Device licensing
How do I know if I need a license and what type of license I need?
Any weighing or measuring device being used commercially (that is if a price is based upon the reading of the device) in the State of Oregon requires an annual license through the Department of Agriculture.
 

What do I do if I want to use a scale commercially?
First, you need to contact our office to request a license application for your equipment. Second, you need to complete the license packet (which includes the application and a placed in service report for the equipment) and submit your payment with these forms. After you complete these two steps you can begin using your weighing/measuring equipment. An inspector will stop by when in your area to inspect and approve the equipment.


Can I submit my license application online?
No, we do not have the license applications available in an online form. If you contact our office by phone at 503/986-4670 or by email at msd-info@oda.state.or.us to have an application mailed or faxed to you right away. The information we need in order to send you an application is as follows:
  • Business mailing address
  • Location address of the weighing or measuring equipment
  • Phone and fax numbers
  • The manufacturers rated capacity of the device
  • How you would like us to deliver the forms to you

Can I call in my credit card number for license payment?
No, we cannot accept a Visa or MasterCard payment without the cardholder's signature.  You may fax your application to 503/986-4746 along with a copy of the credit card number, expiration date and signature on the back of the application.

If there is a change in ownership at a business, do I need a new license?
The Measurement Standards Division licenses the weighing/measuring devices, not the operator. If ownership changes at a business with devices currently licensed by the division, no new license is required. Please notify our office so that we may update our records.

If I am replacing currently licensed equipment, do I need a new license?
No. If you have, for example, two scales, both licensed. One breaks down and you replace it, you do not need to license the new scale. You would still have two valid licenses because you are using two scales. However, you will need to file a new placed in service report for the new or replacement equipment.
 

When do I need to license my weighing or measuring device?
You must license a weighing or measuring device if you will be using it commercially. If you base a price for goods or services upon the reading on that device (such as by the pound, or gallon), you need to have a license for the device.
 

If I am selling produce at a Farmer's Market, do I need to have a licensed scale?
Not necessarily. There are some regulations regarding the method of sale for produce that can bypass the need for a scale. If you will be selling by weight, you need a licensed and approved scale. See our Farm market page for more specific informaiton.



What should I do if I am adding more weighing or measuring devices to my business?
First, you need to contact our office to request a license application for your additional equipment. Second, you need to complete the license packet (which includes the application and a placed in service report for the equipment) and submit your payment with these forms. After you complete these two steps you can begin using your weighing/measuring equipment. An inspector will stop by when in your area to inspect and approve the equipment.

Firewood
What is a cord?
Firewood is sold by a measurement called a "cord". A cord must equal 128 cubic feet. To be sure you have a cord, stack the wood neatly by placing the wood in a line or a row, with individual pieces touching and parallel to each other, making sure that the wood is compact and has as few gaps as possible. Then measure the stack. If the width times the height times the length equals 128 cubic feet, you have a cord of firewood. See Method of sale for fireplace and stove wood  for more.

What do I do if I have a complaint regarding firewood?
For quantity issues:
Contact Measurement Standards Division. We will send out an inspector to measure the firewood. The firewood should be stacked in a compact manner. No wood can be used until one of our inspectors measures the firewood.
phone: 503/986-4670
For quality issues:
Contact the Justice Department
Hot Line: 503-378-4320

Metrology laboratory
What type of calibration services are available at the metrology lab?
  1. Mass
  2. Length
  3. Volume
See more on the Calibration services web page.

Is the metrology laboratory in Oregon nationally accredited?
In order to meet their audit requirements, many laboratory customers regularly require information on the traceability of Oregon´s measurements. Oregon´s traceability is recognized by the National Institute of Standards and Technology, Weights and Measures Division (NIST-WMD) and is accredited by the National Institute of Standards and Technology, National Laboratory Voluntary Accreditation Program (NIST-NVLAP). The measurement parameters can be found on the NIST-WMD recognition certificate and on the NIST-NVLAP website .

Motor fuel quality
What standards does Oregon have for gasoline and diesel fuels?
Oregon adopts motor fuel standards developed by the American Society for Testing and Materials (ASTM). These are nationally recognized standards and are used by regulatory agencies and industry alike.

What is gasoline octane?
Octane is a measure of a gasoline´s antiknock performance, in other words, its ability to resist "knocking" which is a metallic rattling or pinging sound that results from uncontrolled combustion in the engine´s cylinders.

Nat'l type evaluation program
What is NTEP?
NTEP stands for the National Type Evaluation Program. The National Conference on Weights and Measures, in conjunction with industry and weights and measures officials, established a Task Force to develop NTEP in 1976. The purpose of NTEP was to establish a uniform set of criteria and test procedures for the evaluation of commercial weighing and measuring devices.

When was NTEP established?
NTEP was established in 1984 and is a cooperative program among manufacturers, users, and weights and measures officials. Prior to the adoption of NTEP there were 16 different type approval agencies in the United States. With the establishment of NTEP, a single evaluation can satisfy all states. In addition to promoting uniformity it reduces:
  • cost and time in getting a device to market,
  • the burden on state type approval programs,
  • costly mistakes to device users,
  • enables tests not practical in the field to be conducted prior to the device being sold for commercial use.

An NTEP evaluation is the one time that device is subjected to testing that includes maximum capacities and all features specified by the manufacturer. At the present time, 46 of the 50 states are NTEP states. That means they require an NTEP Certificate of Conformance (CC) for any device used commercially in their state.

Since Oregon is an NTEP State, how does that affect you?
First of all, it means that the manufacturer of a device must submit it for an NTEP evaluation prior to its being sold for commercial use. The user and scale company must purchase and sell only devices with an NTEP CC if the device is to be used commercially (unless it meets the exceptions of OAR 603-027-0640(2)(f)). The weights and measures officials must verify that the specific model of the device is covered by the NTEP CC and is set up consistent with the CC.

Where do you find out if a device has a NTEP CC?
Prior to January 1998, hard copies of CC were published in NCWM Publication 5. Now all CC´s are available online through the NCWM web site. Also, the manufacturer of a device should be able to provide you with NTEP information concerning their device.

Why do I need to know if a device is NTEP approved?
All devices put into commercial use in the State of Oregon after August 1990 must have a CC, or meet the exception as noted above. Once you verify the NTEP CC number of the device you will need to include that information on your placed in service report. After you have completely filled out the placed in service report and sent it in with your license application, you will be able to use your device commercially.

Placed in service reports
What is placed in service?
"Placed in service" means to install or repair following official rejection of any weighing or measuring device used commercially or intended to be used commercially.

What is a placed in service report?
The placed in service report is available from the Measurement Standards Division. It must be completed and returned to the Division when new and/or used devices are newly installed or restored to service after official rejection by the Measurement Standards Division. Properly completed rejection tag(s) shall suffice in lieu of a placed in service report for device(s) restored to service following official rejection.

Where do I get a placed in service report?
Contact the Oregon Department of Agriculture, Measurement Standards Division, 635 Capitol Street NE, Salem, Oregon 97301-2532, or you may call the Division at (503) 986-4670. You may download the following placed in service reports (in PDF form) here:

Transaction verification
What is it?
Transaction verification is a program of the Measurement Standards Division used to prevent consumer fraud and ensure fair competition by verifying that scales are properly functioning and scale users are correctly operating their scales. This program is carried out in a number of different ways. This includes but is not limited to, test purchases of bulk food commodities, audit testing, net contents testing, etc.

What does it accomplish?
  • It verifies that scales are in proper working order and are properly functioning.
  • It verifies that scale users are correctly operating their scales.
  • It ensures proper usage of scales when an inspector is not present.
  • It verifies the application of correct tare weights.
  • It protects consumers.
  • It maintains a level playing field.

What does it include?
  • Test purchases
  • Method of sale
  • Audit testing
  • Package testing
  • Package labeling

What if I have more questions about the transaction verification program?
Please also see the NIST publications Handbook 130 and Handbook 133.

Weighing and measuring devices
How do I find a device or repair person?
You can look up scales/meters in your local phone book for companies in your area. You may find a service company in your area by searching the online database (The state does not endorse or sponsor products, services or information provided by this link.). Make sure that you purchase a legal for trade scale. You can contact our office for a list of service companies within Oregon, although we do not make recommendations.
 

What do I do if I feel that I have been shorted at a gas station?
We commonly receive complaints from consumers because they believe that a gas station wrongfully charged them for more fuel than they actually received. While this may be the case, there is often a misunderstanding of the amount of fuel that can be dispensed into their vehicle, or a fuel can. Please visit our Understanding fuel tank capacity page for more information regarding possible reasons for variations in fuel tank capacity. You may contact the Measurement Standards Division to speak to someone and have a complaint form mailed to you, or you may submit a motor fuel complaint form online.

My device was tagged by a state inspector, what do I do now?
A blue tag means that your device is not operating within the state specifications. You must make the repairs, or hire a repair person to make the repairs. The person making the repairs should complete the back side of the tag and send it back to our office. Once our office receives the tag, it will be forwarded to the inspector for verification.
 

What can I do if my fuel dispenser cannot compute prices over $4.00 per gallon?
There are some options for using fuel dispensers that cannot compute over $3.99 9/10 per gallon. For details on the requirements and other important information, please see our motor fuel unit price computing page.

Wholesale terminal meters
What is the requirement for temperature determination at wholesale terminal meters?
Refined petroleum wholesale loading terminal meters are required to have a means to determine the temperature of the liquid product, commonly known as a thermometer well, either:
  • in the liquid chamber of the meter, or
  • immediately adjacent to the meter in the meter inlet or discharge line.

If I have a temperature probe at the meter, is a thermometer well still required?
Yes. The thermometer well is used when testing the meter as a means to verify the temperature recorded from the probe.

How long do I have to come into compliance with this requirement?
To help accommodate businesses to comply with this requirement, the Measurement Standards Division will allow until July 1, 2006 to upgrade refined petroleum wholesale terminal meters.

What will happen if my wholesale terminal meter is not upgraded by the deadline?
If a wholesale meter system does not comply with this requirement following July 1, 2006, it will not be tested and will be rejected.

What if I have more questions about this requirement?
