4.1 This test method will provide an indication of the effectiveness of the cleaning system at restoring the appearance of an artificially soiled carpet by wet extraction cleaning. The cleaning effectiveness in the laboratory test may not be the same as in home cleaning due to variations in the homes, carpets, soils, and other factors.4.2 In order to provide a uniform basis for measuring the performance described in 1.1, standardized test carpet, test pad, and test soil are employed in this procedure.1.1 This test method provides only a laboratory test for visually determining the relative carpet cleaning effectiveness of a wet extraction cleaning system when tested under standard conditions.1.2 This test method is applicable to types of upright, canister, and combination wet extraction cleaners and their recommended chemical cleaning formulas intended for cleaning carpets as a primary or secondary function. This test method excludes pre-spray systems or pre-spray treatments.1.3 This test method is not applicable to upholstery cleaning or bare floor cleaning.1.4 This test method applies only to the cleaning of embedded soil from carpet, not the removal of surface litter and debris.1.5 This test method does not directly quantify the amount of soil removed but is visually assessed by employing colorimetric instrumentation.1.6 Units—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. 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 Cleaning provides well documented benefits in terms of creating cleaner, safer, and healthier surroundings by extracting harmful pollutants from the indoor environment (see Ref (3)). An improperly maintained indoor environment could give rise to biological contaminants, and buildup of particulate matter and gases which can have serious health effects. These negative impacts may have adverse affects on worker productivity affecting both cleaning personnel and tenants through increased complaints, absenteeism, injuries, asthmatic incidents, or other symptoms. Inappropriate or improper use or selection of cleaning products and processes, along with failure to follow label directions could result in injury or illness to cleaning personnel or building occupants. In addition, it may be detrimental to the physical structure and systems of the building, or to the environment. Moreover, owners and operators maintain the liability for the proper function of the building and its impacts on the occupants and cleaning personnel.4.1.1 This guide provides a basic reference for the development and preservation of a building environment that is considered safe and healthy for occupants, while reducing the stress on the overall environment as a result of routine maintenance. The anticipated users of this guide include building managers, cleaning personnel, product suppliers and distributors, union representatives, and building occupants who serve together in a stewardship role regarding the maintenance of the building. This guide is intended to raise pertinent questions regarding specific building environments in order that an appropriate stewardship strategy may be developed, for example:4.1.1.1 How is the building used?4.1.1.2 Are there any special cleaning requirements?4.1.1.3 Are there any at-risk populations that need to be considered, such as children, asthmatics, or pregnant woman?4.1.1.4 How are cleaning materials used?4.1.1.5 Are there any special issues relevant to construction and furnishings?4.1.1.6 Are there any issues relating to building age/architectural, such as historic preservation requirements?4.1.1.7 are there any engineering concerns, such as HVAC systems and natural ventilation?4.1.1.8 How is the quality of cleaning being evaluated or measured?4.1.2 Regardless of the specific requirements, this guide will help in the formulation of a comprehensive plan resulting in reduced risk to cleaning personnel, building occupants, and the environment.4.2 This guide will help the building owner and operator understand the cleaning process through the following:4.2.1 The development of a stewardship plan (see Section 6), will clarify the level of cleanliness that is required or expected, and will ensure that the cleaning process is carried out in a consistent manner with adequate communication feedback to promote success of the plan.4.2.2 An understanding of extended product responsibility (see Section 7) and the importance of shared responsibility. This section includes task identification and performance requirements, process and product selection, use, storage, and disposal.4.2.3 An identification of the training and communications issues (see Section 8) that will encourage involvement with the entire chain-of-commerce in the cleaning process. These issues are related to both procedural training and feedback opportunities for cleaning personnel, as well as information sharing with building tenants to inform them of possible cleaning process impacts.1.1 This guide covers a procedure to assist owners and operators of commercial and institutional buildings in the stewardship of cleaning and housekeeping operations. The focus of this guide is to address appropriate cleaning activities and processes, to promote eco-efficiency and sustainability, and to avoid adverse impacts on the building occupants, cleaning personnel, the building structure itself, and the environment. Adherence to the principles set forth in this guide can lead to greater tenant/occupant satisfaction, reduced operational costs and greater productivity (of occupants and cleaning personnel).1.2 This guide will focus on the development of a stewardship plan and will include the assessment of cleaning processes, product selection, storage, usage, disposal, equipment, training of cleaning personnel and communication throughout the chain-of-commerce.1.3 This guide addresses issues relating to the operation and maintenance of the heating, ventilating and air conditioning (HVAC) systems which can have a major impact on indoor air quality (IAQ) only to the extent that the HVAC system provides adequate ventilation to lower risk to cleaning personnel, building occupants and the environment during or as a result of the cleaning process.1.4 This guide is for use in a building that is maintained by either in-house cleaning personnel or an outside cleaning contractor.1.5 This guide is not intended for construction related activities, but may be appropriate for post construction clean-up.1.6 This guide is not intended as a procedural guide for cleaning personnel.1.7 This guide is not intended for use in residential buildings.1.8 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.9 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.1.10 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.1.11 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 Hydraulic cleaning methods include equipment that uses water and water velocity to clean the invert and walls of the vitrified clay sewer pipe.4.2 The practice of high-velocity sewer cleaning is best described as a hydraulic cleaning method that uses water pressure to remove obstructions and deposits in sewers or storm drains.4.3 There are different configurations of high-velocity sewer cleaning machines. These units have the capability of generating variable water pressures up to 3500 psi (24 MPa) and variable flow rates of 50-125 gal per min (gpm) (180-473 L per min).4.4 The water tank capacity on these units varies from 1000-1500 gal (3785-5678 L).4.5 The hose lengths vary between 500 and 1000 ft (152 and 305 m) in length with a diameter of 3/4- 11/4 in. NPT.4.6 There are number of different nozzles and tools that may be used during the cleaning process.4.7 Some high-velocity sewer cleaners have a vacuum conveyance system that use large fans or positive displacement vacuum pumps for material removal capabilities. With this type of system, material can be vacuumed from the manhole into a debris tank as it is brought back with the jet or tool and taken to a disposal area. These systems can be either trailer or truck mounted and are generally known as combination machines.4.8 The Occupational Safety and Health Administration (OSHA) has set guidelines for the safe removal of hazardous and nonhazardous substances as stated in OSHA Section 5 of Public Law 91-596; OSHA 29 USC 654; 29 CFR 1910.120; as well as DOT CFR Parts 106-7, 171-180, and 390-397.1.1 This practice covers the personnel requirements, operator training, operating procedures, and recommended equipment performance/design for the proper operation of pressure water-jet cleaning and cutting equipment as normally used by municipalities and contractors tasked with operations, maintenance, cleaning, and pre-rehabilitation cleaning work of vitrified clay mainline sewer pipe.1.2 The term “high-pressure water jetting” covers all water jetting, including the use of jets and hydromechanical tooling at pressures above 2000 psig (0.69 MPa).1.3 This practice covers the “high-pressure water jetting” of vitrified clay pipe and should not be applied to other pipe and pipe lining materials without evaluating the recommended cleaning procedure from the manufacturer to avoid damage.1.4 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, 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.
