ASTM D4009-92(2023)(Guide)
Standard Guide for Foam Stability of Hand Dishwashing Detergents

SIGNIFICANCE AND USE
3.1 The guide, as now constituted, is not suitable for ranking of hand dishwashing products, since no basis is available at this time for correlation of the foam stability of these products using any particular food soil or combination of soils with consumers' ranking of performance.  
3.2 The relative foam stability ranking of hand dishwashing detergent products will vary greatly depending on the type of food soils used in the test. Therefore, selection of the standard food soil to be used in a test shall be made by agreement between the interested parties on the basis of experience.  
3.3 This laboratory screening guide includes flexibility in several areas so as to allow its use by the maximum number of laboratories, without purchase of significant additional equipment. It should be recognized, therefore, that differences in specific equipment may result in a reduced level of interlaboratory and inter-operator precision, and such results must be evaluated with caution.
SCOPE
1.1 This guide provides guidelines for several techniques of measuring the foam stability of light-duty hand dishwashing detergent products in the presence of artificially applied test-food soils. It is intended as a laboratory screening test to aid in the formulation of products, for quality control and as a basis between the formulator and supplier in standardizing foam stability of the detergents.  
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Foaming Properties of Surface-Active Agents

ABSTRACT
This test method covers the determination of foaming properties of surface-active agents. Glass tubing apparatus for this test method shall include pipet and a receiver. Apparatus requirements like dimensions, shape, calibration marks, rubber stoppers, etc., shall conform to the specifications as indicated in this standard method. Test solution preparation shall include water preheating, adding the surface-active agent while stirring, and solution aging. Test procedure for foaming properties determination shall be done while surface-active solution is aging as indicated in this standard test method. Report shall include test solution concentration, temperature, water hardness, and foam height.
SCOPE
1.1 This test method covers the determination of the foaming properties of surface-active agents as defined in Terminology D459. This test method is applicable under limited and controlled conditions, but does not necessarily yield information correlating with specific end uses. This method is subjected to the operator of the method as the foam heights are not always level and an average height is determined by the user so it is more of a qualitative measurement in these instances. However, for foam measurements results taken on more flat uniform samples this method has more of a quantitative quality.  
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.

Standard Test Method for Cloud Point of Nonionic Surfactants

SIGNIFICANCE AND USE
3.1 The cloud point temperature is a reproducible characteristic of certain  pure  nonionic surfactants. It is also characteristic of certain nonionic surfactant formulated systems. This test method is appropriate for both systems.
Note 1: If the transition from a distinctly cloudy to a clear solution is not sharp, that is, if it does not take place within a range of 1 °C, this test method is not appropriate.
SCOPE
1.1 This test method covers a procedure to determine the “cloud point” of nonionic surfactants or detergent systems. Cloud Point is the temperature at which dissolved components (solids or liquids) are no longer completely soluble, precipating as a second phase giving the fluid a cloudy appearance. It is limited to those surfactants and detergent systems for which the visible solubility change occurs over a range of 1 °C or less at concentrations of 0.5 % to 1.0 % in DI water between 30 °C and 95 °C.  
1.2 Chemical Limitations—Nonionic surfactants that exhibit a characteristic cloud point in general terms consist of a water-in-soluble moiety condensed with 50 % to 75 % by weight of ethylene oxide. If the level of ethoxylation is too low the surfactant may not be water soluble at temperatures less than 30 °C, and if it is too high no cloud point may exist.  
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.

Standard Guide for Maintenance of Marine Sanitation Devices (MSDs) and the Effects of Cleaning Agents on MSD Operations

SCOPE
1.1 The guide provides information and clarity to support the health and maintenance of Marine Sanitation Devices (MSDs) on maritime vessels and platforms to promote effective operations and performance throughout the lifecycle. This includes identification of chemicals and their derivatives that can be detrimental to proper MSD operations. This guide will promote better understanding of the impacts of certain chemicals on the health and operations of MSD systems, plus provide guidance to inform operators of best practices and procedures for effective operations and maintenance. This guide is designed to assist both operators and MSD Original Equipment Manufacturers (OEMs) in collaboratively working to ensure effective operations and maintenance, and to reduce performance degradations that result from the introduction of harmful chemicals. The primary application of this guide is to Type II MSDs (described in Section 4), installed on larger ships and employing biological treatment of sewage and gray water.
Note 1: This guide does not constitute regulations or ship classification society rules, which should be consulted where applicable.  
1.2 Manufacturers preparing new product specifications or revising existing ones should follow the practices and procedures outlined herein, and be guided by the latest specifications covering similar commodities. Similarly, vessel owner/operators should consult this guide regarding in-service operations and maintenance.  
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.
