5.3 Criteria for Acceptance Testing[1]

All new and reconditioned or repaired meters referred to the ERC for acceptance testing shall be sample tested by the ERC using ANSI Z1.4-1993, “Sampling Procedures and Tables for Inspection by Attributes”. An Acceptable Quality Level (AQL) of one percent (1%) must be achieved. Single sampling shall be performed in any of the three (3) inspections called normal, reduced, and tightened as shown in Tables 1, 2, and 3 below. Unless otherwise required by the ERC, normal inspection shall be used.

5.4 Switching Procedures[2]

The procedures for switching among normal, tightened, and reduced inspections are as follows:

5.4.1 Normal to Reduced Inspection

While Normal Inspection is in effect, Reduced Inspection shall be instituted if any of the following conditions has been met:

a)
After ten (10) consecutive field assignments of acceptance testing with less than five-day duration per assignment in a particular Meter Shop, an ERC authorized representative has not found any non-conforming meters in every sample tested lots; or
b)
After a field assignment of acceptance testing with five-day duration in a particular Meter Shop, an ERC authorized representative has not found any non-conforming meters in every sample tested lots.

5.4.2 Reduced to Normal Inspection

While Reduced Inspection is in effect, and it occurs that the number of non-conforming meters in a lot under inspection exceeds the criterion for acceptance, but less than the criterion for rejection, the lot under inspection shall be accepted, but the ERC authorized representative shall revert back to Normal Inspection in the succeeding lots.

5.4.3 Normal to Tightened Inspection

While Normal Inspection is in effect, Tightened Inspection shall be instituted if any of the following conditions has been met:

a)
After five (5) consecutive field assignments of acceptance testing with less than five-day duration per assignment in a particular Meter Shop, an ERC authorized representative has found two (2) failed lots in the sample-tested lots; or
b)
After a field assignment of acceptance testing with five-day duration in a particular Meter Shop, an ERC authorized representative has found two (2) failed lots in the sampletested lots.

5.4.4 Tightened to Normal Inspection

While Tightened Inspection is in effect, Normal Inspection shall be instituted if any of the following conditions has been met:

a)
After ten (10) consecutive field assignments of acceptance testing with less than five-day duration per assignment in a particular Meter Shop, an ERC authorized representative has found all the sample-tested lots acceptable; or
b)
After a field assignment of acceptance testing with five-day duration in a particular Meter Shop, an ERC authorized representative has found all sample-tested lots acceptable.

ARTICLE VI
IN-SERVICE TESTING

6.1 Statistical Sampling Program for In-service Meters[3]

A statistical sampling program shall be used to comply with the regulatory requirement of conducting periodic testing of all individual meters in service. Said tests shall be made once every two-year period after installation.

The statistical sampling program shall conform to the following criteria:

  1. The plan shall use ANSI Z1.4-1993, “Sampling Procedures and Tables for Inspection by Attributes” as the basis for random statistical quality control and random sample selection of meters as simplified in Table-4[4];
  2. Inspection level “General II – Normal”; and
  3. Acceptability Quality Level (AQL) of 2.5% must be achieved.

Notes:
  
* Meters In lots With sizes of 32 meters and below shall be tested individually

d)
The sample meter is no longer on site during the conduct of in-service testing.

(1) Indicates the number of meters in a lot
(2) Indicates the series number of sample testing
(3) Indicates the number of meters for sample testing
(4) Indicates the maximum number of non-conforming meters in sample to allow acceptance of the lot
(5) Indicates the number of non-conforming meters in sample to cause rejection of the lot
(6) Indicates the number of non-conforming meters in the first sample testing to necessitate a second sample testing
(7) Indicates the number of randomly selected meters as replacement to sample meters under any of the stipulated circumstances in Note **.

Section 2. All articles, sections, sub-sections, and tables not expressly revised herein shall remain in force and effect.
