 \chapter{Introduction}\label{cha:intro}
-The standards ISO~7637, \emph{Road vehicles -- Electrical disturbances from conduction and coupling}, and ISO~16750, \emph{Road vehicles -- Environmental conditions and testing for electrical and electronic equipment}, are international standards that apply to equipment in road vehicles with a nominal supply voltage of \SI{12}{\volt} or \SI{24}{\volt}. The standards states, here put in a very condensed form, that the product shall withstand a sufficient amount of disturbances applied to its power supply. The reason for this is that there can be voltage surges and noise in a vehicle's power supply lines. In general, the source of disturbances and noise in a vehicle origins from inductance in other devices connected to the power line, the cables and the vehicles alternator in combination with switching of loads or the supply. \cite{iso_7637_2, iso_16750_2}

 To test if a product comply with this standard, there is equipment that simulates different events on the power supply. The test events consists of voltage pulses that are applied to the DUT, device under test. The pulses of interest in this paper are denoted pulse 1, pulse 2a, pulse 3a, pulse 3b and load dump test A. The standard defines the different scenarios, raise and fall times of test pulses, repetition times etc. It also defines the functional requirements of the equipment during these tests for what is considered a passed or a failed test. \cite{iso_7637_2, iso_16750_2}

 This paper only considers Pulse 1, Pulse 2a, Pulse 3a, Pulse 3b and Load dump A. The main reason being that these are the pulses that the available equipment can generate, but also that these pulses share many properties and the method of analysing them will probably be very similar.

 \section{Previous research}
-No previous research relevant to the reuse of test equipment was found. Though there is research available on smaller specific topics that are covered by this project, such as measurement techniques and curve fitting. Those findings are presented in this theory chapter.

 \section{ISO standards}
 The ISO organisation, International Organization for Standardization, was founded in 1947 and has since published more than 22,500 International Standards. ISO standards does not only cover the electronic industry, but almost every industry. The purpose of the standards is to ensure safety, reliability and quality of products in a unified way, making international trade easier. The name ISO comes from the Greek word \emph{isos}, which means \emph{equal}.
 \cite{site:iso_about}
 
-A standard is developed and maintained by a Technical Committee, TC, consisting of, amongst others, experts in the area that the standard concerns \cite{site:iso_who_develops_standards}. A new standard is only developed when there exists a need for this from the industry or other groups that may require it \cite{site:iso_developing_standards}. Existing standards are automatically scheduled for review five years after its last publication, but can manually be reviewed before that time by the committee \cite{iso_guidance_review}. During the review process, it will be decided if the standard is still valid, need to be updated or if it should be removed \cite{iso_guidance_review}.

-The naming convention used for ISO standards is in the format \emph{number-part:year}, where the \emph{number} is the identifier to the unique ISO standard, \emph{part} denotes the part of the standard if it is divided into several parts and \emph{year} is the publishing year. For example, the name \emph{ISO~7637-2:2011} refers to part 2 of the ISO~7637 standard published in 2011, whilst \emph{ISO~7637-2:2004} would refer to an earlier version of the exact same document published in 2004.
