3 Hardware Standards
3.1 Scope
This section contains the requirements for the machines and manufactured devices
that are part of a voting system. It specifies minimum values for certain performance
characteristics; physical characteristics; and design, construction, and maintenance
characteristics for the hardware and selected related components of all voting systems,
such as:
Ballot printers;
Ballot cards and sheets;
Ballot displays;
Voting devices, including punching and marking devices and DRE recording
devices;
Voting booths and enclosures;
Ballot boxes and ballot transfer boxes;
Ballot readers;
Computers used to prepare ballots, program elections, consolidate and report
votes, and perform other elections management activities;
Electronic ballot recorders;
Electronic precinct vote control units;
Removable electronic data storage media;
Servers; and
Printers.
This section applies to the combination of software and hardware to accomplish
specific performance and system control requirements. Standards that are specific to
software alone are provided in Section 4 of the Standards.
3-1 Volume I Section 3
Hardware Standards
3.1.1 Hardware Sources
The requirements of this section apply generally to all hardware used in voting
systems, including:
a. Hardware provided by the voting system vendor and its suppliers;
b. Hardware furnished by an external provider (for example, providers of
commercial off-the-shelf (COTS) machines and devices) where the hardware
may be used in any way during voting system operation; and
c. Hardware provided by the voting jurisdiction.
3.1.2 Organization of this Section
The standards presented in this section are organized as follows:
Performance Requirements: These requirements address the combined
operational capabilities of the voting system's hardware and software across a
broad range of parameters;
Physical Requirements: These requirements address the size, weight and
transportability of the voting system; and
Design, Construction, and Maintenance Requirements: These requirements
address the reliability and durability of materials, product marking, quality of
system workmanship, safety, and other attributes to ensure smooth system
operation in the voting environment.
3.2 Performance Requirements
The performance requirements address a broad range of parameters, encompassing:
a. Accuracy requirements, where requirements are specified for distinct
processing functions of paper-based and DRE systems;
b. Environmental requirements, where no distinction is made between
requirements for paper-based and DRE systems, but requirements for precinct
and central count are described;
c. Vote data management requirements, where no differentiation is made
between requirements for paper-based and DRE systems;
3-2 Volume I Section 3
Hardware Standards
d. Vote recording requirements, where separate and distinct requirements are
delineated for paper-based and DRE systems;
e. Conversion requirements, which apply only to paper-based systems;
f. Processing requirements, where separate and distinct requirements are
delineated for paper-based and DRE systems; and
g. Reporting requirements, where no distinction is made between requirements
for paper-based and DRE systems, but where differences between precinct
and central count systems are readily apparent based on differences of their
reporting.
The performance requirements include such attributes as ballot reading and handling
requirements; system accuracy; memory stability; and the ability to withstand specified
environmental conditions. These characteristics also encompass system-wide
requirements for shelter, electrical supply, and compatibility with data networks.
Performance requirements for voting systems represent the combined operational
capability of both system hardware and software. Accuracy, as measured by data
error rate, and operational failure are treated as distinct attributes in performance
testing. All systems shall meet the performance requirements under operating
conditions and after storage under non-operating conditions.
3.2.1 Accuracy Requirements
Voting system accuracy addresses the accuracy of data for each of the individual
ballot positions that could be selected by a voter, including the positions that are not
selected. For a voting system, accuracy is defined as the ability of the system to
capture, record, store, consolidate and report the specific selections and absence of
selections, made by the voter for each ballot position without error. Required accuracy
is defined in terms of an error rate that for testing purposes represents the maximum
number of errors allowed while processing a specified volume of data. This rate is set
at a sufficiently stringent level such that the likelihood of voting system errors affecting
the outcome of an election is exceptionally remote even in the closest of elections.
The error rate is defined using a convention that recognizes differences in how vote
data is processed by different types of voting systems. Paper-based and DRE systems
have different processing steps. Some differences also exist between precinct count
and central count systems. Therefore, the acceptable error rate applies separately and
distinctly to each of the following functions:
a. For all paper-based systems:
1) Scanning ballot positions on paper ballots to detect selections for individual
candidates and contests;
3-3 Volume I Section 3
Hardware Standards
2) Conversion of selections detected on paper ballots into digital data;
b. For all DRE systems:
1) Recording the voter selections of candidates and contests into voting data
storage; and
2) Independently from voting data storage, recording voter selections of
candidates and contests into ballot image storage.
c. For precinct-count systems (paper-based and DRE):
Consolidation of vote selection data from multiple precinct-based systems to
generate jurisdiction-wide vote counts, including storage and reporting of the
consolidated vote data; and
d. For central-count systems (paper-based and DRE):
Consolidation of vote selection data from multiple counting devices to generate
jurisdiction-wide vote counts, including storage and reporting of the
consolidated vote data.
For testing purposes, the acceptable error rate is defined using two parameters: the
desired error rate to be achieved, and the maximum error rate that should be accepted
by the test process.
For each processing function indicated above, the system shall achieve a target error
rate of no more than one in 10,000,000 ballot positions, with a maximum acceptable
error rate in the test process of one in 500,000 ballot positions.
3.2.2 Environmental Requirements
The environmental requirements for voting systems include shelter, space, furnishings
and fixtures, supplied energy, environmental control , and external telecommunications
services. Environmental conditions applicable to the design and operation of voting
systems consist of the following categories:
Natural environment, including temperature, humidity, and atmospheric
pressure;
Induced environment, including proper and improper operation and handling of
the system and its components during the election processes;
Transportation and storage; and
Electromagnetic signal environment, including exposure to and generation of
radio frequency energy.

3-21 Volume I Section 3
Hardware Standards
3.4 Design, Construction, and Maintenance
Characteristics
This section covers voting system materials, construction workmanship, and specific
design characteristics important to the successful operation and efficient maintenance
of the system.
3.4.1 Materials, Processes, and Parts
The approach to system design is unrestricted, and may incorporate any form or
variant of technology capable of meeting the voting systems requirements and
standards.
Precinct count systems shall be designed in accordance with best commercial practice
for microcomputers, process controllers, and their peripheral components. Central
count voting systems and equipment used in a central tabulating environment shall be
designed in accordance with best commercial and industrial practice.
All voting systems shall:
a. Be designed and constructed so that the frequency of equipment malfunctions
and maintenance requirements are reduced to the lowest level consistent with
cost constraints;
b. Include, as part of the accompanying TDP, an approved parts list; and
c. Exclude parts or components not included in the approved parts list.
3.4.2 Durability
All voting systems shall be designed to withstand normal use without deterioration and
without excessive maintenance cost for a period of ten years.
3.4.3 Reliability
The reliability of voting system devices shall be measured as mean time between
Failure (MTBF) for the system submitted for testing. MBTF is defined as the value of
the ratio of operating time to the number of failures which have occurred in the
3-22 Volume I Section 3
Hardware Standards
specified time interval. A typical system operations scenario consist of approximately
45 hours of equipment operation, consisting of 30 hours of equipment set-up and
readiness testing and 15 hours of elections operations. For the purpose of
demonstrating compliance with this requirement, a failure is defined as any event
which results in either the:
a. Loss of one or more functions; or
b. Degradation of performance such that the device is unable to perform its
intended function for longer than 10 seconds.
The MTBF demonstrated during qualification testing shall be at least 163 hours.
3.4.4 Maintainability
Maintainability represents the ease with which maintenance actions can be performed
based on the design characteristics of equipment and software and the processes the
vendor and election officials have in place for preventing failures and for reacting to
failures. Maintainability includes the ability of equipment and software to self-diagnose
problems and make non-technical election workers aware of a problem. Maintainability
addresses all scheduled and unscheduled events, which are performed to:
· Determine the operational status of the system or a component;
· Adjust, align, tune, or service components;
· Repair or replace a component having a specified operating life or
replacement interval;
· Repair or replace a component that exhibits an undesirable predetermined
physical condition or performance degradation;
· Repair or replace a component that has failed; and
· Verify the restoration of a component, or the system, to operational status.
Maintainability shall be determined based on the presence of specific physical
attributes that aid system maintenance activities, and the ease with which system
maintenance tasks can be performed by the ITA. Although a more quantitative basis
for assessing maintainability, such as the mean to repair the system is desirable, the
qualification of a system is conducted before it is approved for sale and thus before a
broader base of maintenance experience can be obtained.
3.4.4.1 Physical Attributes
The following physical attributes will be examined to assess reliability:
3-23 Volume I Section 3
Hardware Standards
a. Presence of labels and the identification of test points;
b. Provision of built-in test and diagnostic circuitry or physical indicators of
condition;
c. Presence of labels and alarms related to failures; and
d. Presence of features that allow non-technicians to perform routine
maintenance tasks (such as update of the system database).
3.4.4.2 Additional Attributes
The following additional attributes will be considered to assess system maintainability.
a. Ease of detecting that equipment has failed by a non-technician;
b. Ease of diagnosing problems by a trained technician;
c. Low false alarm rates (i.e., indications of problems that do not exist);
d. Ease of access to components for replacement;
e. Ease with which adjustment and alignment can be performed;
f. Ease with which database updates can be performed by a non-technician; and
g. Adjust, align, tune, or service components.
3.4.5 Availability
The availability of a voting system is defined as the probability that the equipment (and
supporting software) needed to perform designated voting functions will respond to
operational commands and accomplish the function. The voting system shall meet the
availability standard for each of the following voting functions:
a. For all paper-based systems:
1) Recording voter selections (such as by ballot marking or punch); and
2) Scanning the punches or marks on paper ballots and converting them into
digital data;
b. For all DRE systems, recording and storing the voter's ballot selections.
c. For precinct-count systems (paper-based and DRE), consolidation of vote
selection data from multiple precinct-based systems to generate jurisdiction-
3-24 Volume I Section 3
Hardware Standards
wide vote counts, including storage and reporting of the consolidated vote data;
and
d. For central-count systems (paper-based and DRE), consolidation of vote
selection data from multiple counting devices to generate jurisdiction-wide vote
counts, including storage and reporting of the consolidated vote data.
System availability is measured as the ratio of the time during which the system is
operational a (up time) to the total time period of operation (up time plus down time).
Inherent availability (Ai) is a the fraction of time a system is functional, based upon
Mean Time Between Failure (MTBF) and Mean Time to Repair (MTTR), that is:
Ai = (MTBF)/(MTBF + MTTR)
Mean Time to Repair (MTTR) is the average time required to perform a corrective
maintenance task during periods of system operation. Corrective maintenance task
time is active repair time, plus the time attributable to other factors that could lead to
logistic or administrative delays, such as travel notification of qualified maintenance
personnel and travel time for such personnel to arrive at the appropriate site.
Corrective maintenance may consist of substitution of the complete device or one of its
components, as in the case of precinct count and some central count systems, or it
may consist of on-site repair.
The voting system shall achieve at least ninety nine percent availability during normal
operation for the functions indicated above. This standard encompasses for each
function the combination of all devices and components that support the function,
including their MTTR and MTBF attribute.
Vendors shall specify the typical system configuration that is to be used to assess
availability, and any assumptions made with regard to any parameters that impact the
MTTR. These factors shall include at a minimum:
a. Recommended number and locations of spare devices or components to be
kept on hand for repair purposes during periods of system operation;
b. Recommended number and locations of qualified maintenance personnel who
need to be available to support repair calls during system operation; and
c. Organizational affiliation (i.e., jurisdiction, vendor) of qualified maintenance
personnel.
3.4.6 Product Marking

a. Adopt and adhere to practices and procedures to ensure that their products
are free from damage or defect that could make them unsatisfactory for their
intended purpose; and
b. Ensure that components provided by external suppliers are free from damage
or defect that could make them unsatisfactory for their intended purpose.
3.4.8 Safety
All voting systems shall meet the following requirements for safety:
a. All voting systems and their components shall be designed so as to eliminate
hazards to personnel, or to the equipment itself;
b. Defects in design and construction that can result in personal injury or
equipment damage must be detected and corrected before voting systems and
components are placed into service; and
c. Equipment design for personnel safety shall be equal to or better than the
appropriate requirements of the Occupational Safety and Health Act (OSHA),
as identified in Title 29, part 1910, of the Code of Federal Regulations.
