 445 Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (the Calculation of Dynamic Viscos-ity)2 D 1209 Test Method for Color of Clear Liquids (Platinum-Cobalt Scale)3 D 1259 Test Methods for Nonvolatile Content of Resin Solutions4 D 1475 Test Method for Density of Liquid Coatings, Inks, and Related Products4 6.1 This test method covers the conversion of ion-exchange resins to a known ionic form and is intended for application to both new and used material. The initial step includes identifying the available standardized test methods and understanding the important differences between them. Ion exchange capacities by ASTM and other methods, Carbonate/bicarbonate content (including organically-bound and ionic C-14), Resin flow testing facilities (kinetics and operating capacity under once-through and recirculation modes for engineering scale-up projections), Slurriability and separability of mixed bed resins, Crush strength (friability – Chatillon) and attrition, Specialized sampling and analysis capabilities for radioactive process resins and waste resins, Quality assurance and quality control testing of new resins, Cleaning, defouling, conditioning of new and old resins including use of supercritical fluid-based techniques, Performance evaluation, optimization and testing including resin life for specific applications and conditions, Characterization of resin leachables and degradation products (including high molecular weight species, organo chlorines, and organo sulphur species), Filter media testing (flat sheet and cartridge), Cooling water corrosion and microbiologically-influenced corrosion (MIC), Preparation of product procurement specificaitons for new IX resins.
