Significado e uso
4.1 This test method provides basic engineering data that can be used to determine the amount of VOC delivered to the inlet of VOC control equipment. This procedure can be used to determine the amount of VOC produced from the coating in a flash area or oven and can be incinerated, although the same procedure can be followed when using other forms of VOC abatement.

4.2 A quantidade total de COV removida do processo pelo dispositivo de controle de COV é uma função da quantidade disponível fornecida pelo método de teste e da eficiência de remoção de COV do dispositivo de controle.

1.1 This test method describes the determination of the amount of volatile organic compounds (COV) released from applied waterborne automotive coatings that can be used for delivery to VOC control equipment. The determination is accomplished by measuring evaporative or dry weight loss of the newly coated test plate and analyzing the VOC or water content of the coating.

1.2 This test method is applicable to VOC released from application and baking operations after painting in simulated production processes or actual production facilities.

1.3 Symbols and calculations of several other methods for determining VOC: Practice D3960, EPA 450/3-88-018 and EPA 450/3-84-019 have been incorporated into this test method. Most of the notations and calculations used in this test method are unique because the test method uniquely deals with weight differences in applied paint samples that have been dried, cured, or solvent-added.

ASTM-D 6266-2017 “Determinação da Quantidade de Compostos Orgânicos Voláteis (COV) Emitido de revestimentos automotivos à base de água e a quantidade removida (Quantidade reduzida) de dispositivos de controle voc”

Observação 1: The importance of training and knowledge of the evaluated product to derive meaningful data from this test methodology is overstated. It is recommended that multiple practice runs and laboratory repeatability be evaluated before performing this test on test samples.

1.4 Values expressed in SI units shall be regarded as standard. Os valores dados entre parênteses são apenas para referência.

1.5 Esta norma não se destina a abordar todos, caso existam, preocupações de segurança associadas ao seu uso. It is the responsibility of any user of this standard to consult and establish appropriate safety and health practices and to determine the applicability of regulatory restrictions before using this standard.

1.6 Esta norma internacional é baseada nos princípios de padronização internacionalmente reconhecidos estabelecidos na Decisão sobre Princípios para o Desenvolvimento de Normas Internacionais, Diretrizes e recomendações emitidas pelo Comitê da OMC sobre Barreiras Técnicas ao Comércio.
