Describes procedures for on-site measurement of crystalline silicon photovoltaic (PV) array characteristics and for extrapolating these data to Standard Test Conditions (STC) or other selected temperatures and irradiance values.

Gives a method of test which provides a standard procedure to determine the ability of components, equipment and other articles to withstand specified severities of sinusoidal vibration. Has the status of a basic safety publication in accordance with IEC Guide 104. The contents of the corrigendum of March 1995 have been included in this copy.

Cancels and replaces the first edition (1987). Specifies procedures for the connectionless-mode transmission of data and protocol control information; procedures for the correct interpretation of transport protocol control information; the functional requirements for implementations claiming conformance to this standard; the encoding of the transport-protocol-data-units used for the transmission…
