What to Test: Sampling and Sample Preparation
In Chapter 3, the question of what to test was explored from the aspect of stage in the development process-that is, material, component, or device. In the chapters that follow, the primary concern will be issues of how to actually perform tests, which are explained in detail. But here the vital bridge between these is addressed-how to select actual individual items for testing (sampling) and how to prepare the items selected for the testing process (sample preparation). The International Organization for Standardization standard ISO 10993-12 addresses both these issues (and the selection and use of reference materials) in summary fashion.
