          VI.   Test Methods

                A.  Analysis of Samples- Samples of VOC as specified in 
                    this Rule shall be analyzed by U.S. EPA Method 24 and
                    analysis of halogenated exempt compounds shall be
                    conducted using CARB Method 432 or ASTM D4457-85 and be
                    consistent with provisions set forth in the Federal
                    Register (FR. Vol. 56, No. 52, March 18, 1991).

                B.  Determination of Emissions - Emissions of VOC shall be
                    measured by U.S. EPA Method 25, 25A, or 25B, as
                    applicable.

                C.  Determination of Capture Efficiency - Where add-on
                    control equipment is utilized, capture efficiency 
                    shall be determined in accordance with 40 CFR 52.741.

                D.  Quantification of Metallic/Iridescent Topcoat -
                    Quantification of coating as a metallic/iridescent
                    topcoat shall be determined by South Coast Air Quality
                    Management District "Test Method 311-91", "Analysis of
                    percent Metals in Metallic Coatings by Spectrographic
                    Method."

                E.  Measurement of Acid Content - Acid content of Pre-
                    Treatment Wash Primers shall be conducted and reported
                    in accordance with ASTM D1613-85 Standard Test Method
                    for Acidity in Volatile Solvents and Chemical
                    Intermediates used in Paint, Varnish, Lacquer, and
                    Related Products.

                F.  Demonstration of Transfer Efficiency - Transfer
                    efficiency shall be demonstrated using South Coast Air
                    Quality Management District Method "Spray Equipment
                    Transfer Efficiency Test Procedure for Equipment User."

                G.  Determination of VOC Composite Partial Pressures - VOC
                    composite partial pressures shall be determined using
                    either manufacturer's information regarding formulation
                    or using ASTM Methods E168-92, E169-93, or E260-91 for
                    determination of mole fractions and then summing
                    products of each VOC component's vapor pressure and its
                    mole fraction.  For materials containing no non-VOC
                    components, VOC composite partial pressure can be
                    measured directly by ASTM Method D2879-86.

                H.  Determination of VOC Emissions From Spray Gun Cleaning
                    Systems-VOC emissions shall be determined using
                    South Coast Air Quality Management district "General
                    Test Method for Determining Solvent Losses from Spray
                    Gun Cleaning Systems".
