Table 2. Component-Level Standards
The standards that apply directly to isolation components are those of Table 2. The standards of Table 1 apply to applications that use isolation components. The designer of such an application must assure that the appropriate isolation component is selected such that compliance with the relevant application-level standard is ensured. However, the application-level standard is not directly applicable to the isolation component. Only the standards of Table 2 are imposed directly at the component level.
