In Annex K, Step 8 shall be as follows ("Table I.4" and not "Table I.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 x and 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 I.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.
1 Scope
Add in the first sentence "for use in pipelines" after " . and reinforced, ":
"This European Standard specifies performance requirements as defined in Table 1 and describes test methods for precast concrete pipes and fittings, unreinforced, steel fibre and reinforced, for use in pipelines with flexible joints (with seals either integrated in the units or supplied separately) and nominal sizes not exceeding DN 1 750 for units with a circular bore or WN/HN 1 200/1 800 for units with an egg-shaped bore, for which the main intended use is the conveyance of sewage, rainwater and surface water under gravity or occasionally at low head of pressure, in pipelines that are generally buried."
3.1.8
add "pipe with inlet" to the definition of a fitting:
"fitting adaptor, bend, connecting pipe, junction, pipe with inlet or taper (reducer)"
5.2.4 Conformity of proof (crack) load tested pipes
Add the words "that have been" after "pipes" in the first sentence:
"Reinforced concrete pipes that have been tested only to proof (crack) load in accordance with 6.4 and meeting the requirements of 5.2.3 conform to this European Standard."
6.8 Concrete strength in jacking pipes
Correct the conversion factor for drilled 50 mm ± 1 mm diameter cores from 0,9 into 1,07:
EN 1916:2002/AC:2006 (E/F/D) 3 "The drilled cores shall have 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."
A.2.5.2.1 Preliminaries
Correct the formula for δmax:
"The specific force/deformation diagram shall then be used to determine the change in the maximum deformation ∆δmax caused by a unit force Fd, then the maximum deformation δmax calculated from the following equation:
δmax = δ2 + ∆δmax"
A.2.5.2.2 Evaluation of effective tightened width (Method 1)
Insert the words "used in A.2.5.2.1" after "test piece" in the first sentence:
The test piece used in A.2.5.2.1 shall be placed in the apparatus at an ambient temperature of 20 °C ± 3 °C, compressed to a deformation equal to δmin and the relevant tightening force F and effective tightened width bt measured and recorded.
A.2.6.2 Mean pressure (Method 1)
Correct de definition of f:
"f is the mean pressure, in megapascals (newtons per square millimetre);"
A.3.3.1 Method 1 Correct in the title of Figure A.2 the reference to table A.3:
Figure A.2 — Basic assumptions for the example in Table A.3
Annex C: C.4.1 General
Replace figures C.2a and C.2b by the following:
EN 1916:2002/AC:2006 (E/F/D) 4
Figure C.2 a) Figure C.2 b)
(not for pipes DN ≤ 1 200) Figure C.2 c)
Figure C.2 — Typical arrangements for the crushing test on circular pipes
Annex E: E.4 Procedure (hydrostatic test - routine and initial type tests)
Add reference to Method 4 in first sentence:
"Where the durability of joints is demonstrated by either Method 1, Method 3 or Method 4 in 4.3.4.2, a single unit shall be clamped securely in the apparatus, its ends closed and then filled with water, taking care to ensure that all the air is removed. The internal hydrostatic pressure shall then be raised gradually to 50 kPa (0,5 bar or approximately 5 metre water column), measured from the centre-line of the unit, and maintained for a period of 15 minutes, during which time the unit shall be evaluated for conformity to 4.3.7, before reducing the internal pressure to zero."
Annex E: E.5.2 Watertightness during angular deflection
Clarify the procedure for preventing the joint gap from closing by deleting the word "mean" in the 3rd sentence:
"The units shall be deflected to an angular deflection of 12 500/DN (or 12 500/WN, as appropriate to the shape of the bore) 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 egg-shaped units the deflection shall be in the vertical plane. During this operation the joint gap shall be prevented from closing at any point by, for example, interposing at the appropriate place a packing with a thickness equal to the [ ] value of the clearance stated in the factory documents.
Annex E: E.5.3: 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
EN 1916:2002/AC:2006 (E/F/D) 5 where
Ww is the weight of one unit filled with water, in kilonewtons
Where the full length of the pipe bore is not filled with water the formula shall be adjusted accordingly."
Annex F: F.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 H: Table H.1 :
Correct sampling procedures for concrete cover according to clauses 5.2.2 and 5.3.3: - 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 by the word "collapse" for the routine inspection.
Table H.1 — Sampling procedures Clause Test when specified Initial type test Routine inspection 5.2.2 and 5.3.3 Concrete cover 1 S using every pipe that has been type-tested to 5.2.3, or using covermeter for other units every pipe that has been tested to collapse and, using covermeter, 2 N/day
EN 1916:2002/AC:2006 (E/F/D) 6 Annex H: Table H.2 :
Clarify sampling procedure for initial type test of joint assembly by adding " or, at the manufacturer's discretion, one such pair of units with the most unfavourable tolerances."
Clarify sampling procedure for joint assembly tests under routine inspection by adding "joint assembly of a" before ". pair of units.":
Table H.2 — Sampling procedures for joint assembly tests Tests
1) Angular deflection and
2) shear load,
or
3) angular deflection and shear load combined. Initial type test Routine inspection (where Method 1, 3 or 4 has been used in 4.3.4.2 to demonstrate the durability of joints) Two pairs of units from the same group: - having the same seal profile section; - having the same joint profile that is effective when jointing, or, at the manufacturer's discretion, one such pair of units with the most unfavourable tolerances. One joint assembly of a pair of units from the same group per 1 000 produced but not less than one test per year: - having the same seal profile section; - having the same joint profile that is effective when jointing; or, at the manufacturer's discretion, if the initial type test has been successfully carried out with the most unfavourable tolerances, it is permissible to verify only joint and joint seal profile dimensions at a frequency as stated in the factory documents, but not less than: - one unit per 25 produced for each nominal size and type; - one unit per day for each nominal size and type.
