Underwriter's Laboratories (UL). Underwriter's Laboratories Environment (UL Environment). UL 2824 – GREENGUARD Certification Program Method for Measuring Microbial Resistance From Various Sources Using Static Environmental Chambers. ASHRAE 189.1 – “Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings”. California Department of Public Health - "Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers". Formaldehyde emissions shall not exceed 16.5 mcg/cu. m or 13.5 ppb, whichever is less, except for insulation manufactured without formaldehyde. DEFINITIONS Thermal Conductivity (K value): Heat flow property of a homogeneous material; the lower the “k” the better the insulating value. Expressed in units of Btu-inch/hour per square foot per degree F. Underwriters Laboratories Environment (UL Environment): independent, third-party green claims validation, product assessment and certification. 1. Environmental Claim Validation (ECV): Independent third-party review to single attribute environmental claims. a. Formaldehyde Free: Independent third-party validation of claim that a product does not contain formaldehyde (or formaldehyde precursors) using a combination of auditing raw material input and testing of chemical emission from the product. b. Recycled Content: 1. Pre-Consumer - materials used or created from one manufacturing process which are collected as scrap and placed back into another manufacturing process rather than being placed in a landfill or incinerated. 2. Post-Consumer - materials such as bottled glass collected at curbside or other collection sites after consumer use. 2. GREENGUARD Certification: Health based emission testing criteria for chemicals; requiring total VOC emission levels for products. 3. GREENGUARD Gold: Emission testing criteria for chemicals requiring lower total VOC emission limit levels for products acceptable for use in environments such as schools and healthcare facilities. Complies with California’s Department of Public Health (CDPH) “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers”; Version 1.1 (2010), also known as California Section 01350 . 4. Environmental Product Declaration (EPD): Independently verified and registered document providing information about the life-cycle impact of products
