GENERAL TEST METHOD FOR DETERMINING SOLVENT LOSSES

FROM

SPRAY GUN CLEANING SYSTEMS

October 3, 1989

(AL/SPRYTST7)
I. SCOPE

This method covers the determination of solvent losses from cleaning systems used for the cleaning of spray guns and paint cups.RuleOperations)

1151 (Motor Vehicle and Mobile Equipment Non-Assembly Line Coating requires under paragraph (c)(3)(B) that effective January 1, 1990,

a person or facility shall not use VOC-containing materials for spray equipment cleanup unless an enclosed 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 an alternative 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 or less 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 are carried 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 may also comply directly with paragraph (c)(3)(B) if all cleaning steps are carried out inside the equipment.

will

The equipment to be evaluated and one of the approved equipment listed above be tested concurrently such that the cleaning cycles for each equipment are spread out evenly throughout the concurrent test period. An AECP also

Executive

requires the equipment manufacturer to obtain written approval from the Officer (Office of Operations) before the alternate equipment can be used. This document provides guidelines for obtaining the Executive Officers approval and test methods to be used for determining solvent losses from various types of spray-gun cleaning equipment.

II. APPLICATION PROCEDURE

1.

A test to concurrently determine solvent losses from the candidate equipment and from one of the approved equipment is required.

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

a test plan to the Office of Operations of the District for review. The test plan shall be prepared in accordance with the guidelines provided in this document.
p

t

ng laboratory approved by the District. The District

District

shall be notified at least 48 hours before the start of the test so that

a observer may be present.

5.

A final test report including all test data, calculations and results shall be submitted to the 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

modes.

method is intended to determine solvent losses during Active and Passive The Active mode comprises all steps carried out during

a cleaning operation. The Active Loss is expressed in grams of solvent loss per cleaning cycle. For the purpose of this test method,

a number 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 to be 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 at least three separate tests: Testing variability may require additional tests on

a case by case basis. The Passive mode represents the non-Active mode period when cleaning equipment sits idle between cleaning cycles and for extended periods such as weekends. Passive losses are

a result of natural evaporation of the solvent from the equipment. The Passive Loss is expressed in grams of solvent loss in the Passive mode per hour. For the purpose of this test the total Passive losses are determined for

a period of at least five (5) consecutive days by measuring the difference between the solvent weights at the beginning and at the end of the Passive mode test period. The Passive mode test shall be terminated at the end of the fifth day if the total solvent loss during this period is 600 grams or more. In case total solvent loss in five days is less than 600 grams, the test shall be extended until

a total solvent loss of 600 grams is achieved or up to

a total of fifteen (15) days whichever occurs first. The Passive Loss in grams per hour 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 can be operated under different conditions. In order to determine solvent losses for comparison purposes, test conditions need to be standardized. For the purpose of this test, the following conditions are fixed:

1. Cleanup solvent: Du Pont, Duco Refinish Thinner, 3642S

2. Although type of coating deposit can be reproduced for each test by using the same brand of coating, the quantity and the hardness of the coating
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.

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.
st 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.
