V T E C L a b o r a t o r i e s I n c . April 12, 2023 Client: Formlabs 35 Medford Street Somerville, MA 02143 I. SCOPE: This report contains the reference to the test method, purpose, limitations, description of materials, operating data, and test results. II. TEST METHOD: The test was conducted in accordance with ASTM Designation E-662, "Standard Test Method for Specific Optical Density of Smoke Generated by Solid Material". III. PURPOSE: The purpose of the test is to measure the smoke generated by solid materials and assemblies in thickness up to and including one inch. The test is based on the attenuation of a light beam by smoke accumulating within a closed chamber. Both non-flaming and flaming exposures are conducted. Results are expressed in terms of specific optical density, which is derived from measuring optical density (absorbance). IV. DISCLAIMER: This is a factual report of the results obtained from the laboratory tests of sample products. The results may be applied only to the products tested and should not be construed as applicable to other similar products of the manufacturer. The report is not a recommendation or a disapprobation by VTEC Laboratories Inc. of the material tested.
