2.ALUMINIUM HONEYCOMB CERTIFICATION
A complete testing procedure for certification of aluminium honeycomb is given in NHTSA TP-214D. The following is a summary
of the procedure that should be applied to materials for the frontal impact barrier, these materials having a crush strength
of 0,342 MPa and 1,711 MPa respectively.
2.1.Sample locations
To ensure uniformity of crush strength across the whole of the barrier face , eight samples shall be taken from four locations evenly
spaced across the honeycomb block. For a block to pass certification, seve n of these eight samples shall meet the crush strength
requirements of the following sections.
The location of the samples depends on the size of the honeycomb block. Firs t, four samples, each measuring 300 mm × 300 mm
× 50 mm thick shall be cut from the block of barrier face material. Please ref er to Figure 2 for an illustration of how to locate these
sections within the honeycomb block. Each of these larger samples shall be cut into samples for certification testing (150 mm ×
150mm×50mm).Certificationshallbebasedonthetestingoftwosamplesfr omeachofthesefourlocations.Theothertwoshould

2.2.Sample size
Samples of the following size shall be used for testing:
length: 150 m m±6m m ,
width: 150 m m±6m m ,
thickness: 50 m m±2m m .
The walls of incomplete cells around the edge of the sample shall be trimmed as follows:
— in the „W“ direction, the fringes shall be no greater than 1,8 mm (see Figur e 3);
— In the „L“ direction, half the length of one bonded cell wall (in the ribbon direction) shall be left at either end of the specimen
(see Figure 3).11/т. 42 BG Официален вестник на Европейския съюз 97
2.3.Area measurement
The length of the sample shall be measured in three locations, 12,7 mm from e ach end and in the middle, and recorded as L1, L2
andL3(Figure3).Inthesamemanner,thewidthshallbemeasuredandrecord edasW1,W2andW3(Figure3).Thesemeasurements

5.1. Thedeformablebarriershallberigidlyfixedtotheedgeofamassofno tlessthan7×104kgortosomestructureattachedthereto.
The attachment of the barrier face shall be such that the vehicle shall not c ontact any part of the structure more than 75 mm from
the top surface of the barrier (excluding the upper flange) during any stag e of the impact (1).
The front face of the surface to which the deformable barrier is attached sh all be flat and continuous over the height and width of
thefaceandshallbevertical±1°andperpendicular±1°totheaxisoftheru n-uptrack.Theattachmentsurfaceshallnotbedisplaced
by more than 10 mm during the test. If necessary, additional anchorage or ar resting devices shall be used to prevent displacement
of the concrete block. The edge of the deformable barrier shall be aligned w ith the edge of the concrete block appropriate for the
side of the vehicle to be tested.
(1) A mass, the end of which is between 125 mm and 925 mm high and at least 1000 mm d eep, is considered to satisfy this requirement.11/т. 42 BG Официален вестник на Европейския съюз 99
5.2. The deformable barrier shall be fixed to the concrete block by means of 10 bolts, five in the top mounting flange and five in the
bottom. These bolts shall be of at least 8 mm diameter. Steel clamping strip s shall be used for both the top and bottom mounting
flanges(seeFigures1and5).Thesestripsshallbe60mmhighand1000mmwid eandhaveathicknessofatleast3mm.Theedges
of the clamping strips should be rounded-off to prevent tearing of the barr ier against the strip during impact. The edge of the strip
should be located no more than 5 mm above the base of the upper barrier mounti ng flange, or 5 mm below the top of the lower
barrier-mounting flange. Five clearance holes of 9,5 mm diameter must be d rilled in both strips to correspond with those in the
mounting flange on the barrier (see paragraph 4). The mounting strip and ba rrier flange holes may be widened from 9,5 mm up to
a maximum of 25 mm in order to accommodate differences in back-plate arrang ements and/or load cell wall hole configurations.
None of the fixtures shall fail in the impact test. In the case where the defo rmable barrier is mounted on a load cell wall (LCW) it
should be noted that the above dimensional requirements for mountings are intended as a minimum. Where a LCW is present, the
