Biomerics offers the following standard ISO/ANSI/AAMI/ASTM tests validated in a GLP(Good Laboratory Practice) environment:
| Test or Process | Description | Equipment | ASTM Standard |
| Hardness (Shore A/D) | Shore hardness is a measure of resistance of material to indentation by a durometer. | Check-Line HP Series Shore Durometers | D2240 |
| Tensile Strength (psi/MPa) | A measure of the ability of a material to withstand a longitudinal stress, expressed as stress/strain curve and ultimate tensile at break. | Testometric M350-5CT | D412, D638 |
| Elongation (%) | The percentage a material stretches or elongates to fail or break | Testometric M350-5CT | D412, D638 |
| Flexural Modulus (psi/MPa) | A measure of the stiffness of a material. | Testometric M350-5CT | D790 |
| Compression Set (%) | The permanent deformation a sample has after being compressed a stated amount (%) at a specific temperature for a given amount of time and recovery period. | Qualitest Compression Set Test Fixture |
D395 |
| Melt Flow Index | A measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a campilary of a specific diameter and length by a pressure applied via prescribed alternative gravimetric weights for alternative prescribed temperatures. | TMI XNR-400 Series Melt Flow Indexer | D1238 |
| Specific Gravity | The ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unity volume) of a reference substance. | Alfa Mirage Electronic Densimeter MD-3005 | D792 |
| Karl-Fischer Moister Analyzer | Coulometric KF determinations. |
Aquastar AQC34 |
In-house |
| Reactant Titrations | Determines the concentrations of a solution. Used to determine the OH number and NCO content of polyols and isocyantes, respectively. |
Mettler Toledo T50 | EI899, D5155 |
| Ash Testing | The amount of ash remaining after burning at high temperatures. Used for determining percentage content, such as percent barium in a material. | Carbolite AAF 110 | D5630 |
| DSC | A thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Used to analyze melting and crystallization peaks, and glass transitions. | TA Instruments DSC Q20 | TA Protocol |
