Preface
Euro NCAP contracts a number of different test laboratories in Europe to perform the official Euro NCAP tests. This Technical Bulletin describes how the test data should be acquired and supplied to Euro NCAP to ensure consistency throughout all laboratories.

TEST DATA
A complete Euro NCAP assessment consists of many tests. To ensure consistency in the general folder structure, this chapter details the required folder structure. For each (sub)test where measurements are performed on dummies, vehicles or other test equipment, all test data needs to be provided in ISO-MME 1.6 format and needs to be fully compliant with the ISO/TS 13499 standard. It should be noted that some filenames are also prescribed in this document.
1.1
General folder structure
The following structure is to be used for all test series where the name of the main folder containing all tests consists of: The year of test - - OEM abbreviation - Euro NCAP internal number Make and Model - Where Euro NCAP tests contain a number of sub-tests, the next paragraph details the folder structure, names of the sub-system test folders and where applicable the filenames. On the highest level, the folder structure is as follows with on the right an example using the Volvo XC90 that is assumed to be tested in 2016 with a Euro NCAP internal number of 999.

Whiplash sub-test folders
The Whiplash test folder contains 4 sub-test folders. Three contain the dynamic data from the three dynamic pulses tested; Low, Medium and High. In addition, the rear whiplash data is contained in a separate folder. The static measurement file and whiplash test report will be filed in the main Whiplash folder.

For each of these pedestrian tests there will be a separate sub-test folder (e.g. A10-5 folder), which needs to contain the channel and picture folders and the MME-file. The test numbers for each subtest consists of the Euro NCAP test number followed by the GRID point label. The test report in the main report folder should contain all plots of all tests combined in one file. called (16-VOL-999-PP).

INJURY CRITERIA CALCULATION
This chapter describes the calculation for each injury criteria used within Euro NCAP, including the filters that are applied to each channel used in these calculations. The analysis software used by the Euro NCAP labs will follow these calculations in detail. For all of the calculations and for all of the dummies used, only the loading phase of the crash is considered. The loading phase for all dummies in the frontal tests will end at the point in time where the Filtered Head Acceleration A x crosses 0 after the minimum acceleration peak value.
