EAIs may have design features such as coiled metal sheaths, pivoting joints, opposed surfaces, and internal lumens or wires which make visual inspection for cleanliness difficult if not impossible.By nature of their design requirements, EAIs are more difficult to reprocess than many other types of medical instruments.Because EAIs are used to diagnose and treat disease in both immunocompetent and immunocompromised individuals, care must be taken to ensure that only patient-ready devices are used for examination.The use of EAIs in patients having diagnosed or suspected infections such as hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) is not contraindicated. Further, EAIs need not be dedicated for use only in these patients.Persons responsible for reprocessing must understand the specifications, nomenclature, function of component parts, and interior design of EAIs in order to render them patient-ready.Persons responsible for reprocessing EAIs should follow this practice and associated labeling and instructions from manufacturers after each endoscopic procedure to ensure that the EAI will be patient-ready.Reprocessing of EAIs should be the specific responsibility of appropriately trained personnel. Temporary employees without the requisite training should not be given these responsibilities.The responsibility for reprocessing of EAIs should not be delegated from person to person unless each has the appropriate training for the position.Reprocessing personnel should have the ability to read, understand, and implement instructions from manufacturers and regulatory agencies as they relate to EAI reprocessing.Reprocessing personnel should have the opportunity to become completely familiar with the mechanical aspects of the devices. They may gain this knowledge through study of the manufacturer's information and demonstration by representatives.Reprocessing personnel should be made fully aware of the potential chemical and infectious hazards for patients and health care personnel associated with the reprocessing of EAIs. Training should include:A thorough background in infection control principles and concepts based on written in-house infection control procedures.A thorough background regarding the potential for negative patient outcomes resulting from lapses in compliance with written reprocessing guidelines,Familiarization with Occupational Safety and Health Administration (OSHA) regulations and in-house policies regarding the appropriate and safe handling of chemical reprocessing agents and equipment used during reprocessing of EAIs, andInformation on the safe handling of EAIs contaminated with patient tissue and fluids after use, including familiarization with principles and practices of standard (universal) precautions.Note 1—Although healthcare workers and patients may benefit from adhering to the regulatory guidelines issued by federal and state OSHA agencies, these guidelines are directed only toward healthcare worker safety and health. They may not be sufficiently inclusive for optimum safety and health of patients. Therefore, contemporary infection control guidelines should be consulted in addition to OSHA guidelines.This practice is not intended to replace the reprocessing instruction provided by the manufacturers of EAIs or suggest specific equipment or chemical reagents to be used for reprocessing. Rather, it is to be used together with manufacturers' instructions that provide specific instructions for specific products. See Appendix X1.1.This practice is not intended to cover endoscopic techniques, patient care, or other medical aspects of flexible endoscopy.This practice does not include instruction for reprocessing flexible endoscopes.1.1 This practice covers reusable, heat-stable endoscopic accessory instruments (EAI) designed to be inserted into flexible endoscopes and clearly defined in the user instructions as devices intended for reuse among patients. The EAIs covered by this practice may or may not have lumens or loosely joined surfaces, may or may not have access ports for flushing, and may or may not be capable of being completely disassembled prior to reprocessing.1.2 This practice is not intended to be applied to the reprocessing of single-use, disposable EAIs specifically designed and labeled as such by their manufacturers.1.3 This practice is not intended to address reprocessing of heat-sensitive EAIs, for example, those not capable of withstanding heat sterilization. Reprocessing of each heat-sensitive EAI must be considered on an individual basis according to specific instructions from the manufacturers of the EAI and the low-temperature sterilization device.1.4 This practice is intended to complement, not replace, the instructions provided by product manufacturers. EAI manufacturers should provide properly validated instruction and labeling necessary for users to understand the basic design, specifications, nomenclature, and components of specific accessories and to properly inspect, prepare, use, reprocess, and store these instruments.1.5 Endoscopic technique and the medical aspects of endoscopy are not covered in this practice.1.6 This practice details the basic steps necessary to reprocess a heat-stable EAI and render it patient-ready.1.7 A patient-ready EAI is one that has been thoroughly cleaned using a validated cleaning procedure, rinsed with water to remove residual detergent, lubricated (if necessary) and drained to remove excess lubricant, dried, packaged, heat sterilized and stored to prevent from being compromised sterility before use.1.8 This practice describes only manual reprocessing and does not address cleaning of an EAI by an automated reprocessing device.1.9 To ensure the proper adherence to this practice, reprocessing personnel should meet certain requirements as specified in 5.5 to 5.7.1.10 This practice does not address the steps necessary for the reprocessing of flexible endoscopes (see Practice F 1518).1.11 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 to determine the applicability of regulatory limitations prior to use.

5.1 A critical step in preparing a medical device for safe use on the next patient is effective cleaning. Typically cleaning a medical device includes precleaning at the point-of-use, manual and automated methods for removing soil that accumulate during clinical use. The cleaning solution(s) used are almost always water for rinsing and water with a detergent during washing. AAMI TIR34 (also EN 285) provides guidance about the quality of water to be used during reprocessing. This guidance references various test methods to ensure that water meets the recommended quality.5.2 When it comes to detergents very little guidance can be found in AAMI, ISO, ASTM, and FDA documents. Further, there are very few consensus methods for evaluating the detergents intended to clean medical devices. The result is that very little detail about detergents, for comparison purposes, is known. As a result, device manufacturers, when authoring their instructions for use (IFU) describe in very generic terms the kind of detergent that can be used to clean their device. Similarly, regulators, also have very little to rely upon for clearing reprocessing instructions. Finally, the healthcare facility, that is ultimately responsible for getting the device clean, has very little detail to assure that one brand of detergent is roughly equivalent to the one used by the medical device manufacturer during validation testing.5.3 While consensus standard test methods do not exist for detergents intended to clean medical devices, there are dozens of such test methods when it comes to detergents intended to clean dishes, laundry, floors, countertops, and so forth. Many of these methods are under the domain of ASTM D12: Soaps and other Cleaning Agents Including Detergents. While differences certainly do exist, essentially the detergents used for the other purposes are roughly formulated in the same way. Using existing test methods can drive detergent formulation development or determine the need for new test methods for medical device cleaning, where or if needed.1.1 Detergents play a critical role in the cleaning of clinically-used medical devices, but there are few consensus methods for describing the key characteristics of these detergents. This guide identifies consensus standards, ASTM and others, used to characterize detergents in other applications, which can also be used to characterize detergents used to clean clinically-used medical devices.1.2 In identifying these test methods, manufacturers of detergents can reference this guide to characterize their detergents.1.3 By identifying applicable test methods, gaps may be identified where development of new standardized test methods need to be developed to characterize detergents intended to clean medical devices.1.4 By identifying applicable test methods that are used and results reported by detergent manufacturers, test results can be shared and may lead in the future to development of performance criteria for the key characteristics of detergent.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 Exclusions: 1.6.1 This guide is not intended for detergents formulated to remove residues as a result of the manufacturing process.1.6.2 This guide does not provide information related to disinfection or disinfecting agents that might be part of a detergent formulation.1.7 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.1.8 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.

4.1 This practice provides uniform guidance for cleaning the laboratory glassware, plasticware, and equipment used in routine microbiological analyses. However, tests that are extremely sensitive to toxic agents (such as virus assays) may require more stringent cleaning practices.21.1 In microbiology, clean glassware is crucial to ensure valid results. Previously used or new glassware must be thoroughly cleaned. Laboratory ware and equipment that are not chemically clean are responsible for considerable losses in personnel time and supplies in many laboratories. These losses may occur as down time when experiments clearly have been adversely affected and as invalid data that are often attributed to experimental error. Chemical contaminants that adversely affect experimental results are not always easily detected. This practice describes the procedures for producing chemically clean glassware.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.

5.1 It is important to evaluate the corrosion resistance of ferrous metal components used in low-slope roofing and waterproofing because they provide integrity and securement of other system components, such as insulation and membranes. Corrosion of ferrous metal components may result in their early deterioration and may lead to roofing or waterproofing system failure.5.2 Results from testing ferrous metal components in an acidic atmosphere serve as an indication of the relative corrosion resistance of such components, coated or uncoated, to the environment of the test chamber. The results are not to be construed as a general guideline to the corrosion resistance of such components in other environments or in usage that may be conducive to corrosion.5.3 Moist air containing sulfur dioxide quickly produces easily visible corrosion on many ferrous metals. It is therefore a test medium suited to detect pores or other sources of weakness in protective barrier coatings.5.4 This test method applies primarily to evaluating the effectiveness of barrier coatings to provide general corrosion protection under test conditions. It is not intended to evaluate the resistance of the components to specific corrosion mechanisms such as crevice, galvanic, or stress corrosion.5.5 This test method does not address abrasion resistance of barrier coatings when the fasteners are driven through above roof deck components, such as an existing built-up roof or insulations, or both.5.6 Only the above deck portion of fasteners subjected to this test method is evaluated.1.1 This test method covers components of ferrous metal fastener assemblies, excluding those of stainless steel, such as fasteners, stress plates, and batten bars used in low slope roofing and waterproofing, to a sulfurous acid environment. This test method evaluates relative corrosion resistance of the components by determination of percentage of rust or white rust.1.2 The components may or may not have a surface treatment applied.1.3 A limiting factor is the subjectiveness when determining actual percentage of rust or white rust corrosion.1.4 Other performance characteristics of ferrous metal components such as abrasion resistance of barrier coatings are not evaluated in this method.1.5 This test method was developed based on Practice G87.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 These test methods provide a field technique for the bacteriological analysis of electronic process waters. The sampling of these waters and subsequent bacteriological analysis may be critical to electronic product yields. Bacteria can be the prime source of harmful contamination which can significantly reduce the yield of satisfactory microelectronic device production.5.2 The test methods described here may be used both to monitor the bacteriological quality of water used in microelectronic product processing, and to locate the source of bacterial contamination in a water purification system.5.3 These test methods are simple field methods, combining sampling and bacteriological analysis techniques that do not require bacteriological laboratory facilities.5.4 The test methods described employ culture techniques for bacteriological analysis. The user should be aware that such techniques cannot provide a complete count of the total viable bacteria present, since clumps and clusters of bacteria will appear as one single colony when cultured, and since some viable bacteria will not grow under the test conditions used. However, a meaningful comparative bacteria count will be achieved by this method if the culturing of the sample is always done at the same temperature, and for the same period of time. The temperature of incubation should always be at 28 ± 2°C, and the period of incubation should be 48 h (or 72 h if time permits). The period of incubation and temperature should be the same for all comparative studies.1.1 These test methods cover sampling and analysis of high purity water from water purification systems and water transmission systems by the direct sampling tap and filtration of the sample collected in the bag. These test methods cover both the sampling of water lines and the subsequent microbiological analysis of the sample by the culture technique. The microorganisms recovered from the water samples and counted on the filters include both aerobes and facultative anaerobes.1.2 Three methods are described as follows:  SectionsTest Method A—Sample Tap—Direct Filtration 6 to 8Test Method B—Presterilized Plastic Bag Technique 9 to 12Test Method B2 —Dip Strip Technique2/Presterilized Plastic Bag  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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.
