ASTM E2300-09(2017) pdf free.Standard Specification for Highway Traffic Monitoring Devices.
ASTM E2300 describes the recommended procedure for identifying the performance and operating requirements to be included in a purchase order for Traffic Monitoring Devices. As such, the specification can be referenced by the user and seller when determining compliance with each specified requirement. It is the intent of this specification to have the user require the seller to provide evidence that the brand and model of TMD offered by the seller has passed an applicable Type-approval Test. If the TMD has not previously passed a Type-approval Test, then it is the intent of this specification to have the device type-approved before it is accepted by the user. If the TMD has previously passed a Type-approval Test, then this specification requires that the production version of the device provided by the seller pass an On-site Verification Test before being accepted by the user.
