2.1. Vendor Instructions

For each proposed material, Vendor shall complete the attached Exhibit A - Material Qualification and submit via email to

AMI_Materials_RFQu@wsscwater.com. WSSC Water will review and confirm form completeness, and for meters, confirm eligibility against attached Meter Specifications. Only upon confirmation from WSSC Water, the vendor may deliver the associated physical material sample(s) to WSSC Water's Meter Shop. Meter deliveries must follow the delivery requirements listed in Exhibit A.

Completing Exhibit A - Material Qualification Worksheet:

Complete and submit worksheets based on your type of product delivery. Fill the fields highlighted in yellow for each material model submitted. Manufacturer name and model names must be present on the material submittal sheet. Distributors are not permitted to submit products to this Request for Qualification.

Worksheet-specific instructions are below:

• Enter model name/ number in row 4, under the matching meter type and size for that model

• Provide responses to all qualification items

1. Return slip (yes/no) - identify whether a paid return slip has been included for this sample to returned to the

Vendor after evaluation. A pre-paid return slip is required for any samples a Vendor wants returned. Note that any returned samples will be in used condition.

2. AMI/AMR Read mode - identify whether the meter is compatible with AMI solution, AMR solution, or both via programmability

3. Register resolution - provide meter read resolution units, number of digits shown for visual read, precision of visual and transmittable reads

4. Expected battery life for digital meters - time to register battery failure if connecting with an AMI transmitter for 15-minute, hourly, and daily read transmissions

5. Climate requirements - provide requirements for installation environment, including temperature exposure limits

6. Weatherproofing - provide details of proposed material's waterproofing ratings, corrosion resistance, ultraviolet degradation resistance, and other protections against the wear of outdoor environments

2 - Required Meter Accessories
