6.3 Test Methods

The test methods listed below shall be used to demo nstrate compliance with this rule. Alternate equivalent test methods may be used provi ded the test methods have been approved by the APCO and EPA.

6.3.1 Calculation of VOC Content: For the purpose of determining compliance

with the VOC content limits in the Table of Standar ds 1 or the Table of Standards 2, the VOC content of a coating shall be determined as defined in Section 3.77, 3.78, or 3.79 as appropriate. The VOC content of a tint

base shall be determined without colorant that is a dded after the tint base

is manufactured. If the manufacturer does not recom mend thinning, the VOC Content must be calculated for the product as s upplied. If the manufacturer recommends thinning, the VOC Content m ust be calculated including the maximum amount of thinning solvent re commended by the manufacturer. If the coating is a multi-component p roduct, the VOC content must be calculated as mixed or catalyzed. I f the coating contains silanes, siloxanes, or other ingredients that gener ate ethanol or other VOC during the curing process, the VOC content must include the VOCs emitted during curing.

6.3.2 VOC Content of Coatings: To determine the p hysical properties of a

coating in order to perform the calculations in Sec tion 3.77 and 3.79, the reference method for VOC content is EPA Method 24, except as provided in Sections 6.3.3 and 6.3.16. An alternat ive method to determine the VOC content of coatings is SCAQMD Met hod 304-91 (Revised February 1996). The exempt compounds cont ent shall be determined by SCAQMD Method 303-91 (Revised 1993), BAAQMD Method 43 (Revised 1996), or BAAQMD Method 41 (Revi sed 1995), as applicable. To determine the VOC content of a coat ing, the manufacturer may use EPA Method 24, or an alternati ve method as provided in Section 6.3.3, formulation data, or any other reasonable means for predicting that the coating has been form ulated as intended (e.g., quality assurance checks, recordkeeping). H owever, if there are any inconsistencies between the results of EPA Meth od 24 test and any other means for determining VOC content, the EPA Me thod 24 test results will govern, except when an alternative met hod is approved as specified in Section 6.3.3. The District Air Pollu tion Control Officer (APCO) may require the manufacturer to conduct an E PA Method 24 analysis.

6.3.3 Alternative Test Methods: Other test metho ds demonstrated to provide

results that are acceptable for purposes of determi ning compliance with Section 6.3.2, after review and approved in writing by the staffs of the District, ARB and EPA, may also be used. 4601 - 28 

6.3.4 Methacrylate Traffic Marking Coatings: Ana lysis of methacrylate

multicomponent coatings used as traffic marking coa tings shall be conducted according to a modification of EPA Method 24 (40 CFR 59, subpart D, Appendix A). This method has not been a pproved for methacrylate multicomponent coatings used for other purposes than as traffic marking coatings or for other classes of mu lticomponent coatings.

6.3.5 Flame Spread Index: The flame spread index of a fire-retardant coating

6.3.6 Fire Resistance Rating: The fire resistanc e rating of a fire-resistive

coating shall be determined by ASTM E119-07, “Stand ard Test Methods for Fire Tests of Building Construction Materials” (see Section 3.0, Fire-Resistive Coating).

6.3.7 Gloss Determination: The gloss of a coatin g shall be determined by

ASTM D523-89 (1999), “Standard Test Method for Spec ular Gloss” (see Section 3.0, Flat Coating, Nonflat Coating, and Non flat-High Gloss Coating).

6.3.8 Metal Content of Coatings: The metallic conte nt of a coating shall be determined by SCAQMD Method 318-95, Determination o f Weight Percent Elemental Metal in Coatings by X-Ray Diffra ction, SCAQMD Laboratory Methods of Analysis for Enforcement Samp les (see Section 3.0, Metallic Pigmented Coating, Aluminum Roof Coating and Faux

Finish.

6.3.9 Acid Content of Coatings: The acid content of a coating shall be

determined by ASTM D1613-06, “Standard Test Method for Acidity in

Volatile Solvents and Chemical Intermediates Used i n Paint, Varnish, Lacquer and related products” (see Section 3.0, Pre -Treatment Wash Primer).

6.3.10 Drying Times: The set-to-touch, dry-hard, dry-to-touch and dry-torecoat times of a coating shall be determined by AS TM D1640-95, “Standard Test Methods for Drying, Curing, or Film Formation of Organic Coatings at Room Temperature” (see Section 3.0, Quick-Dry Enamel and Quick-Dry Primer, Sealer and Undercoater ) The tack-free time of a quick-dry enamel coating shall be determi ned by the Mechanical Test Method of ASTM D1640-95. (Category deleted effective January 1, 2011.) 4601 - 29 

6.3.11 Surface Chalkiness: The chalkiness of a s urface shall be determined

using ASTM D4214-98, “Standard Test Methods for Eva luating the Degree of Chalking of Exterior Paint Films”(see Sec tion 3, Specialty Primer, Sealer and Undercoater). (Category deleted effective January 1, 2011.)

6.3.12 Exempt Compounds—Siloxanes: Exempt compou nds that are cyclic,

branched, or linear completely methylated siloxanes , shall be analyzed as exempt compounds for compliance with Section 6 by B AAQMD Method 43, “Determination of Volatile Methylsiloxanes in S olvent-Based Coatings, Inks, and Related Materials,” BAAQMD Manual of

Procedures , Volume III, adopted 11/6/96 (see Section 3.0, Vol atile Organic Compound, and Section 6.3.2).

6.3.13 Exempt Compounds—Parachlorobenzotrifluorid e (PCBTF): The exempt

compound parachlorobenzotrifluoride, shall be analy zed as an exempt compound for compliance with Section 6 by BAAQMD Me thod 41, “Determination of Volatile Organic Compounds in Sol vent Based Coatings and Related Materials Containing Parachlor obenzotriflouride,” BAAQMD Manual of Procedures , Volume III, adopted 12/20/95 (see Section 3.0, Volatile Organic Compound, and Section 6.3.2).
