`
`PURPOSE AND APPLICATION
`
`The Office of Vehicle Safety Compliance (OVSC) provides contractor
`laboratories with Laboratory Test Procedures as guidelines for obtaining
`compliance test data. The data are used to determine if a specific vehicle or item
`of motor vehicle equipment meets the minimum performance requirements of the
`subject Federal Motor Vehicle Safety Standard (FMVSS). The purpose of the
`OVSC Laboratory Test Procedures is to present a uniform testing and data
`recording format, and provide suggestions for the use of specific equipment and
`procedures. If any contractor views any part of an OVSC Laboratory Test
`Procedure to be in conflict with a Federal Motor Vehicle Safety Standard
`(FMVSS) or observes deficiencies in a Laboratory Test Procedure, the contractor
`is required to advise the Contracting Officer's Technical Representative (COTR)
`and resolve the discrepancy prior to the start of compliance testing.
`
`Every contractor is required to submit a detailed test procedure to the COTR
`before initiating the compliance test program. The procedure must include a
`step-by-step description of the methodology to be used. The contractor’s test
`procedure shall contain a complete listing of test equipment with make and
`model number and a detailed check-off sheet. The list of test equipment shall
`include instrument accuracy and calibration dates. All equipment shall be
`calibrated in accordance with the manufacturer’s instructions. There shall be no
`contradictions between the Laboratory Test Procedure and the contractor’s in-
`house test procedure. Written approval of the in-house test procedures shall be
`obtained from the COTR before initiating the compliance test program. The
`OVSC Laboratory Test Procedures are not intended to limit or restrain a
`contractor from developing or utilizing any testing techniques or equipment which
`will assist in procuring the required compliance test data. These Laboratory Test
`Procedures do not constitute an endorsement or recommendation for use of any
`product or method. However, the application of any such testing technique or
`equipment is subject to prior approval of the COTR.
`
`NOTE: The OVSC Laboratory Test Procedures, prepared for the limited purpose
`of use by independent laboratories under contract to conduct compliance tests
`for the OVSC, are not rules, regulations or NHTSA interpretations regarding the
`meaning of a FMVSS. The Laboratory Test Procedures are not intended to limit
`the requirements of the applicable FMVSS(s). In some cases, the OVSC
`Laboratory Test Procedures do not include all of the various FMVSS minimum
`performance requirements. Recognizing applicable test tolerances, the
`Laboratory Test Procedures may specify test conditions that are less severe than
`the minimum requirements of the standard. In addition, the Laboratory Test
`Procedures may be modified by
`

`PURPOSE AND APPLICATION....Continued
`
`the OVSC at any time without notice, and the COTR may direct or authorize
`contractors to deviate from these procedures, as long as the tests are performed
`in a manner consistent with the standard itself and within the scope of the
`contract. Laboratory Test Procedures may not be relied upon to create any right
`or benefit in any person. Therefore, compliance of a vehicle or item of motor
`vehicle equipment is not necessarily guaranteed if the manufacturer limits its
`certification tests to those described in the OVSC Laboratory Test Procedures.
`
`GENERAL REQUIREMENTS
`
`FMVSS 111 specifies requirements for the performance and location of rearview
`mirrors.
`
`REQUIREMENTS FOR PASSENGER CARS
`
`Each passenger car shall have an inside rearview mirror of unit magnification
`with the required field-of-view and a driver's side outside rearview mirror of unit
`magnification with the required field-of-view. If the inside rearview mirror does
`not meet the field-of-view requirements, an outside rearview mirror of unit
`magnification or a convex mirror (with required markings) is required on the
`passenger's side. The average radius of curvature of the convex mirror shall be
`not less than 889 millimeters (mm) and not more than 1,651 mm. All the required
`mirrors must be adjustable in both the vertical and horizontal directions and have
`a stable mounting.
`
`REQUIREMENTS FOR MPVs, TRUCKS AND BUSES (OTHER THAN SCHOOL
`BUSES) WITH A GVWR 4,536 KILOGRAMS
`
`A.
`
`B.
`
`Mirrors as described for passenger cars, OR
`
`Unit magnification outside mirrors on both sides of the vehicle with stable
`supports, adjustable in both the vertical and horizontal directions, and with
`reflective surface of at least 126 square centimeters (cm2).

`
`GENERAL REQUIREMENTS....Continued
`
`REQUIREMENTS FOR MPVs, TRUCKS AND BUSES (OTHER THAN SCHOOL
`BUSES) WITH A GVWR > 4,536 KILOGRAMS (Kg)
`
`Each vehicle shall have outside mirrors of unit magnification, each with not less
`than 323 cm2 of reflective surface, installed with stable supports on both sides of
`the vehicle. The mirrors shall be located so as to provide the driver a view to the
`rear along both sides of the vehicle and shall be adjustable both in the horizontal
`and vertical directions to view the rearward scene.
`
`REQUIREMENTS FOR SCHOOL BUSES
`
`Refer to the latest version of TP-111SB-00 for testing school bus mirror systems.
`
`TEST DATA LOSS
`
`A compliance test is not to be conducted unless all of the various test conditions
`specified in the applicable OVSC Laboratory Test Procedure have been met.
`Failure of a contractor to obtain the required test data and to maintain acceptable
`limits on test parameters in the manner outlined in the applicable OVSC
`Laboratory Test Procedure may require a retest at the expense of the contractor.
`The retest costs will include the cost of leasing a replacement vehicle and all
`costs associated with conducting the retest. The original test specimen (vehicle
`or equipment item) used for the invalid test shall remain the property of OVSC,
`and the retest specimen shall remain the property of the contractor. If there is a
`test failure, the contractor shall retain the retest specimen for a period not
`exceeding 180 days. If there is no test failure, the Contractor may dispose of the
`test specimen upon notification from the COTR that the final test report has been
`accepted.
`
`The Contracting Officer of NHTSA is the only NHTSA official authorized to notify
`the contractor that a retest is required. The retest shall be completed within two
`(2) weeks after receipt of notification by the Contracting Officer that a retest is
`required. If a retest is conducted, no test report is required for the original test.

`The contractor shall provide appropriate security measures to protect the OVSC
`test vehicles from unauthorized personnel during the entire compliance testing
`program. The contractor is financially responsible for any acts of theft and/or
`vandalism which occur during the storage of test vehicles. Any security problems
`which arise shall be reported by telephone to the Industrial Property Manager
`(IPM), Office of Contracts and Procurement, within two working days after the
`incident. A letter containing specific details of the security problem will be sent to
`the IPM (with copy to the COTR) within 48 hours. The contractor shall protect
`and segregate the data that evolves from compliance testing before and after
`each vehicle test. No information concerning the vehicle safety compliance
`testing program, shall be released to anyone except the COTR, unless
`specifically authorized by the COTR or the COTR's Branch Chief or Division
`Chief.
`
`NOTE: NO INDIVIDUALS, OTHER THAN CONTRACTOR PERSONNEL
`DIRECTLY INVOLVED IN THE COMPLIANCE TESTING PROGRAM OR OVSC
`PERSONNEL, SHALL BE ALLOWED TO WITNESS ANY VEHICLE
`COMPLIANCE TEST UNLESS SPECIFICALLY AUTHORIZED BY THE COTR.
`
`GOOD HOUSEKEEPING
`
`Contractors shall maintain the entire vehicle compliance testing area, test fixtures
`and instrumentation in a neat, clean and painted condition with test instruments
`arranged in an orderly manner consistent with good test laboratory housekeeping
`practices.
`
`TEST SCHEDULING AND MONITORING
`
`The contractor shall submit a vehicle test schedule to the COTR prior to
`conducting the first compliance test. Tests shall be completed as required in the
`contract.
`
`Scheduling of vehicle tests shall be adjusted to permit vehicles to be tested to
`other FMVSSs as may be required by the OVSC. All vehicle compliance testing
`shall be coordinated with the COTR in order to allow monitoring by the COTR
`and/or other OVSC personnel if desired.

`As a general rule, use of the metric system of weights and measures is preferred.
`Performance parameters and test conditions in FMVSS 111 are now specified in
`metric units. In this Laboratory Test Procedure metric values are followed by
`English units only for reference (not necessarily equal). If test equipment is not
`available for direct measurement in metric units, the test laboratory shall
`calculate the exact metric equivalent by means of a conversion factor carried out
`to at least 5 significant digits before rounding consistent with the specified metric
`requirement. Metric units shall be used in Final Test Reports.

`
`PROCEDURE
`
`
`
`The general procedure is to position the viewing instrument using
`an appropriate fixture at the left and right eye point locations
`respectively and to view the field-of-view grid and markers placed
`at a specified distance behind the vehicle. The required field-of-
`view measurements are then made and calculations performed as
`required to evaluate compliance with the standard. Refer to
`Figure 2.

`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`(A) Maneuver the vehicle onto a predetermined location on the
`level floor of the test laboratory. This location will also be
`used for the driver side and passenger side outside mirror
`testing.
`
`(B)
`
`Establish a vertical longitudinal plane tangent to the widest
`point of the test vehicle on the driver’s side (parallel to the
`centerline of the vehicle) and locate its intersection with the
`floor.
`
`(C) Measure 10.7 meters (35 feet) to rear of the driver’s eye
`location provided by the COTR and set up a field-of-view test
`screen perpendicular to the tangent plane. Screen should
`be grid format with lines equally spaced and delineated with
`letters and numbers for reference purposes.
`
`
`
`
`
`
`
`
`
`(D)
`
`(E)
`
`Load the vehicle to simulate the driver and four passengers
`(unless capacity is less) with ballast of 68 kilograms
`(150 pounds) per occupant.
`
`Block and secure the vehicle in place to eliminate vertical or
`horizontal motion during the test and to maintain vehicle
`position when the load is removed. Measure and record in
`the general test log the vehicle orientation for future
`reference.

`
`Remove the front seat(s) and install the viewing instrument
`positioning fixture. The viewing instrument shall be located
`using the fixture such that the focal point of the instrument is
`in the position of the driver eye point location provided by the
`COTR. The viewing instrument and fixture shall be designed
`such that the viewing instrument can be rotated about the
`vertical axis.

`
`(H) While observing through the viewing instrument, adjust the
`inside mirror both horizontally and vertically such that the Z2
`target is visible on the TOP EDGE of the mirror on the mirror
`centerline. Once the mirror is adjusted it should not be
`altered until the end of the inside mirror test.
`
`(I) While observing through the viewing instrument, have an
`assistant place a target on the vehicle centerline on the field-
`of-view screen at a vertical height Z1 at a location where the
`target appears at the LOWER edge of the mirror. This point
`will be used to calculate the distance at which the level road
`surface would be first visible.
`
`(J) While observing through the instrument in the driver’s left
`eye location, have an assistant place markers on the field-of-
`view screen at the extreme left and right sides of the mirror
`view. Repeat while observing from the driver’s right eye
`location. Take photographs of the left and right eye views
`through the viewing instrument. In addition, photograph the
`field-of-view grid with all markers shown.
`
`Record the following on Data Sheet 3.
`
`
`
`YRR - The maximum lateral distance to the driver's right of
`the center line that is viewed on the grid with the
`instrument in the right eye location.

`
`NOTE: The YRL and YLR lateral distances provide the widest
`field-of-view.
`
`(K) With the positioning fixture still in position, measure the
`distance from the midpoint between the driver eye point
`locations to the center of the mirror surface. Establish the
`location of the imaginary projected eye point on a horizontal
`plane forward of the mirror surface at a distance E equal to
`the measured distance.

`
`REQUIREMENTS (S5.2)
`
`
`
`Each passenger car shall have an outside mirror of unit
`magnification. The mirror shall provide the driver a view of a level
`road surface extending to the horizon from a line, perpendicular to
`a longitudinal plane tangent to the driver's side of the vehicle at the
`widest point, extending 2.4 meters (8 feet) out from the tangent
`plane 10.7 meters (35 feet) behind the driver's eyes, with the seat
`in the rearmost position. The line of sight may be partially obscured
`by rear body or fender contours. (S5.2.1)
`
`

`

`18
`
`Neither the mirror nor the mounting shall protrude farther than the
`widest part of the vehicle body except to the extent necessary to
`produce a field of view meeting or exceeding the requirements of
`S5.2.1. The mirror shall not be obscured by the un-wiped portion of
`the windshield. (S5.2.2)
