Radar/Lidar Testing Program: How It Works

Radar/Lidar testing is being conducted at the two IACP laboratories: Conforming Product List (CPL) testing, critical performance testing (CPT) and recertification testing. The very abbreviated descriptions of the testing procedures that follow do not include required pass rates and the steps that follow if these rates are not met.

CPL Testing

A manufacturer of a new type of radar/lidar unit who wishes the product to appear on the CPL must submit the unit to the IACP to be assigned to the appropriate laboratory for testing against the requirements of the Model Minimum Performance Specifications for Police Traffic Radar/Lidar Devices. If the model passes, it is entered on the CPL. The first 200 units of that type to be produced must then be submitted for CPT. The critical performance test — a less stringent version of the CPL test — has been determined to be sufficient to assure the accuracy and performance of each new unit. These tests are performed at the manufacturer's expense prior to delivery to an agency for use in the field.

CPT

Each year , an IACP member will contact each radar/lidar manufacturer to obtain six units of each type appearing on the CPL, and ship them to a laboratory designated by staff. As an alternative, members who have purchased but not unpacked new units may be asked to assist in the program by sending the units to a laboratory for CPT at no charge. If an appropriate pass rate is not attained, 10 units of that model will be obtained and tested. If the pass rate is still not sufficient, the number of units tested escalates. If failures remain too high, a recall of all units or removal from the CPL could result. All of these tests are performed at the manufacturer's expense.

Recertification Testing

This program element provides law enforcement agencies with the opportunity to have in-service units tested for accuracy at any interval the agency considers appropriate. It has been suggested that radar/lidar units be recertified every two to three years or after the set has been "opened up" during repair. As mentioned above, this service can be accessed by contacting IACP. The charge to the agency for this service is minimal.
