Tile and Plank Products - If standard manufacturer packaging materials are not used a minimum of four representative tiles, strips or planks, each with a minimum surface area of at least 64 square inches, shall be collected. The tiles, strips or planks shall be stacked tightly together face to back and immediately placed in specialized packaging.
Sheet and Roll Goods - Goods shall be cut at a minimum width of 12" across the entire width of the roll. Following cutting, the product shall be tightly rolled and immediately placed in specialized packaging. Wallcovering and other fabric may be collected as a full or partial production roll. In these cases, the roll shall have at least 10 layers of material and may be provided collected from the packaging line or placed in specialized packaging.
Rigid Panel Products - For large panel products, the entire panel may be shipped as long as the sample is appropriately sealed. As an alternative, smaller samples may be collected from the larger panel. These samples shall be collected at least 6 inches away from all edges of the larger panel, the smaller panel samples shall be cut into approximate 12" x 12" squares. A minimum of four squares is required. The squares shall be stacked tightly together face to back and immediately placed in specialized packaging.
Insulation - In order to best represent the finished product, air that may be exchanged in, and evacuated from, the packaging process should be simulated as much as possible. The cooling of the product is also a factor when the collection point is established.
 Batts and Rolls: Most, if not all of these materials are packaged in bags as an integral point of manufacturing. Further, air is generally evacuated from the package to reduce the physical size of the packaged product for shipping purposes. The product should be removed from its original packaging and placed into the specialized packaging. Manufacturers who wish to continue to collect samples directly from the production line may continue to forego packaging and may establish an earlier point of sample collection as long as the sample is cool. Samples shall be submitted per the following size requirements: 18" x 30", samples of the same material may be cut into smaller sizes (no smaller than 12" x 12") and placed in the same packaging.
 Boards and Rigid Foam Products: As board products are generally boxed, opening the final package would be both difficult and cause excessive waste. In this case, the sample should be removed immediately from the production line and allowed to condition for 15 minutes (± 2 minutes) under standard laboratory conditions in the plant prior to packaging for emissions testing. Manufacturers who provide GREENGUARD Certified products for furniture panel applications will be expected to deliver product for the purposes of emissions testing in the same fashion as standard board products. Manufacturers who wish to continue to collect samples directly from the production line may continue to forego packaging and may establish an earlier point of sample collection. Samples shall be submitted per the following size requirements: 18" x 30", samples of the same material may be cut into smaller sizes (no smaller than 12" x 12") and placed in the same Mylar packaging bag.
 Blowing Wools and Loose Fill Products: It has been determined that the collection of loose fills or blowing wools is not easily achieved directly from the production line, dependent on the manufacturer. The sample collection procedure shall be consistent with Batts and Rolls. Sample collection, in this case, requires collection of product from the compressed or evacuated product package, 15 minutes (± 2 minutes) following packaging. Manufacturers who wish to continue to collect samples directly from the production line may continue to forego packaging and may establish an earlier point of sample collection. Samples shall be submitted per the following size requirements: Loose fill insulation shall be placed in a specialized packaging bag, filling roughly 66% to 75% of the bag.
 Spray Foam Insulation: As these products do not come off a manufacturing line, the following collection processes have been instituted to most closely mimic those associated with spray foam installation.
o Closed Cell Foam Insulation: Spray a 12" x 12" sample to thickness (based on stud size) – 1 or 2 passes 1.5"- 2" thick. Wait 1 hour (or shortest time allowed before able to be cut). Place in Mylar bag
o Open Cell Foam Insulation: Spray a 12" x 12" sample to thickness – 3.5"- 4" for walls, 6" for attics. Scarf the sample (usually done within 15 minutes of spraying to remove excess foam). Wait 24 hours. Place in Mylar bag.
Containerized and Wet Products - Products can be supplied in original, standard 1-quart or 1-gallon consumer containers. Adhesives can be supplied in their consumer packaging such as an applicator tube or can (if less than 1 gallon). Alternatively, adhesive and paint samples can be collected in clean, unused paint cans (1-pint or 1-quart size). Special care is required to assure that these samples are representative of the larger batches from which they are collected. Containers shall be filled so there is minimal unfilled headspace above or below the adhesive. Samples of containerized products sent to a laboratory shall also be accompanied by a Material Safety Data Sheet (MSDS) and a specification sheet that describe
