APPENDIX 3
NEW EDI STATISTICS (DEFINITIONS)
NOTICE: The material in this appendix is an official part of SEMI T6 and was approved by full letter ballot procedures.
A3-1 Additions to ANSI’s Statistical Codes to be Included within this Standard
A3-1.1 These new statistical codes are added to a predefined ANSI list of summary statistics found in Appendix 3
under the transaction segment STA. The codes are HS, HW, HC, GM, GS, PK, EC, OC, and PE and are submitted
to ANSI for approval. The codes can be used in an EDI message as long as the trading partners agree to include
them as part of their transmissions. Once the codes are approved, the ASC X12 convention will be updated to
automatically accept these codes as standards.
A3-1.2 Histogram Information
A3-1.2.1 HS = Histogram Start (Left side of first class or bar)
A3-1.2.2 HW = Histogram Class Width (Width of class or bar)
A3-1.2.3 HC = Histogram Class Count (Count of classes or bars)
A3-1.3 Process Capability Information
A3-1.3.1 GM = Geometric Mean (GMEAN). For the lognormal distribution, it’s calculated as:
TMEAN = The mean of the natural log of the raw data values
GMEAN = EXP(TMEAN+ (TSIGMA**2)/2)
A3-1.3.2 GS = Geometric Sigma (GSIGMA). For the lognormal distribution, it’s calculated as:
TSIGMA = The sigma of the natural log of the raw data values
GSIGMA = SQRT((EXP((2*TMEAN)+(TSIGMA**2)))**EXP((TSIGMA**2))-1))
A3-1.3.3 PK = The peak of the fitted probability distribution function. It’s calculated as the maximum Y
value of the probability distribution function after it is fitted to the process histogram.
A3-1.3.4 EC = The equivalent normal Cpk (ECPK). For the lognormal distribution, it’s calculated as:
ECPK = ((LN(USL))-LN((GMEAN**2/(SQRT(GMEAN**2+GSIGMA**2))))/ (3*SQRT(LN
(GMEAN**2)/ GMEAN**2)))
A3-1.4 Outlier Information
A3-1.4.1 OC = Outlier Count. It may be calculated as A minus B, where A = the count beyond a chosen
sigma point using the histogram, and B = the count beyond the chosen sigma point using the statistical
distribution.
A3-1.5 Percentile Information
A3-1.5.1 PE = Percentile. Like the HG, it can be repeated to give different elements. The user and supplier
need to agree on the order for a particular application.

APPENDIX 4
EDI TRANSMISSION COMPONENTS (863 REPORT OF TEST
RESULTS)
NOTICE: The material in this appendix is an official part of SEMI T6 and was approved by full letter ballot procedures.
A4-1 Introduction
A4-1.1 The purpose of this section is to provide the
necessary information to enable trading partners to use
the ASC X12 standards for the exchange of electronic
business documents within the electronics industry.
A4-1.2 The transmission, in the ASC X12 format, is
comprised of an outer envelope (transmission envelope)
which identifies the sender and receiver. Within the
transmission envelope are one or more functional
groups.
A4-1.3 The functional groups are analogous to batches
of like documents (i.e., certificate of analysis, test
results, statistical results). Each functional group
contains one or more transaction sets (electronic
documents). Each transaction set is an ordered
collection of segments. Each segment is an ordered
collection of data elements.
A4-1.4 Each segment has been assigned a two or three
charac-ter identifier.
A4-1.5 This identifier marks the beginning of each
segment. Each element within the segment is separated
by a data element separator character. Electronic
Industry Data Exchange (EIDX) recommends the use of
the asterisk (*) character as a data element separator. A
segment terminator character is used to mark the end of
a segment.
A4-2 Format
A4-2.1 The ASC X12 segment hierarchy lists all
segments, in order, available from the ASC X12
standard. The segment ID’s that are shaded indicate the
segments utilized by EIDX. Following the ASC X12
segment hierarchy is a detailed description of each
segment in the order that they appear in the transaction
set.
A4-2.2 Each segment is listed with the segment ID and
name, level (header, detail, or summary), loop (if the
segment is contained within a loop), loop repeat (for the
first segment in the loop), requirement within the
transaction set, maximum use, purpose (as defined by
ASC X12), ASC X12 syntax notes, ASC X12
comments for segment usage, and notes that explain the
EDIX convention for this segment within the
transaction set. It is important to note all shaded text is
either an EDIX convention or EDIX terminology.
Shaded coded lists refer to recommendations culled
from the entire ASC X12 data element code list. The
unshaded areas contain definitions and comments from
the ASC X12 standard.
A4-2.3 The data element summary lists each data
element, in order, for the segment; for each data
element there is one line to identify reference
designator, data element number, data element name,
and attributes.
A4-2.4 Below the one line summary are usage notes
and ac-tual values identified for use.
A4-2.5 Reference Designator — This is the segment
identifier with the data element sequence number
within the segment.
A4-2.6 Data Element Number — This is the number
assigned to the data element by ASC X12. This number
may be used for direct refer-ence into the ASC X12
Data Dictionary.
A4-2.7 Data Element Name — This is the name
assigned to the data element by ASC X12, in the ASC
X12 Data Dictionary.
A4-2.8 Attributes — Each data element has three ANSI
attributes: element usage, element type, and
Minimum/Maximum length.
A4-2.9 Element Usage
M Mandatory Designer
This is the segment identifier with the data
element sequence number within the segment.
O Optional
The data element may be used if the segment
is used.
X Conditional
The data element may be used only if other
elements are used within the segment.
The particular condition/relation will be stated
in the Data Element Summary for the segment
when used.

A4-2.10 Element Type
ID Identifier
Values for the identifier-type data elements are
taken from a predefined list in the ASC X12
data element dictionary.
AN String
Values for the string-type data elements are a
sequence of any printable characters.
DT Date
Values for a date-type data element are in the
format YYMMDD.
TM Time
Values for a time-type data element are in the
format HHMM expressed in a 24-hour clock.
Nx Numeric
Values for a numeric data element are in an
implied decimal format, where "X" indicates
the number of places to the right of the
decimal point.
i.e.,
N0 is a whole number (999.)
N2 is 999.99
R Decimal
This is a numeric field in character format,
with a decimal point included. It is treated as
alpha/numeric. The decimal point is not sent
for whole numbers.
e.g.,
to send the number 0128.734, the field would
contain "128.734".
to send the number 0789.00, the field would
contain "789".
A4-2.11 Minimum/Maximum
This is the minimum and maximum length the field can
be.
e.g.,
02/02 - fixed length of 2 characters.
04/09 - Minimum length of 4 characters and maximum
length of 9 characters.
