For the BPVC edition, the Summary of Changes page, followed by the List of Changes in Record Number Order, are set as the last section of the front matter.
In the edition, pages within the Summary of Changes and List of Changes in Record Number Order receive a lowercase roman numeral folio.
Three paragraphs precede the summary of changes entries. The statement includes
an explanation of the revisions included in the edition, followed by statements about the mandatory date
an explanation of the record number listed in the Change column
an explanation of the use of margin designators
If the edition contains no revisions, the following statement replaces the second paragraph, and the third paragraph is omitted:
No revisions are contained in Section XX of this Edition.
The summary entries are presented in three columns: Page, Location, and Change (Record Number).
The Page column lists the affected pages in consecutive order, including point pages for addenda (it is especially important to inform the user of point pages since this is new material and will affect the replacing of pages). Following are some general guidelines for preparing the page column:
Isolate individual changes to a page as often as possible (instead of running material over to another page that also contains changes), thereby listing one page at a time.
If more than one change occurs on a page, list all changes under that one page number.
EXAMPLE:
|
36 |
26-8.6.1 |
Editorially revised (00-000) |
|
|
L-7.6(a) |
Subparagraphs (1)(b) and (6) revised (00-000) |
If a single change affects two consecutive pages (either revises material on both pages, or flows off the first page, necessitating creation of a “point page”) those page numbers should be listed together, separated by a comma.
EXAMPLES:
|
26, 26.1 |
RT-320 |
Editorially revised (00-000) |
|
31, 32 |
3-600 |
Revised in its entirety (00-000) |
If three or more consecutive pages are affected by a single change that affects all of those pages, the first and last pages affected should be listed, with an en dash.
EXAMPLES:
12–14.1
89–92
108.1–108.5
If it affects three or more pages, with unaffected pages in between (for example, full-page figures or tables), list all affected pages separated by commas.
EXAMPLE:
|
21, 22, 24, 25 |
NF-3320 |
Revised in its entirety (00-000) |
The location listed in the Location column indicates as closely as possible the current designation of the unit(s) of material undergoing revision. The location listing should be carried out to the furthest possible designator or breakdown, without causing unnecessary repetition in the Change column. For example, if paras. 20-1.6.2(a)(1) through 20-1.6.2(a)(5) were changing, it would be best to list 20-1.6.2(a) in the Location column and explain the changes to the numbered subparagraphs in the Change column.
As stated earlier, the location column correlates directly to the margin note in its placement and quantity, as indicated in the following examples:
EXAMPLES:
|
7 |
NF-3321.1(a) |
Revised (00-000) |
[NF-3321.1 is a head, and (a) is a subparagraph of this head; the margin designator is aligned with (a), not the NF-3321.1 boldface head.] |
|
13 |
NF-3322 |
Revised (00-000) |
[NF-3322 is a head, and the margin designator is aligned with this head.] |
Sometimes, however, the change is more complicated, and therefore the one-to-one correlation does not apply, as shown in the following example. There should be no line spaces between the enumerated entries.
EXAMPLE:
|
16 |
PG-12 |
(1) Subparagraph (a) revised (00-000) (2) Subparagraph (a)(2) redesignated as subpara. (a)(3) and new subpara. (a)(2) added (00-000) (3) Subparagraph (g) deleted (00-000) |
[In this case, a margin note is aligned with the PG-12 boldface head.] |
Glossary items that are revised or added can be mentioned individually, as noted in the following example:
EXAMPLE:
|
18 |
crane |
Revised (00-000) |
|
20 |
overhead |
Added (00-000) |
For glossaries that contain several revisions, it is advised to group the changes under one location, as noted in the following example:
EXAMPLE
|
18 |
PG-3 |
(1) Definitions of material supplier and spiral weld revised (00-000) (2) Definition of porosity added (00-000) (3) Definition of primary stress deleted (00-000) |
|
Common Phrases. The Change column describes the change that has been made with a short phrase or explanation. The most common phrases used in the Change section are
(1) Revised
(2) ____________ revised
(3) Revised in its entirety1
(4) Deleted
(5) ____________ deleted
(6) Added
(7) ____________ added
(8) Redesignated as ____________
(9) ______________ added, corrected, deleted, or redesignated by errata2
The words "Figure" and "Paragraph" should be spelled out only when they begin an entry in the Location and Change columns.
The record number that follows is set in italics, in parentheses. Multiple changes listed for one Location should be organized in a numbered breakdown. There should be no line spaces between the numbered entries. A record number must be listed for each item in the numbered breakdown. If more than one record number applies to a single item, the numbers are separated by commas. See Sample.
Figures
When the physical appearance of a figure is altered, use the term “Revised.” If only one or two callouts are changed, specify the locations of the callouts in the Change column (e.g., “Callout at bottom-left of figure revised”).
Summaries for edition publications that include Interpretations have a note below the summary entries, with an 'h1' heading. See Sample.
___________________________________
1 Use this explanation when
more than half of the content under the noted heading has been revised
there has been a structural change (e.g., breakdowns have been added, deleted, or redesignated)
if previous paragraphs are renamed or new boldface heads are created from old breakdowns or old material
half or more of the table or figure has been revised
2 For errata corrections, it is especially important to refer very specifically to the place modified, as the errata item is correcting an error. For example, “Second and third lines of first paragraph corrected by errata,” or “Temperature value in third column from the left, third line down, corrected by errata.
