• Useful life: At least 16 years, without the need for maintenance or recalibration.
2. Maintainability
The RAM estimate based on free of “preventive maintenance” service. Corrective maintenance only
should applicable.
Note. Since I.E.Co approach to meter fault elimination is by means of valid replacement of a
damaged meter by another one (new or used, however tested as revised product) conducting by
appropriate billing, maintainability is converting to influence of definite meter type on mean time
of these replacement (MRT). The MRT shall not exceed 20 min for the same meter type replacement
by trained personnel.
A3. RAM Information
The Bidder shall submit to I.E.Co the following information regarding RAM:
1. RAM activities in his plant concerning the offered meter, and how he is organized to perform
these activities.
2. Supervising on his subcontractors, suppliers and vendors for their RAM activities.
3. The optimization shall consider the following:
• Criticality (long supply time, high price, short life length, high failure rate, single supply
source, sensitive or vulnerable materials, etc.
• Latent failure rate (λ), and induced failure rate (caused by human).
• Turn Around Time (door to door).
• Quantity in service.
• Recommended “probability of no shortage” (spares availability) on shelf.
• Cost.
A4. Bidder RAM Declaration
1. The Bidder shall state in Table A1 of the Annex AA attached to this document, the minimum

quantity of 5 meters for a Conformity of Compliance in 50 working days period after receiving the
order. The meters must be in their final version, manufactured or assembled in the same plant where
the remaining meters will be produced, tested with the same equipment that will be used in the
course of manufacturing, and packed in the same form that the future meters will be supplied. The 5
meters delivery must be accompanied by the data reading software, and the files described in
section 4.1.
After approval of these 5 meters the awarded bidder must send to the I.E.Co the meters as
preliminary (preproduction) series again, this time by quantity of one full pallet.
100% inspection will be applied to this pallet.
If the meters and the packing of the preliminary series are found to be in full compliance with
I.E.Co requirements with Acceptance Quality Limit (AQL) equals 1 or better (IEC62058-11) - they
will be approved by I.E.Co.
After the Israel Electric Co. approves Conformity of Compliance, the company will select 4 meters
from the preliminary series of production as representing a reference sample. One meter will be
returned to the manufacturer and the other three will be kept in the company until the end of
contract.
10.6.2 Series Production and Acceptance Test
The meters shall be manufactured and calibrated in homogeneous production series and supplied in
piles. The piles on appropriate pallets will be grouped for shipping in standard containers, trucks,
or other simultaneously shipped aggregate platforms. An inspection shall follow the “serial quality”
approach regarding units of such containers or trucks.
The meters must be manufactured under ISO 9001(2008) over a whole contract period. Valid ISO
9001(2008) approval certificate issued by a Certification Body (CB) which is a qualified by an
Accreditation Body (AB) must be available at any stage of the contract.
The content of the shipped meters' main total register (OBIS 15.8.0) shall not exceed 10kWh.
Acceptance lot-by-lot inspection by attributes will be performed at the Meter Test Station according
to IEC62058-11, ISO2859-1 and IEC62058-31. Lot for the acceptance inspection will be defined as
cumulative quantity of piles that have been delivered to I.E.Co Metering Unit premises within one
container or truck. Alternatively, I.E.Co may define a lot at its sole discretion.
Inspection level II will be used. Single sampling plan for normal inspection, AQL=1 will be
used regarding non-critical nonconformities (as per table 4 in IEC62058-31).
For critical nonconformities (as per table 4 in IEC62058-31) Single sampling plan for normal
inspection with acceptance number 0 will be used.
If lot will be rejected next lots will be tested according to Double sampling plan for normal
inspection.
Other meter's attributes may be tested for conformity. Failures in these tests will be
Page 26 of 52 SPECIFICATION

considered as non-critical nonconformities
Regarding nonconforming meters applicable procedures are given by IEC62058-11 and shall be
continued by the following measures. In case of rejection the whole lot will be replaced by
reshipping, or arresting on the place with 100% revision before presenting for re-inspection. The
Contractor will be responsible for bearing all associated costs. The Contractor will be notified by
phone/facsimile/e-mail. Rejection of five or more lots upon the same order delivery will be
considered as Contractor’s failure, and will lead to legal action.
The results of the acceptance tests will be reported to the I.E.Co Import Department that will notify
the manufacturer about the acceptance tests failure.
The nonconforming meters within a lot in quantities, which are still within acceptance criteria, will
be subject to replacement if claimed by the Purchaser.
Note: In order to prevent any holdback in I.E.Co to install newly purchased meters due to rejected
lots, the Manufacturer will be obligated to expedite extra deliveries, above and beyond the agreed
timetable.
If three or more meters delivered according to the same order will be found with a same
failure caused by production failure, or wrong meter construction, or component
failure, which affects normal operation of the meter, the failure will be considered as "serial
failure" and will lead to legal action.
During the life cycle of the meters I.E.Co may conduct from time to time and at its sole discretion
number of tests detailed in the Type Test procedure, in order to ascertain the stability of the meter
metrology characteristics. If the meters fail to comply with the test requirements, the manufacturer
will assume responsibility.
I.E.Co representative, at I.E.Co sole discretion, may visit and inspect the active production line
being used to manufacture and assemble the meters in order to assure the suitability and
compatibility of the new (or renewed) meter deliveries with all requirements of this specification at
any stage of the contract.
