ASTM F1862/F1862M-17(Test Method)
Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Known Velocity)

SIGNIFICANCE AND USE
5.1 This test method offers a procedure for evaluating medical face mask resistance to synthetic blood penetration that is useful in establishing claims for penetration resistance performance of medical face masks and ranking their performance. However, this test method does not define acceptable levels of penetration resistance because this determination must be made by each responsible user organization based on its own specific application and conditions. Therefore, when using this test method to make claims for the performance of medical face masks, the specific conditions under which testing is conducted must be described.  
5.2 Medical face masks are intended to resist liquid penetration from the splatter or splashing of blood, body fluids, and other potentially infectious materials. Many factors affect the wetting and penetration characteristics of body fluids, such as surface tension, viscosity, and polarity of the fluid, as well as the structure and relative hydrophilicity or hydrophobicity of the materials and the design of the mask itself. The surface tension range for blood and body fluids (excluding saliva) is approximately 0.042 to 0.060 N/m.7 To help simulate the wetting characteristics of blood and body fluids, the surface tension of the synthetic blood is adjusted to approximate the lower end of this surface tension range. The resulting surface tension of the synthetic blood is 0.042 ± 0.002 N/m.  
5.3 The synthetic blood mixture is prepared with a red dye to aid in visual detection and a thickening agent to simulate the flow characteristics of blood. The synthetic blood will not always duplicate the polarity, and thus the wetting behavior and subsequent penetration, of real blood and other body fluids through protective clothing materials.  
5.4 During a medical procedure, a blood vessel is occasionally punctured resulting in a high velocity stream of blood impacting a protective medical face mask. The impact velocity depends on several factors,...
SCOPE
1.1 This test method is used to evaluate the resistance of medical face masks to penetration by the impact of a small volume (~2 mL) of a high-velocity stream of synthetic blood. Medical face mask pass/fail determinations are based on visual detection of synthetic blood penetration.  
1.2 This test method does not apply to all forms or conditions of blood-borne pathogen exposure. Users of the test method must review modes for face exposure and assess the appropriateness of this test method for their specific application.  
1.3 This test method primarily addresses the performance of materials or certain material constructions used in medical face masks. This test method does not address the performance of the medical face mask’s design, construction, or interfaces or other factors with the potential to affect the overall protection offered by the medical face mask and its operation (such as filtration efficiency and pressure drop). Procedures for measuring these properties are contained in Test Method F2101 and MIL-M-36954C.  
1.4 This test method does not address breathability of the medical face mask materials or any other properties affecting the ease of breathing through the medical face mask. This test method evaluates medical face masks as an item of protective clothing. This test method does not evaluate the performance of medical face masks for airborne exposure pathways or in the prevention of the penetration of aerosolized body fluids deposited on the medical face mask.  
1.5 The values stated in SI units or inch-pound units are to be regarded separately as standard. The pressure values stated in each system are not exact equivalents. However, as the corresponding velocities are within 1 % of each other, (see X1.4.2), reporting of the results in either units is permitted.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of ...

ASTM F3163-22(Guide)
Standard Guide for Categories and Terminology of Cellular and/or Tissue-Based Products (CTPs) for Skin Wounds

SIGNIFICANCE AND USE
4.1 This guide provides definitions and a classification for CTPs, as well as definitions related to skin tissue, skin wounds and ulcers, wound healing physiology, wound covers, and related medical and surgical procedures. This guide is not intended to prescribe or limit the clinical uses of these products.  
4.2 One objective of the current guide is to include the wide range of CTPs for which there is a rationale for benefit beyond that achievable with conventional wound coverings. Whether an individual CTP is capable of promoting wound healing must be determined by adequate evidence and is beyond the scope of this standard. Given that some of the materials used in dressings and skin substitutes (defined in Guide F2311) are the same as those used in CTPs, there has been confusion as to how to classify these products.  
4.3 This guide is distinguished from Guide F2311, which defines terminology and provides classification by clinical use for products that can be substituted for tissue grafts of human or animal tissue in medical and surgical therapies of skin lesions. In contrast, this guide defines terminology for description of CTPs for skin wounds; CTPs are defined primarily by their composition. Neither guide establishes a correspondence between device structure and clinical function.
SCOPE
1.1 This guide defines terminology for description of cellular and/or tissue-based products (CTPs) for skin wounds. CTPs are TEMPs (tissue-engineered medical products) that are primarily defined by their composition and comprise viable and/or nonviable human or animal cells, viable and/or nonviable tissues, and may include extracellular matrix components. CTPs may additionally include synthetic components.  
1.2 This guide also describes categories and terminology for CTPs based on their composition. This systematic categorization is not intended to be prescriptive for product labeling, and it describes only the most salient characteristics of these products; the actual biological and clinical functions can depend on characteristics not recognized in the categorization and it should be understood that two products that can be described identically by the categorization should not be presumed to be identical or have the same clinical utility.  
1.3 This guide defines CTP-related terminology in the context of skin wounds. However, this guide does not provide a correspondence between the CTP composition and its clinical use(s). More than one product may be suitable for each clinical use, and one product may have more than one clinical use.  
1.4 This guide does not purport to address safety concerns with the use of CTPs. It is the responsibility of the user of this standard to establish appropriate safety and health practices involved in the development of said products in accordance with applicable regulatory guidance documents and in implementing this guide to evaluate the cellular and/or tissue-based products for wounds.  
1.5 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.  
1.6 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.

Standard Test Method for Sensory Evaluation of Oleoresin Capsicum

SIGNIFICANCE AND USE
5.1 This test method provides quick and accurate ratings for the sensory heat in oleoresin capsicums ranging from 100 000 to 1 000 000 Scoville heat units.  
5.2 Sensory results from this test method correlate highly (r2 = 0.94) with results from high pressure liquid chromatography; making the two methods substitutable.6
SCOPE
1.1 This test method describes standardized procedures for the sensory evaluation of heat in oleoresin capsicums ranging from 100 000 to 1 000 000 Scoville heat units (S.H.U.).  
1.2 This test method is intended as an alternative to the Scoville heat test, but results can be expressed in Scoville heat units (see ASTA Method 21.0 and ISO 3513).  
1.3 This test method does not apply for ground red pepper, low heat chili peppers, or chili powder.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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 F2458-05(2015)(Test Method)
Standard Test Method for Wound Closure Strength of Tissue Adhesives and Sealants

SIGNIFICANCE AND USE
4.1 Materials and devices that function at least in part by adhering to living tissues are finding increasing use in surgical procedures either as adjuncts to sutures and staples, or as frank replacements for those devices in a wide variety of medical procedures. While the nature and magnitude of the forces involved varies greatly with indication and with patient specific circumstances, all uses involve to some extent the ability of the material to resist imposed mechanical forces. Therefore, the mechanical properties of the materials, and in particular the adhesive properties, are important parameters in evaluating their fitness for use. In addition, the mechanical properties of a given adhesive composition can provide a useful means of determining product consistency for quality control or as a means for determining the effects of various surface treatments on the substrate prior to use of the device.  
4.2 The complexity and variety of individual applications for tissue adhesive devices, even within a single indicated use (surgical procedure, which itself may vary depending on physical site and clinical intention) is such that the results of a single tensile strength test is not suitable for determining allowable design stresses without thorough analysis and understanding of the application, adhesive behaviors, and clinical indications.  
4.3 This test method may be used for comparing adhesives or bonding processes for susceptibility to fatigue, mode of failure, and environmental changes, but such comparisons must be made with great caution since different adhesives may respond differently to varying conditions.  
4.4 A correlation of the test method results with actual adhesive performance in live human tissue has not been established.
SCOPE
1.1 This test method covers a means for comparison of wound closure strength of tissue adhesives used to help secure the apposition of soft tissue. With the appropriate choice of substrate, it may also be used for purposes of quality control in the manufacture of medical devices used as tissue adhesives.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.
