Déanfaidh na bogearraí dinimiméadair ceithre luasmhoilliú saor-rothlaithe ar an iomlán.
The dynamometer software shall perform a total of four coastdowns.
#2617964
Tar éis an chéad luasmhoilliú saor-rothlaithe, déanfaidh na bogearraí trí luasmhoilliú saor-rothlaithe bhreise le comhéifeachtaí socraithe dinimiméadair sheasta arna gcinneadh tar éis an chéad luasmhoilliú saor-rothlaithe nó na comhéifeachtaí socraithe dinimiméadair coigeartaithe de réir mhír 8.1.4. den iarscríbhinn seo.
Following the first coastdown, the software shall perform three additional coastdowns with either the fixed dynamometer setting coefficients determined after the first coastdown or the adjusted dynamometer setting coefficients according to paragraph 8.1.4. of this annex.

Stopfar an tomhas tar éis dhá luasmhoilliú má tá fórsa an dá luasmhoilliú saor-rothlaithe ag gach pointe luais tagartha laistigh de ±10 N, nó sin feidhmeofar ar a laghad trí luasmhoilliú saor-rothlaithe ag úsáid na gcritéar a leagtar amach i mír 4.3.1.4.2. den iarscríbhinn seo.
The measurement shall be stopped after two decelerations if the force of both coastdowns at each reference speed point is within ±10 N, otherwise at least three coastdowns shall be performed using the criteria set out in paragraph 4.3.1.4.2. of this annex.

Roimh an luasmhoilliú saor-rothlaithe, déanfar an t-ainéimiméadar a chalabrú le haghaidh luais agus seach-chur luascála mar a shonraítear in ISO 10521-1:2006(E) Iarscríbhinn A.
Before the coastdown, the anemometer shall be calibrated for speed and yaw offset as specified in ISO 10521-1:2006(E) Annex A.

Mar mhalairt ar ualach friotaíochta bóthair a chinneadh leis an luasmhoilliú saor-rothlaithe nó modh méadair casmhóiminte, is féidir modh ríofa le haghaidh ualaigh friotaíochta bóthair réamhshocraithe a úsáid.
As an alternative for determining road load with the coastdown or torque meter method, a calculation method for default road load may be used.

Luasghéarófar an fheithicil ina dhiaidh sin go dtí 10 km/u ar a laghad os cionn an luais tagartha is airde agus tosófar an luasmhoilliú saor-rothlaithe láithreach.
The vehicle shall be subsequently accelerated to at least 10 km/h above the highest reference speed and the coastdown shall be started immediately.

Roimh gach luasmhoilliú saor-rothlaithe, tiomáinfear an fheithicil ag an luas tagartha is airde nó, sa chás go n-úsáidtear an nós imeachta téimh malartach ag 110 faoin gcéad den luas tagartha is airde, ar feadh 1 nóiméad ar a laghad.
Prior to each coastdown, the vehicle shall be driven at the highest reference speed or, in the case that the alternative warm-up procedure is used at 110 per cent of the highest reference speed, for at least 1 minute.

Arna iarraidh sin ag an monaróir agus le formheas an údaráis fhreagraigh, is féidir an t-am idir an nós imeachta téimh agus luasmhoillithe saor-rothlaithe ag úsáid an mhodha atriallaigh a shíneadh lena áirithiú go mbeidh an socrú ceart ar an bhfeithicil le haghaidh luasmhoilliú saor-rothlaithe.
At the request of the manufacturer and with approval of the responsible authority, the time between the warm-up procedure and coastdowns using the iterative method may be extended to ensure a proper vehicle setting for the coastdown.

Ón gcéad luasmhoilliú saor-rothlaithe, ríomhfar comhéifeachtaí socraithe an dinimiméadair le haghaidh an dara triail a ríomh de réir mhír 8.1.4. den iarscríbhinn seo.
From the first coastdown, the dynamometer setting coefficients for the second run shall be calculated according to paragraph 8.1.4. of this annex.

Beidh na fórsaí ríofa sna raonta luais sonraithe laistigh de ±10 N tar éis aischéimniú íoschearnóg na bhfórsaí le haghaidh dhá luasmhoilliú saor-rothlaithe leantacha i gcomparáid leis na spriocluachanna, nó feidhmeofar luasmhoillithe saor-rothlaithe breise tar éis socrú ualaigh raoin rollaigh a choigeartú de réir mhír 8.1.4. den iarscríbhinn seo go dtí go gcomhlíontar an lamháltas.
The calculated forces in the specified speed ranges shall either be within ±10 N after a least squares regression of the forces for two consecutive coastdowns when compared with the target values, or additional coastdowns shall be performed after adjusting the chassis dynamometer load setting according to paragraph 8.1.4. of this annex until the tolerance is satisfied.

Mura ndéanann an fheithicil luasmhoilliú saor-rothlaithe ar bhealach in-athdhéanta agus nach bhfuil modh luasmhoillithe saor-rothlaithe feithicle de réir mhír 4.2.1.8.5. den iarscríbhinn seo indéanta, ríomhfar na comhéifeachtaí, f0, f1 agus f2 sa chothromóid ualaigh friotaíochta bóthair ag úsáid na gcothromóidí i mír 8.2.4.1.1. den iarscríbhinn seo.
If the vehicle does not coast down in a repeatable manner and a vehicle coastdown mode according to paragraph 4.2.1.8.5. of this annex is not feasible, the coefficients f0, f1 and f2 in the road load equation shall be calculated using the equations in paragraph 8.2.4.1.1. of this annex.
