Central Metering Unit The following notes will be taken to consideration:

1. Static Watt-hour Meters - Active energy poly-phase static meter for direct connection.

See items of Specification.

2. Maintenance

Maintenance is any action taken to:

• Replace a faulty meter with a properly working one, after a failure, and

• Test the operable condition of a replaced meter.

Note. Both these actions should conform meter replacement time (MRT).

A2. RAM Requirements

The Bidder is required to provide I.E.Co with meters with the following RAM properties:

1. Reliability

• MTTF (operating time to first failure): 20 years or more.

• 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.

A6. Reliability Demonstration

I.E.Co has the privilege to exercise a Reliability Field Demonstration (RFD) concerning the supplied meter. The purpose of the RFD is to verify that the meters meet the reliability requirement, i.e., MTTF of 20 years.

If subject to execution, the RFD will be conducted in accordance with the following principles:

1. The RFD shall be objective, quantitative and based on data collection from returned faulty meters (see IEC60300-3-2 Application Guide, IEC62059-21).

2. The Contractor has nothing to do in the RFD, except to participate in the Failure Review Board (FRB). However, the Contractor has to do his best in his plant in the following areas, in order to supply to I.E.Co with reliable meters, and thus to pass the RFD with high probability:

• Design and Development.

• Parts, materials, and components.

• Manufacturing Processes.

• Quality Management and Control.

• Tests and inspections.

• Subcontractors, Suppliers, and Vendors supervision.

• Packaging, Handling, Storage, and Transportation (PHST).

3. The FRB is the only body entitled to classify failures as “Relevant”, or “Non-relevant” for the purpose of the RFD.

4. The Contractor is responsible for productive agency of RFD results.

5. The RFD shall be ended with either ACCEPT, or REJECT result.

6. The meaning of REJECT result is violation of the specification, and the contract will deal with such a situation.

7. The RFD will be framed in accordance with standard reliability test methods.

Note:. It is recommended to:

• Explore IEC60300-2, in order to show the dependability program of the offered meter.




• Explore IEC62059-11 and IEC62059-21, in order to demonstrate the dependability level by means of internationally agreed procedures for dependability data collection.

However, if it will be agreed between I.E.Co and winner of the Contract, another equivalent test plan could be chosen and published, as required by the relevant national body of the country where the meter is manufactured.

8. The complete RFD plan, including demonstration parameters, will be prepared after contract award, in consultation between I.E.Co Reliability, and Equipment Dept. and the contract winner.

Central Metering Unit 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 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/e-mail. Rejection of 5 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 3 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. The same approach is to any field failure of rate ≥ 0.5% of total field installed meter. Along with the legal actions, in case of "serial failure" the winning Bidder is requested to provide:

• root cause analysis submission to I.E.Co within 30 days

• uninstallation of entire meter population of the problematic batches and replacement.

The winning Bidder is required to inform I.E.Co regarding similar to the provided to I.E.Co meters' failures at other customers.

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 meter deliveries with all the requirements of this specification at any stage of the contract.
