“issue(s)” to “item(s)”; Updated Form 15; and Updated 

content to reflect current practices. 

1-8 

S.1.7.(a) 

Replaced "total platform" with "gross" for consistency in 

wording with corresponding requirements in other device 

codes and for clarity. 

2-6 

S.2.1.3. 

Replaced the term “automatic zero-setting mechanism” with 

the term “automatic zero-tracking mechanism” to eliminate 

the potential that the term “automatic zero-setting 

mechanism” could be confused with the OIML R76 term 

and definition of “automatic zero-setting device.” 

2-10 

S.2.1.3.1., 

S.2.1.3.2, and 

S.2.1.3.3. 

Deleted the term “zero-tracking” and replaced it with 

“automatic zero-tracking mechanism” for consistency 

among all Section 2.20 code requirements for this feature. 

2-10 

N.1.3.2. 

(previously 

N.1.3.3.) 

Added language for the shift test load and test pattern that 

was eliminated with the deletion in 2007 of Scales Code 

paragraph N.1.3.1. 

2-19 

N.1.5. 

Replaced the reference to "automatic zero-setting 

mechanism (AZSM)" with the term "automatic zerotracking mechanism (AZT)" for consistency among Section 

2.20 code requirements for this feature. 

2-22 

Table T.1.1. 

Added reference in the column titled “Other Applicable 

Requirements” to paragraphs T.N.8.1.4. (Operating 

Temperature) and T.N.9. (Radio Frequency Interference 

(RFI) and Other Electromagnetic Interference 

Susceptibility). 

Added footnote4 which clarifies that paragraph T.N.8.1.4. 

Operating Temperature is nonretroactive and effective for 

unmarked devices manufactured after January 1, 1981. 

2-27 

T.4. 

Deleted paragraph T.4. and placed a reference to paragraph 

T.N.9. Radio Frequency Interference (RFI) and Other 

Electromagnetic Interference Susceptibility in Table T.1.1. 

Tolerances for Unmarked Scales in the column titled “Other 

Applicable Requirements.” 

2-28 

T.5. 

Deleted paragraph T.5. and placed a reference to paragraph 

T.N.8.1.4. Operating Temperature in Table T.1.1. 

Tolerances for Unmarked Scales in the column titled “Other 

Applicable Requirements.” 

2-28 

UR.1.3.1. 

Deleted reference to a "nonretroactive January 1, 1986" 

enforcement date, which does not apply to devices excluded 

from the requirement. 

2-37 

2.20 Scales 

Scale Code 

Index 

Replaced the term "automatic-zero setting mechanism" with 

the term "automatic zero-tracking mechanism" for 

consistency among Section 2.20 code requirements for this 

feature.
