Definition 38.34.10. Let $T$ be an affine scheme. A standard h covering of $T$ is a family $\{ f_ i : T_ i \to T\} _{i = 1, \ldots , n}$ with each $T_ i$ affine, with $f_ i$ of finite presentation satisfying either of the following equivalent conditions: (1) $\{ U_ i \to U\}$ can be refined by a standard ph covering or (2) $\{ U_ i \to U\}$ is a V covering.
