This Document provides a suggested maximum impurity level for silane (SiH₄) that is used in the photovoltaic industry.

This Document refers to an "as supplied" product; not point of use. Its quality is determined in a gaseous phase, at a delivery point agreed between the supplier and user, unless specified as a solid "deposited layer" derived from the gaseous source.

This Document is a guide and complete analytical methods are not contained within. Some of the available techniques for measuring impurities are shown in § 7.
