(G) Test Methods 

(1) A violation of the limits contained in this rule as determined by any one of these 

test methods shall constitute a violation of this rule. 

(2) The following specified test methods shall be used to determine compliance with 

the provisions of this rule. 

(a) VOC Determination 

(i) Samples of Automotive Coatings as specified in subsection 

(C)(1)) shall be analyzed as prescribed by EPA Reference Method 

24, as set forth in appendix A of Title 40 of the Code of Federal 

Regulations (40 CFR) Part 60, “Determination of Volatile Matter 

Content, Water Content, Density , Volume Solids, and Weight 

Solids of Surface Coatings” for VOC content (without correction 

for Exempt Compounds) and the American Society for Testing 

Materials (ASTM) Test Method D4457-85, 91(Standard Test 

Method for Volatile Content of Coatings), or ARB Method 432 

(“Determination of Dichloromethane and 1,1,1 – Trichloroethane 

in Paints and Coatings”, 1989) for determination of emissions of 

Exempt Compounds. Perfluorocarbon compounds shall be 

assumed to be absent from a product or process unless a 

manufacturer or facility operator identifies the specific individual 

compounds (from the broad classes of perfluorocarbon 

compounds) and the amounts present in the product or process and 

provides a validated test method which can be used to quantify the 

specific compounds. 

(b) Determination of Emissions-Operations with Emission Control Systems 

(i) For operations with Emission Control Systems, VOC emissions as 

specified in subsection (C)(3)(a) shall be measured as prescribed 

by EPA Reference Method 25, 25A, or 25B, Title 40 Code of 

Federal Regulations, Part 60, Appendix A, for determining VOC 

emissions and control device efficiency , in combination with the 

methods prescribed in U.S. EPA’s “Guidelines for Determining 

Capture Efficiency.” (January 9 1995) and Title 40 Code of 
1116-16 MDAQMD Rule 1116 

Automotive Refinishing Operations 

D3: 08/23/10 

Federal Regulations, Part 51, Appendix M, Methods 204-204f, as 

applicable, for determination of capture efficiency.

(c) Determination of HVLP Transfer Efficiency Equivalence 

(i) Transfer Efficiency equivalent to HVLP as required by subsection 

(C)(6)(a)(iii) shall be determined by procedures as prescribed in 

the South Coast Air Quality Management District (SCAQMD) 

document "Guidelines for Demonstrating Equivalency with 

District Approved Transfer Efficient Spray Guns, September 26, 

2002". 

(d) Determination of Transfer Efficiency 

(i) Transfer Efficiency as required by subsection (C)(6)(a)(iii) shall be 

determined by procedures as prescribed in the SCAQMD 

document "South Coast Air Quality management District Spray 

Equipment Transfer Efficiency Test Procedure for Equipment 

User, May 24, 1989". 

(e) Determination of Percentage of Metal in Metallic/Iridescent Color 

Coatings 

(i) Determinations shall be made using SCAQMD Method 311, 

“Determination of Percent Metal in Metallic Coatings by 

Spectrographic Method”, as found in the SCAQMD document 

Laboratory Methods Of Analysis For Enforcement Samples
