Standard Test Method for Measuring the Performance of Personal Cooling Systems Using Physiological Testing

Standard Test Method for Measuring the Performance of Personal Cooling Systems Using Physiological Testing

SIGNIFICANCE AND USE
This test method can be used to quantify and compare the cooling provided by different Personal Cooling Systems (PCS) worn with a standard outer garment or with a specified protective outer garment.
4.1.1 This test method will assess the performance of PCS based on the physiological measurement of core temperature, mean skin temperature, heart rate, exposure time, oxygen consumption, and whole body sweat rate.
Evaluating the effectiveness of PCS is an extremely complicated endeavor that involves many factors related to thermal exchange between the PCS, the environment, and the participant. It would not be practical in a test method of this scope to establish details sufficient to cover all contingencies. Therefore, a valid physiological method of measuring core temperature, along with other variables of thermal strain, provides an acceptable means of classifying the performance of PCS. This test method will also measure the amount of time the PCS maintains core temperature within safe limits during a specified condition of thermal stress.
Departures from the instructions in this test method may lead to significantly different test results. Technical knowledge concerning thermoregulatory responses, the theory of heat transfer, physiological and environmental temperature measurement, and testing practices is needed to evaluate which departures from the instructions given in this test method are significant. All departures must be reported with the results.
SCOPE
1.1 This test method covers the physiological measurement of internal body core temperature, skin temperature, thermal exposure time, heart rate response, oxygen consumption, and whole body sweat rate, to assess the effectiveness of Personal Cooling Systems in reducing the effects of thermal stress.
1.1.1 To increase safety during physiological testing, this dynamic test requires the use of human participants who exhibit specific health and physical fitness requirements.
1.2 This test incorporates the use of protective clothing ensembles (outer garments) used in conjunction with or worn over top of the PCS. This scope is therefore oriented to industrial rather than athletic applications.
1.2.1 The effectiveness of different PCS will be quantified with the same protective clothing ensemble. Therefore, the physiological values obtained apply only to the cooling systems, the particular protective outer garment, and the specific test conditions.
1.2.2 When a protective outer garment is not provided, this test method requires that PCS shall be tested with the standard outer garment defined within this test method.
1.2.3 The present standard does not attempt to determine important clothing characteristics, such as thermal insulation and evaporative resistance, of the PCS or of the garments worn with the PCS. Test Method F 1291 can be referenced for clothing measurements.
1.3 The values stated in this test method shall be SI units.
1.4 It is the responsibility of the test laboratory to obtain the necessary and appropriate approval(s) required by their institution for conducting tests using human participants.
1.5 This test method 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 test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Individuals in various occupations are exposed to high heat stress resulting from increased
metabolism, or the environment, or both. Environmental heat stress can be especially severe when
individuals are required to wear Personal Protective Equipment (PPE), which impairs or prevents
evaporation of sweat from the skin, and thus nullifies the body’s principal means of removing
metabolic heat. Failure to dissipate this heat can dramatically limit work capacity and heat tolerance,
thereby increasing the risk of heat-related illness. To reduce this risk, workers are wearing Personal
Cooling Systems (PCS) to extend their exposure time to thermal stress. These systems are intended
to limit the effects of external environmental heat and the internally generated metabolic heat on the
body. For this purpose, standards that objectively quantify the effectiveness of PCS are essential.
Therefore,teststhatmeasureimportantphysiologicalvariables,suchascoretemperature,areessential
in evaluating PCS applications and increasing worker’s health and safety.

ASTM F2371-16(Test Method)
Standard Test Method for Measuring the Heat Removal Rate of Personal Cooling Systems Using a Sweating Heated Manikin

SIGNIFICANCE AND USE
4.1 This test method can be used to quantify and compare the cooling provided by different personal cooling systems (PCS) worn with a common base ensemble. Any base ensemble can be selected based on the intended end use of the PCS.  
4.1.1 The test method is intended to allow garments based on various cooling technologies to be evaluated fairly and objectively, by taking into account both dry and evaporative heat transfer.  
4.2 The measurements of heat removal rates and duration of cooling provided by the PCS depend on the apparatus, the base ensemble, and the techniques used.  
4.2.1 Departures from the instructions in this test method will potentially lead to significantly different test results.  
4.2.2 Technical knowledge concerning the theory of heat transfer, temperature, air motion measurement, humidity, evaporative cooling, and testing practices is needed to evaluate which departures from the instructions given in this test method are significant. Report any departures with the results.
SCOPE
1.1 This test method uses a sweating manikin in an environmental chamber to measure the heat removal rate and cooling duration provided by a personal cooling garment worn with a base ensemble.2  
1.1.1 The use of a sweating heated manikin is essential because of the potentially large amount of heat dissipation from the body associated with evaporative cooling.  
1.2 The experimental values obtained for the cooling rates and cooling duration apply only to the particular PCS and additional garments worn during the test and for the environmental conditions used.  
1.2.1 It is feasible that this test method will yield unrealistically high cooling rates for ambient air circulation systems since the manikin’s surface stays continuously saturated during the test and the relative humidity in the chamber is relatively low; consequently the convective and evaporative heat loss rates from the body to the environment are probably higher from the manikin than they would be from a human, particularly in environments with higher levels of humidity.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Exoskeleton Use: Confined Space: Horizontal Movement

SIGNIFICANCE AND USE
5.1 Exoskeletons are being used in the industrial, military, response, medical, and recreational sectors to enhance safety and effectiveness of the user to perform tasks. Confined spaces exist in many of these areas, as shown in Fig. 1, requiring people to fit through small spaces and this is potentially even more difficult while wearing an exoskeleton. For example, in the automobile manufacturing industry, workers wearing exoskeletons are required to fit into a confined automobile door opening while carrying tools to attach components to the car body. In emergency response operations, exoskeletons are used to enhance the safety and effectiveness of emergency responders operating in hazardous and confined space environments for search and rescue of victims. The testing results of exoskeletons shall describe, in a statistically significant way, how reliably the exoskeleton is able to support tasks within the specified types of environments, confinements, and terrains, and thus provide sufficiently high levels of confidence to determine the applicability of the exoskeleton.  
5.2 This test method addresses exoskeleton safety and performance requirements expressed by emergency responders, military, manufacturing, or other organizations requesting this test. The safety and performance data captured within this test method are indicative of the test exoskeleton’s and the exoskeleton user’s (see 9.6.6) capabilities. The safety and performance data from these tests are essential to guiding the procurement and deployment decisions of exoskeleton purchasers and users.  
5.3 A standard artifact is specified to be easily fabricated. This facilitates evaluation by exoskeleton developers, manufacturers, and users, and to provide replication of confined space: horizontal movement tests across the exoskeleton sectors. The artifact can also be used to support training (see Practice F3444/F3444M) and to establish proficiency of exoskeleton users, as well as provide manufacturers w...
SCOPE
1.1 Purpose:  
1.1.1 The purpose of this test method, as a part of a suite of exoskeleton use test methods, is to quantitatively evaluate an exoskeleton’s (see Terminology F3323) performance or safety of usage, or both, by the exoskeleton user (see 1.4) in confined spaces with horizontal user movement.  
1.1.2 Exoskeletons shall possess a certain set of allowable exoskeleton user movement capabilities, including user-motion adaptability, to suit operations such as: industrial, military, response, medical, or recreational. Environments in these typical sectors often pose constraints to exoskeleton user movement to various degrees. Being able to pass-through or maneuver, or both, effectively in confined spaces is essential for exoskeleton deployment for a variety of tasks. This test method specifies apparatuses to standardize this confined space task for testing exoskeleton user movement along the horizontal axis.  
1.1.3 Exoskeletons shall be able to handle many types of task and terrain complexities. The required movement capabilities include, for example: walking, running, crawling, climbing, traversing gaps, hurdles, stairs, slopes, various types of floor surfaces or terrains, and confined spaces. Standard test methods are required to evaluate whether or not exoskeletons meet these requirements.  
1.1.4 ASTM Subcommittee F48.03 develops and maintains international standards for task performance and environmental considerations that include but are not limited to, standards for safety, quality, and efficiency. This subcommittee aims to develop standards for any exoskeleton application as exemplified as in 1.1.2. The F48.03 test suite consists of a set of test methods for evaluating exoskeleton capability requirements. This confined space: horizontal movement test method is a part of the test suite. The apparatuses associated with the test methods challenge specific exoskeleton capabilities in repeatable ways to fac...

1.1 This guide is intended to assist in the integration of ergonomic principles into the design and planning of new occupational systems from the earliest design stages through implementation. Doing so may reduce or eliminate the necessity for later redesign that could have been foreseen.  
1.2 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.  
1.3 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.

ASTM
ASTM F2371-16(Test Method)
Standard Test Method for Measuring the Heat Removal Rate of Personal Cooling Systems Using a Sweating Heated Manikin

SIGNIFICANCE AND USE
4.1 This test method can be used to quantify and compare the cooling provided by different personal cooling systems (PCS) worn with a common base ensemble. Any base ensemble can be selected based on the intended end use of the PCS.  
4.1.1 The test method is intended to allow garments based on various cooling technologies to be evaluated fairly and objectively, by taking into account both dry and evaporative heat transfer.  
4.2 The measurements of heat removal rates and duration of cooling provided by the PCS depend on the apparatus, the base ensemble, and the techniques used.  
4.2.1 Departures from the instructions in this test method will potentially lead to significantly different test results.  
4.2.2 Technical knowledge concerning the theory of heat transfer, temperature, air motion measurement, humidity, evaporative cooling, and testing practices is needed to evaluate which departures from the instructions given in this test method are significant. Report any departures with the results.
SCOPE
1.1 This test method uses a sweating manikin in an environmental chamber to measure the heat removal rate and cooling duration provided by a personal cooling garment worn with a base ensemble.2  
1.1.1 The use of a sweating heated manikin is essential because of the potentially large amount of heat dissipation from the body associated with evaporative cooling.  
1.2 The experimental values obtained for the cooling rates and cooling duration apply only to the particular PCS and additional garments worn during the test and for the environmental conditions used.  
1.2.1 It is feasible that this test method will yield unrealistically high cooling rates for ambient air circulation systems since the manikin’s surface stays continuously saturated during the test and the relative humidity in the chamber is relatively low; consequently the convective and evaporative heat loss rates from the body to the environment are probably higher from the manikin than they would be from a human, particularly in environments with higher levels of humidity.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM
ASTM F1210-23(Guide)
Standard Guide for Ecological Considerations for the Use of Oil Spill Dispersants in Freshwater and Other Inland Environments, Lakes and Large Water Bodies

SIGNIFICANCE AND USE
3.1 This guide is meant to aid response teams who may use it during spill response planning and spill events.  
3.2 This guide should be adapted to site specific circumstance.
SCOPE
1.1 This guide covers the use of oil spill dispersants to assist in the control of oil spills. The guide is written with the goal of minimizing the environmental impacts of oil spills; this goal is the basis on which the recommendations are made. Aesthetic and socioeconomic factors are not considered, although these and other factors are often important in spill response.  
1.2 Spill responders have available several means to control or clean up spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This is a general guide only. Oil, as used in this guide, includes crude oils and refined petroleum products. Differences between individual dispersants or between different oil products are not considered. The dispersibility of the oil with the chosen dispersant should be evaluated.  
1.4 The guide is organized by habitat type, for example, small ponds and lakes, rivers and streams, and land. It considers the use of dispersants primarily to protect habitats from impact (or to minimize impacts).  
1.5 This guide applies only to freshwater and other inland environments. It does not consider the direct application of dispersants to subsurface waters.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 This guide does not address getting regulatory approval.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 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.  
1.10 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.
