Standard Practice for Recording Environmental Effects for Utilization with A-UGV Test Methods
SIGNIFICANCE AND USE
4.1 Lighting:
4.1.1 Various lighting conditions can potentially affect A-UGV optical sensor performance by affecting sensor and in turn, A-UGV responsiveness. Lighting sources can include ambient lighting as well as light emitters associated A-UGV operation. Two setups for lighting include direct and indirect source applied to the A-UGV. Direct lighting can also include reflected light from a highly reflective surface and implies that the source is directed at the light-affected components of the A-UGV (for example, sensors). Indirect or ambient light includes lighting where the source is not directly applied to the light-affected components of the A-UGV. Lighting exposure is either continuous light applied to the A-UGV or transitional in which the vehicle passes through various lighting conditions and levels. Light intensity is divided into five levels exemplified through dark, typical indoor lighting, and full sunlight.
4.1.2 Ambient Lighting Type:
4.1.2.1 Exposed bulb,
4.1.2.2 Spotlight,
4.1.2.3 Sunlight,
4.1.2.4 Reflected,
4.1.2.5 Light from another vehicle,
4.1.2.6 Laser,
4.1.2.7 Filtered.
4.1.3 Ambient Lighting Source:
4.1.3.1 Direct Highly-Concentrated, Directional Lighting,
4.1.3.2 Indirect and Diffused.
4.1.4 Ambient Lighting Source Location—Record light source location and elevation with respect to the vehicle (refer to Fig. 1).

SCOPE
1.1 This practice describes a means to record the following environmental conditions that may affect the performance of A-UGVs: lighting, external sensor emission, temperature, ground surface, air quality, humidity, and electrical interference.
1.2 The A-UGV operating ranges for each of the conditions listed in 1.1 are described and parameterized in Section 4 and allow a basis for performance comparison in test methods. The approach is to divide the list of environmental conditions into sub-conditions that represent the various aspects of the major category (for example, sunlight within ambient lighting). Where necessary, this practice also provides guidelines (for example, lighting direction) to record environmental conditions in an existing environment.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are not precise mathematical conversion to imperial units. They are close approximate equivalents for the purpose of specifying material dimensions or quantities that are readily available to avoid excessive fabrication costs of test apparatuses while maintaining repeatability and reproducibility of the test method results. These values given in parentheses are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

play in the A-UGV performance. Various A-UGVs are designed to be operated both indoors and
outdoors under conditions specified by the manufacturer. Likewise, end users of the A-UGV will be
operating these vehicles in a variety of environmental conditions. When conducting and replicating
Committee F45 test methods by vehicle manufacturers and users, it is important to specify and record
the environmental conditions under which the A-UGV is tested as there will be variations in vehicle
performance caused by the conditions, especially when comparing and replicating sets of test results.
It is also important to consider changes in environmental conditions during the course of operations
(for example, transitions between conditions). As such, environmental conditions specified in this
practice are both continuous and transitional; with the A-UGV stationary or in motion. This practice
provides brief introduction to the following list of environmental conditions that can affect
performance of the A-UGV: lighting, external sensor emission, temperature, humidity, electrical
interference, ground surface, air quality.
This practice then breaks down each condition into sub-categories so that the user can record the
various aspects associated with the category when conductingA-UGVtests defined in Committee F45
Test Methods , , those listed in the Related Materials section, and Terminology F3200.Itis
recommended that salient environment conditions be recorded when conducting Committee F45 test
methods, but is not required.
