ECSS-Q-40-04A (PART 1), SPACE PRODUCT ASSURANCE: SNEAK ANALYSIS - PART 1: METHOD AND PROCEDURE (14 OCT 1997)., The aim of Sneak Analysis is to identify "sneak circuits", i.e. unexpected paths for a flow of mass, energy, data or logical sequence that under certain conditions can initiate an undesired function or inhibit a desired function. Sneak circuits are not the result of failure, but are latent conditions, inadvertently designed into the system. This standard establishes a procedure for performing sneak analysis and specifies the required output. The standard is composed of two parts: part 1 (i.e. this document ECSS-Q-40-04 Part 1 "Sneak analysis - Part 1: Method and procedure") that contains the method and procedure for performing sneak analysis; D part 2 (i.e. the document ECSS-Q-40-04 Part 2 "Sneak analysis - Part 2: Clue list") that contains a basic clue list to be used during sneak analysis.
