UL 2822:2018-04 GREENGUARD Certification Program Method For Measuring And Evaluating Chemical Emissions From Cleaners And Cleaning Maintenance Systems Using Dynamic Environmental Chambers.
1.1 Cleaning products and systems may emit a variety of volatile chemicals into the indoor air space of a building. The following methodology measures total volatile organic compounds (TVOC), individual volatile organic compounds (IVOCs), formaldehyde and other aldehydeslevels from cleaning products, materials, and complete cleaning systems associated with routine cleaning using test conditions defined to simulate product use in realistic commercial office, educational. healthcare and/or residential settings. The level of total or individual volatile organic chemical emissions is determined by observing the TVQC. IVOC, or aldehydeconcentrations in a dynamic environmental chamber under specified test conditions. The observed chamber concentration is converted by a mathematical calculation to an emission rate, a product specific variable, and then modeled to obtain room concentration estimates. The quantity of VOCs in the environmental chamber air is determined by gas chromatography/mass spectrometry. The methodology is generally applicable to volatile organic compounds with boiling points from 6OC to 29OC emitting from individual products. Emissions of selected aldehydes are measured using reverse-phase high-performance liquid chromatography (HPLC) with UV detection. Specialized analysis of chamber air samples may be conducted for other specific target chemicals as required for a specific product/project requirement.
1 .2 This method may be used for certification solely by UL and its affiliated entities in the UL GREENGUARD certification program. Accordingly, only UL or its affiliated entities can determine and declare whether a product is in compliance with the requirements in this method. Any purported determination or declaration of testing, conformance, compliance or certification to this method by any other party is null and void and cannot be used to meet the requirements of this method.
1.3 The methodology provides a standard means of reproducibly and accurately testing cleaning products and systems under a realistic, yet highly controlled, atmosphere.
1.4 The methodology with standardized measurement and analyses provides consistent testing of products.
1.5 This protocol applies to any cleaning product or system belonging to a product category generally used within an enclosed indoor environment. This includes, for example, general cleaners, glass cleaners, toilet cleaners, floor cleaners, hard surface cleaners, institutional cleaning systems, aerosol products and carpet cleaners used in public and commercial office buildings, schools, medical buildings, residences and other building types. The protocol applies to products that can be tested alone or as part of a system.
1.6 This method establishes the procedures for product sample collection, emission testing and analysis, indoor air concentration modeling and associated documentation requirements.
1.7 This method also establishes performance criteria for specific chemicals of interest.
1.8 This method also establishes performance criteria for specific chemicals of interest.UL 2822 pdf download.
