EN 1917:2002/AC:2008 (E/F/D) 4 In Annex J, Step 8 shall be as follows ("Table H.4" and not "Table H.3"):
Step 8: Determine the acceptability as follows:
Consider the measured value x of the bending tensile stress at the ultimate (collapse) load Fu from the last n consecutive samples.
Calculate the mean value xand the standard deviation s of these n values.
Calculate the lower quality statistic Q for the lower specification limit:
Q = (x - fdes)/s
where
fdes
is the lower specification limit for the bending tensile stress,
then compare the quality statistic with the acceptability constant k obtained from the appropriate column in Table H.4. Interpolation for intermediate values of n is permissible. For acceptance, the quality statistic for the lower specification limit shall be greater than or equal to the acceptability constant.

"Reinforced concrete units that have been tested only to proof (crack) load in accordance with 6.4 or 6.5 and meeting the requirements of 5.2.3 or 5.2.4 as appropriate conform to this European Standard."
6.1 General
Footnote a shall be changed as follows:

6.8 Concrete strength in base units, capping unit walls, adjusting units and certain tapers
Correct the conversion factor for drilled 50 mm ± 1 mm diameter cores from 0,9 into 1,07:
"Tests shall be carried out on drilled cores with a height equal to their diameter ± 10 mm:
 when 100 mm ± 1 mm diameter cores are used, the result shall be applied without any conversion factor;
 when 50 mm ± 1 mm diameter cores are used, a conversion factor of 1,07 shall be applied to the results."
Annex B: B.2 Apparatus
Add requirements on application of test load and accuracy of testing machine in accordance with those that apply for the crushing test on chamber and shaft units and specify the dimensions of the steel or cast iron plates. Replace the first sentence as follows:
"The apparatus shall consist of a testing machine capable of applying the full test load without shock or impact and with an accuracy of 3 % of the specified test load. The apparatus shall be equipped with steel or cast iron plates, through which the specified load is applied to the unit whilst it is supported around its perimeter. The dimensions of the steel or cast iron plate shall not exceed more than 125 mm the dimensions of the access opening. The width of beddings in contact with the unit shall correspond to the conditions that would be achieved in the structure for which the unit was designed."

EN 1917:2002/AC:2008 (E/F/D) 9 Annex C: C.7.2 Watertightness during angular deflection
Clarify the procedure for preventing the joint gap from closing by deleting the word "mean" in the 3rd sentence:
"The connecting pipe(s) or adaptor(s) shall be deflected to an angular deflection of 12 500/DN (or 12 500/WN, as appropriate to the shape of the bore of the connecting pipe(s) or adaptor(s)) in millimetres per metre or 50 millimetres per metre, whichever is the smaller, taking care to ensure that no structural damage is caused. In the case of an egg-shaped connecting pipe or adaptor the deflection shall be in the vertical plane. During this operation the joint gap(s) shall be prevented from closing at any point by, for example, interposing at the appropriate place(s) a packing with a thickness equal to the [ ] value of the clearance stated in the factory documents."
Annex C: C.7.3: Watertightness under shear load
Take into account that the pipe submitted to the watertightness test is not necessary completely filled with water: Add after the formula for Rs and the definition of Ww:
"Where the pipe is completely filled with water the value of Rs shall be calculated according to the following formula:
Rs = (Fs - Ww / 2) × l1 /( l1 - as) ≥ 0, in kilonewtons
where
Ww is the weight of one unit filled with water, in kilonewtons
Where the full length of the pipe barrel is not filled with water the formula shall be adjusted accordingly."
Annex D: D.4.1 Determination of mass of immersed sample m1
Clarify the procedure of immerging the sample, by inserting the word "minimum" to the 2nd sentence:
"The sample shall be brought to a temperature of 20 °C ± 3 °C, then immersed in tap water at the same temperature until a constant mass has been reached. This shall be achieved in stages by successively immersing the sample at intervals of one hour to approximately 1/3 of the height, approximately 2/3 of the height and the total height, with a minimum final water level of 20 mm above the top surface of the sample."
Annex G: Table G.1 :
Correct sampling procedures for concrete cover according to clauses 5.2.2: - by replacing the frequency 1 N for the initial type test by 1 S; - by adding the word "using" before "covermeter" for the initial type test; - by replacing the reference to 5.2.3 and 5.2.4 by the word "collapse" for the routine inspection."
Table G.1 — Sampling procedures Clause Test when specified Initial type test Routine inspection 5.2.2
Concrete cover 1 S using every unit that has been type-tested to 5.2.3 or 5.2.4, or using covermeter for other units Every unit that has been tested to collapse and, using convermeter, 2 N/day

6.1 Généralités
Précisez sous la note a du Tableau 5 que la résistance des carottes tirées des parois des éléments de couronnement est aussi sujet à des essais de type initiaux et de surveillance continue, même si la conformité des éléments de couronnement est vérifiée par un contrôle continu des performances:

6.8 Résistance du béton des éléments de fond, éléments de couronnement, rehausses sous cadre et certaines têtes tronconiques Précisez que la résistance à la compression du béton des éléments de couronnement doit être déterminée sur des échantillons prélevés dans les parois de ces éléments:
"La résistance à la compression du béton doit être déterminée conformément à l'EN 12390-3. L'essai doit être réalisé sur des échantillons prélevés par carottage aux tiers de la hauteur intérieure des éléments de fond, des parois des éléments de couronnement et des têtes tronconiques comme prescrit au Tableau 5 (soit deux échantillons par élément), ainsi qu'à chaque quart de la circonférence ou du périmètre des rehausses sous cadre. On calcule ensuite à chaque fois la valeur moyenne des résultats."
Changez le coefficient de conversion pour les carottes d'un diamètre de (50
± 1) mm d de 0,9 à 1,07:
"La hauteur des carottes doit être égale à leur diamètre ± 10 mm :
 lorsqu'on utilise des carottes d'un diamètre de (100 ± 1) mm, le résultat doit être exploité sans coefficient de conversion ;
 lorsqu'on utilise des carottes d'un diamètre de (50 ± 1) mm, on doit appliquer un coefficient de conversion
