Standard Test Method for Detection of Lead in Paint by Direct Aspiration Atomic Absorption Spectroscopy
 N D4834

Annotation

This test method is intended as a screening test to determine if the solids in a paint contain more than 0.06 % lead. The test described can differentiate between 0.05 and 0.06 %. Paints giving a result greater than 0.05 % should be analyzed quantitatively for lead using Test Method D3335. This test method provides a more definitive and reliable screening test than Test Method D3618.

There is no reason to believe that higher levels of lead could not be determined by this test method provided that appropriate dilutions and adjustments in specimen size and reagent quantities are made.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Метод стандартной пробы для обнаружения лидерства в краске прямой спектроскопией атомного поглощения стремления

Этот метод испытаний предназначается как ситовый анализ, чтобы определить, содержат ли твердые частицы в краске свинец на больше чем 0.06%. Описанный тест может дифференцироваться между 0.05 и 0.06%. Краски, дающие результат, больше, чем 0.05%, должны быть проанализированы количественно для лидерства с помощью Метода испытаний D3335. Этот метод испытаний обеспечивает более категорический и надежный ситовый анализ, чем Метод испытаний D3618.
