wood in the stack and 

multiplying it by the number of

Width of Stack = Average Piece 

Length (APL) × Number of

3.14.3. Field Audit 

Procedure – Bundled and 

Bagged Firewood

After the bundle or bag is 

secured, use a flexible measuring 

tape to measure the 

circumference near each end of 

the bundle or bag of firewood as 

shown in (see Figure 3-13a. 

“Strapping the Ends of a 

Bundle”). Using one movement, 

extend the measuring tape around 

the end of the bundle or bag to 

obtain its circumference (see 

Figure 3-13b. “Measuring the 

Circumference of the Bundle”).

4.8.1.2. Audit Test 

Procedure

Note: Graph paper of an 

appropriate size that allows for 

tracing of the entire chamois shall 

be used. However, if a single 

sheet of appropriate-sized graph 

paper is not available, it may be 

necessary to tape sheets of graph 

paper together to create an area 

sufficient in size to measure the 

area for a chamois (e.g., chamois 

greater than 23.22 dm2 [2.5 ft2]).

4.8.2.2. Test Procedure

6. Calculate the area of the 

rectangle cut from the pattern by 

multiplying the length by width 

and record as Area (A) in square

centimeters or square inches.

• Several NIST publications, 

Federal Register Notices, and 

federal statutes and code of 

regulations references were 

updated in the footnotes. 

Website URLs were verified 

and updated.

• Unit symbols and 

abbreviations were added to 

the “starting units” column to 

improve usability.

• Removed the ångström unit to 

align with the latest edition of 

the BIPM SI Brochure and 

NIST SP 330, as it was 

eliminated in 2019.

• Added footnote guidance for 

users to consult federal/state 

laws and regulations and 

industry documentary 

standards to confirm the barrel 

quantity used for a specific 

application.
