What is the scope of ASTM E 1775-96?

• A. Field collection of dried paint samples for lead determination
• B. Ultrasonic extraction of paint samples
• C. Standard guide for evaluating performance of on-site extraction and field-portable electrochemical or spectrophotometric analysis for lead
• D. Preparation of dried paint samples for laboratory analysis

Answer: (C)

The main idea here is that this standard serves as a guide for evaluating how well on-site extraction methods and field-portable electrochemical or spectrophotometric instruments perform when testing for lead in paint. It isn’t about collecting samples in the field, it isn’t about a specific extraction technique like ultrasonic extraction, and it isn’t about preparing dried paint samples for laboratory analysis. Instead, it provides criteria and procedures for assessing the performance of those on-site, portable testing approaches—things like accuracy, precision, detection limits, reproducibility, and overall reliability of the field methods. That focus on evaluating how well field methods work in practice is what makes this option the best description of the scope.
