SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT GENERAL TEST METHOD FOR DETERMINING SOLVENT LOSSES FROM SPRAY GUN CLEANING SYSTEMS October

3, 1989 (AL/SPRYTST7)—1—. GENERAL TEST METHOD FOR DETERMINING SOLVENT LOSSES FROM SPRAY GUN CLEANING SYSTEMS I. SCOPE This method coversthe determination

of solvent losses from cleaning systems used for the cleaning
of spray gunsand paint cups. Rule 1151 (Motor Vehicle and Mobile Equipment Non-Assembly Line Coating Operations) requires under paragraph (c)(3)(B) that effective January

1, 1990,

a personor facility shall not use VOC-containing materials for spray equipment cleanup unless anenclosed system

is used for cleaning. The system must totally enclose spray-guns, cups, nozzles, bowls, and other parts during washing, rinsing, and draining procedures. Rule 1151 under paragraph (h), Alternative Emission Control Plan (AECP), provides
analternative ror equipment, which does not directly comply with paragraph (c)(3)(B),

to comply under an equivalency plan. This plan implies that equipment not directly complying with the provisions

of (c)(3)(B) may comply with the rule if VOC emissions from such equipment
are equal orless than that from equipment directly complying with the provisions

of (c)(3)(B) under similar cleaning conditions. The following equipment have been determined

by the District
to directly comply with paragraph (c)(3)(B)

if all cleaning steps arecarried out inside the equipment: 1. Herkules Gun Washer and Recycler (GW/R) 2. Uni-Ram Cascade Model Numbers UG 2000, UG 3000, and UG 4000. Other enclosed equipment than that listed above mayalso comply directly with paragraph (c)(3)(B)

ifall cleaning stepsarecarried out inside the equipment. The equipment

tobe evaluated and oneof the approved equipment listed above will be tested concurrently such that the cleaning cycles for each equipment are spread out evenly throughout
the concurrent test period. An AECP also requires the equipment manufacturer

to obtain written approval from the Executive Officer (Office of Operations) before the alternate equipment canbe used. This document provides guidelines for obtaining the Executive Officers approval and test methods
tobe used for determining solvent losses from various typesof spray-gun cleaning equipment. II. APPLICATION PROCEDURE 1. A testto concurrently determine solvent losses from the candidate equipment and from oneof the approved equipment

is required. 2. The equipment manufacturer requesting• the District approval shall submit

atest plan tothe Office of Operations

of the District for review. The test plan shall be prepared

in accordance with the guidelines provided

in this document.-2- 3. The test plan shall be reviewed
by the District staff and an approval

to conduct the test will be given
if the test plan
is determined

tobe satisfactory. 4. The test shall be conducted

in accordance with the approved plan by an independent testing laboratory approved
by the District. The District shall be notified
at least 48 hours before the start of the testsothat
a District observer maybe present. 5. A final test report including
all test data, calculations and results shall be submitted

tothe District, Office of Operations,
for approval. 6. An approval
of the equipment will be issued
if the results of the test meet the requirement

of Rule 1151(h). III. INTRODUCTION This method

is intended

to determine solvent losses during Active and Passive modes. The Active mode comprises
all steps carried out during

a cleaning operation. The Active Loss
is expressed

in gramsof solvent loss per cleaning cycle. For the purpose
of this test method,

anumber
of cleaning cycles shall be carried out and the total solvent loss determined

by the difference between the initial and the final solvent weights
in the system. The number of cleaning cycles tobe carried out for the purpose
of this test shall be such that the total loss of solvent

is at least 600 grams.-The Active Loss
is calculated
by dividing total solvent loss by the number
of cleaning cycles and shall be the arithmetic average of atleast three separate tests: Testing variability may require additional tests onacase by casebasis. The Passive mode represents the non-Active mode period when cleaning equipment sits idle between cleaning cycles and for extended periods such asweekends. Passive losses are
aresult of natural evaporation

of the solvent from the equipment. The Passive Loss is expressed

in gramsof solvent loss in the Passive mode perhour. For the purpose
of this test the total Passive losses aredetermined
for
a period of atleast five (5) consecutive days by measuring the difference between the solvent weights
atthe beginning and atthe end of the Passive mode test period. The Passive mode test shall be terminated

atthe end of the fifth day if the total solvent loss during this period

is 600 gramsormore.In casetotal solvent loss in five days is less than 600 grams,the test shall be extended until

atotal solvent loss of 600 grams

is achieved
or uptoatotal of fifteen (15) days whichever occursfirst. The Passive Loss in grams perhour
is calculated

by dividing the total Passive loss by total number
of hours of the Passive mode test period. Spray gun clcaning systems
in industry canbe operated under different conditions.

In order to determine solvent losses for comparison purposes,test conditions need tobe standardized.
For the purpose
of this test, the following conditions arefixed: 1. Cleanup solvent: Du Pont, Duco Refinish Thinner, 3642S 2. Although type of coating deposit canbe reproduced
for each test by using the samebrand of coating, the quantity and the hardness
of the coating..3

C deposit are difficult
to reproduce.

In order to avoid this complexity, the spray gun and the cup to be used for test purposes will have no coating deposits. 3. Spray gun: Binks Model #7 4. Cup: Binks Model #81-350 IV. CRITERION FOR COMPLIANCE WITH RULE 1151(h) The candidate equipment shall be deemed
in compliance with the provisions

of Rule 1151(h)
if: 1. The Active solvent loss of the candidate equipment

is equal to or less than the Active solvent loss of at least one of the approved equipment, and 2. The Passive solvent ioss of the candidate equipment

is equal to or less than the Passive loss of at least one of the approved equipment, iid 3. The same approved equipment shall be used to demonstrate compliance with criteria

1 and
2 above.

C V. EqUIPMENT: There are two basic types of spray-gun cleaning equipment currently available on the market: once-through systems and continuous recycle systems. In once-through systems, cleanup solvent

is transferred

to the spray-gun cup from

a solvent container, flushed through the gun, and captured from the discharge
of the gun in a separate container
or in a solvent recovery device such as a condensing unit. In these systems, the exterior of the gun and the cup are generally cleaned by hand-wiping with solvent-soaked rags or with brushes, and thus, solvent loss goes directly
to the atmosphere. Examples
of once-through systems are Lighthall SC 1100 and SC 70 spray-gun cleaning systems. There are two types of continuous recycle systems: systems with only one solvent container (wash-cycle container) and systems with two solvent containers (wash- cycle and rinse-cycle containers).

In systems with only one solvent container, the solvent

is pumped from the container

to the gun and its parts and drained back to the same container.

In systems with two solvent containers, the final rinsing

is carried out inside the cleaning equipment with virgin solvent pumped from

a separate container after washing with wash solvent.
In either case, equipment does not comply with the specific language

in paragraph (c)(3)(B)

if any cleaning step is carried out outside an enclosed chamber. -Examples
of continuous recycle systems are Uni-Ram Cascade series models UG 2000, UG 3000 and UG 4000; Herkules Equipment Corporation Gun Washer and Recycler (GW/R); Safety Kleen Model 1107; Pacific Coast Lacquer PCL Unit ill; and Astro Pneumatic Gun Washer/Recycler.-4- VI. TEST PROCEDURE FOR RECYCLE SYSTEMS: Notes: (a) The analytical balances used in this test method shall be accurate and precise enough
to assure that the weight loss measured

is accurate within ±2% of the measured difference. (b) Room temperatures during Active and Passive mode testing shall be continuously recorded
on a temperature recorder. A. Active Loss 1. Weigh empty wash-solvent container, “A” grams. Record on Data Sheet
