## ESTABLISHED TARE WEIGHTS

**ESTABLISHED TARE WEIGHTS**

***Common Tare Weights***
***Average Tare Weights***
***Predetermined Individual Tare Weights***
***Seasonal Tare Weights***
***Timber Tare Weights***

***The director shall adopt regulations for the establishment of vehicle, container, and pallet tares, including, but not limited to... ***

***the adoption of conditions of use***
***certificate requirements***
***sample size***
***allowable variations***
***and procedures to verify***

**A weighmaster shall:**
***identify on a weighmaster certificate, the use of an established tare weight, following requirements specific to the type of established tare used.***

## Use of Established Tares

**Common Tare****	****	****	****	****C.T.**
**Predetermined Tare(*except)****	****P.T.**
**Timber Tare****	****	****	****	****T.T.**
**	********rock, sand, gravel, asphalt***	****	**

**Identify on the weighmaster certificate**

## COMMON TARE WEIGHTS

**COMMON TARE WEIGHTS**

**ESTABLISHING:**
***1,000 lb or less***
***Uniform weight range ( 0.2 lb or 20 % variance between the highest and lowest )***
***Minimum of 96 containers or 100% of the lot***
***Round to nearest pound if greater than 30 lb; round to nearest 0.1 lb if 30 lb or less.***

## COMMON TARE WEIGHTS

**COMMON TARE WEIGHTS**

## Understanding Uniform Weight Range VS. Tolerance

**Understanding**** Uniform Weight Range VS. Tolerance**

_**Uniform weight range**_** is the maximum allowable variation of weight from the average (mean) that any individual container in the lot may weigh**

**For example:**
**Average weight for lot was 100 lb**
**20% variation equals 20 lb**
**Highest bin weight allowed would be 110 lb**
**Lowest bin weight allowed would be 90 lb**

## Understanding Uniform Weight Range VS. Tolerance

**Understanding**** Uniform Weight Range VS. Tolerance**

**For example:**
**Average weight for lot was 100 lb**
**20% variation equals 20 lb**
**Highest bin weight allowed would be 110 lb**
**Lowest bin weight allowed would be 90 lb**

## COMMON TARE WEIGHTS

**RESPONSIBILITY-**
***...”******it is the responsibility of the party for whom the tare weight was established to maintain the tare weight within the variations prescribed by the director.”***
**In no event shall tare weights exceed the tolerance level of 0.2 lb or 2 %, whichever is greater, of the established tare weight.**

**COMMON TARE WEIGHTS**

## Understanding Uniform Weight Range VS. Tolerance

**Understanding ****Uniform Weight Range VS. Tolerance**

_**Tolerance**_** for common tare weight is 2 % of the ESTABLISHED common tare weight**

**For example:**
**Common tare weight for lot is 75 lb**
**2% tolerance equals 1.5 lb**
**No violation until common tare average weight for sample ( 96 or 100%) weighed exceeds 76.5 lb or is less than 73.5 lb**

## Understanding Uniform Weight Range VS. Tolerance

**Understanding ****Uniform Weight Range VS. Tolerance**

_**Tolerance**_** for common tare weight is 2 % of the ESTABLISHED common tare weight**

## Understanding Uniform Weight Range VS. Tolerance

**Understanding ****Uniform Weight Range VS. Tolerance**

**For example:**
**Common tare weight for lot is 75 lb**
**2% tolerance equals 1.5 lb**
**No violation until common tare average weight for sample ( 96 or 100%) weighed exceeds 76.5 lb or is less than 73.5 lb**

## USE 

***Unless a party having legal or financial interest in the transaction notifies the weighmaster prior to issuance of a certificate that a Common Tare Notice (CTN) shall not be used,  a weighmaster may use a CTN if a copy of the CTN is on file.  ***

## Maintain a copy of the completed CTN at all weighing locations where it will be used.

## Average Tare

**Average Tare**

** ****Certificate issued will show the total number of containers, number of sample containers and the average weight**
** ****Determined for each load at the time of certification**
** ****Must meet uniform weight range conditions**
** ****Cannot be used for subsequent loads**

## Establishing

_**Establishing**_

**Average tare weight will be determined mathematically (total weight divided by sample number) and rounded to the nearest 0.1 lb if equal to or less than 30 lb or the nearest pound if greater than 30 lb.**
**Randomly select two (2) containers for the first fifty (50) in the lot and one (1) for each fifty (50) additional containers in the lot**
**No less than three ( **_**3**_** ) containers weighed  for a lot of **_**100**_** containers **_***OR LESS***_

## This procedure must be used for average tare if the containers are of such construction or treatment as to vary in weight as the result of hydrocooling. 

**This procedure must be used for average tare if the containers are of such construction or treatment as to vary in weight as the result of hydrocooling. **

## USE 

***Unless a party having legal or financial interest in the transaction notifies the weighmaster prior to issuance of a certificate that an average tare weight shall not be used,  a weighmaster may use it. ***
