Hybrid III 10-Year-Old Child Test Dummy; Corrections;
Incorporation by Reference
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation (DOT).
ACTION: Technical amendments.
-----------------------------------------------------------------------
SUMMARY: NHTSA published a document in the Federal Register on February
27, 2012 (77 FR 11651), establishing specifications and qualification
requirements for a Hybrid III 10-year-old child size test dummy. The
regulatory text adopted by that document contained errors, as did some
of the drawings of the test dummy and other materials incorporated by
reference pertaining to the test dummy. This document corrects those
errors by revising regulatory text and incorporating by reference a
corrected drawing package. We have also made conforming changes to the
parts list and users' manual for the dummy, which this document also
incorporates by reference.
DATES: Effective date: June 23, 2015. The incorporation by reference of
the publications listed in this document has been approved by the
Director of the Federal Register as of June 23, 2015.

SUPPLEMENTARY INFORMATION:
This document corrects 49 CFR part 572, ``Anthropomorphic Test
Devices,''
[[Page 35859]]
Subpart T, ``Hybrid III 10-Year-Old Child Test Dummy (HIII-10C).''
NHTSA published a final rule on February 27, 2012 (77 FR 11651),
establishing Subpart T, which contains specifications and qualification
requirements for the HIII-10C. The regulatory text adopted by that
document contains errors, as do some of the drawings and other
materials incorporated by reference pertaining to the test dummy. This
document corrects those errors by revising regulatory text and
incorporating by reference a corrected drawing package, parts list and
users' manual.
Need for Correction
Corrected Regulatory Text
The following corrections are made to the regulatory text.
a. Sections 572.170 and 572.171 of subpart T incorporate by
reference a drawings and inspection package, a parts/drawing list, and
a users' manual (``Procedures for Assembly, Disassembly and
Inspection'' (``PADI'')) for the HIII-10C by name and by date. NHTSA is
correcting several drawings in the package, and is making conforming
changes to the parts list and to several figures in the PADI. For ease
of use, rather than switch out individual drawings from the previous
drawings package and individual pages from the original PADI and risk
confusion by users in the future about which drawings and pages were
replaced, NHTSA is incorporating by reference a new set of materials.
We are referencing a new drawings and inspection package that has the
corrected drawings, a new parts/drawing list, and a new PADI. All these
new materials are dated March 2015. We are amending Sec. 572.170 and
Sec. 572.171 to reference the new versions of the materials.
b. The February 2012 final rule incorrectly specifies in 49 CFR
572.177(a)(1) that the thorax impact probe mass is 6.89
0.012 kilograms (kg) (15.2 0.05 pounds (lb)). Figure T4 of
subpart T correctly lists the thorax impact probe mass as ``6.89 0.05 kg (15.2 0.1 lb).'' We are correcting the
second sentence of 49 CFR 572.177(a)(1) so that it refers to ``6.89
0.05 kg (15.2 0.1 lb).''
Likewise, the February 2012 final rule incorrectly specifies in
Sec. 572.177(a)(2) that the knee impact probe mass is 1.91 0.01 kg (4.21 0.02 lb). Figure T6 of subpart T
correctly lists the knee impact probe mass as ``1.91 0.05
kg (4.2 0.1 lb).'' We are correcting the second sentence
of 49 CFR 572.177(a)(2) to reference a mass of 1.91 0.05
kg (4.21 0.1 lb).
c. The February 2012 final rule inadvertently excluded a
specification for the filter class used for the knee probe acceleration
and for the thorax probe acceleration. The filter class used for the
knee probe acceleration is SAE International (SAE) Channel Frequency
Class (CFC) 600. CFC 600 has historically been applied to other dummy
knee probe accelerations and NHTSA used CFC 600 in developmental
testing of the HIII-10C. The filter class used for the thorax probe
acceleration is CFC 180. NHTSA specifies the CFC 180 filter class with
other test dummies and used it in developing the HIII-10C. Accordingly,
NHTSA corrects 49 CFR 572.177(c) by adding the filter classes for the
knee and thorax probe accelerations.
Corrected Drawings
Drawing 420-5120, Upper Leg Flesh
In the revisions table for this drawing, in Rev F, the overall
Upper Leg Flesh height dimension is correctly specified as ``4.50 +.06/
-.18 (was 4.5 +.16/-.13).'' Elsewhere on the drawing, the height
dimension next to the part does not match this value in the table. We
have corrected the height dimension next to the part to match that of
the table.
In Drawing 420-5120, the dimension for the overall Upper Leg Flesh
width is correctly listed, next to the part, as ``4.92 +.05/-.20.'' In
the revisions table, Rev F, the width dimension is different and
incorrect. We have corrected the revisions table to match the dimension
listed next to the part.
Drawing 420-4300, Abdomen
In the revision history table, Rev F, the width of the abdomen
pocket is correctly stated as (3.77) and the depth is correctly stated
as (2.14). Elsewhere on the drawing, the dimensions listed for those
parts do not match those correct dimensions in the revision history
table. We have corrected the drawing to match the correct dimensions in
the table.
In the revision history table, Rev E, Note #2 had read: ``All
Dimensional Tolerances Are 0.12 inch.'' The note was
incorrectly removed, and in Rev F, a 0.06 inch tolerance
was incorrectly added to two dimensions (0.75 0.06 and 0.62
0.06). The 0.06 inch tolerance is in error; it
is an unrealistic dimensional requirement for a molded part. We have
revised the drawing to reestablished the 0.12 inch
tolerance for this part.
Drawing 420-1001, Skull, Machining, 6-Axis
The drawing package incorporated by the February 2012 final rule
had drawing 880105-102, which had an error with respect to the
dimensions called out for the center of gravity (CG) location of the
skull. The correct CG dimensions for the head assembly are in drawing
420-0000, Sheet 4 of 5, as follows: CGx = 2.330 0.100 inch
and CGz = 1.200 0.100 inch. We have removed drawing
880105-102 and have revised drawing 420-1001 (Rev D) to add information
on the CG location.
Revisions Relating to Shoulder Assembly Drawings
Some of the drawings of the HIII-10C's shoulder area are incorrect
because they depict the design of the dummy at the time of our
publication of the notice of proposed rulemaking (NPRM) \1\ preceding
the February 2012 final rule, and not the design of the HIII-10C as it
was adopted by the final rule. As adopted by the final rule, the HIII-
10C has a shoulder assembly design that can be modified by switching a
part of the shoulder assembly (the shoulder yoke), to enable the dummy
shoulder to accommodate either a load cell or a structural replacement
(SR) in place of a load cell. The drawings adopted by the final rule
show the shoulder yoke that accommodates an SR, but we inadvertently
did not include drawings showing the HIII-10C with the shoulder yoke
assembly that accommodates a load cell. We have corrected this
oversight by including in the new drawing package drawings of the
alternate shoulder yoke assembly that accommodates a load cell, and
drawings of the load cell and assorted hardware.

\1\ 70 FR 40281, July 13, 2005, Docket No. NHTSA-2004-21247.
---------------------------------------------------------------------------
Corrected PADI
We have revised various figures in the PADI to conform the manual
to the changes discussed above. Most of the revisions relate to using
the shoulder yoke assembly when using the HIII-10C with a shoulder load
cell. The revised figures are: 12, 21, 22, 24, 29, 82 and 83.
