ASTM E37 Standard Test Methods for Chemical Analysis of Pig Lead
ASTM E37 is chiefly designed to determine whether such materials are suitable for use according to the compositional requirements. As with all the methods described here, it is assumed that all users will be trained analysts who can perform routine laboratory techniques proficiently and work in a well-equipped laboratory.

ASTM E37 Introduction
The chemical analysis of metals and alloys using these test methods is mainly used to check such materials against compositional requirements. It is taken as axiomatic that all who employ these methods will be trained analysts capable of competently and safely conducting routine laboratory tasks.
ASTM E37 Test Method
Dissolution of solvent
The sample is dissolved in a nitric–perchloric acid mixture, the solution is fumed and hydrochloric acid is added to precipitate lead chloride. The hydrochloric-perchloric acid solution is sucked up into the air-acetylene flame of an atomic absorption spectrophotometer.
Measurement of absorption
The amount of energy of the resonance line which is absorbed in the spectrum of each element is determined and compared with the energy from the calibration solutions containing the same element.
ASTM E37 Equipment and Sample Preparation
Sample Detail
Metals and alloys are the samples used for this test.
Sample Size
In ASTM E37, the lines used are Cu 324.7, Bi 223.0 Ag 328.0, and Zn 213.8 nm, and photometric measurement is done at about 550 nm.
ASTM E37 Results and Interpretation
ASTM E37 results are evaluated by comparing the absorption values that are obtained from the atomic absorption spectrophotometer. The concentration of the specific elements present in any of the metal or alloy samples is determined by comparing their absorption spectra with calibration standards. The recorded absorbance values are in proportion with the concentration of the particular metals in the sample and thus facilitate the determination of the sample composition.

Tests Related to ASTM E37
ASTM E37 is related to tests including ASTM B29 for refined lead, ASTM E29 for significant figures, and ASTM E60 for the spectrophotometry of metals.
Use of ASTM E37 Testing in Various Industries
This testing is widely popular in different industries due to its accuracy in the determination of the composition of metals and alloys. In the aerospace industry, it guarantees that materials used in the manufacture satisfy safety and performance requirements that are important in aircraft construction. It is used in the automotive industry to confirm the composition of the parts, improve quality assurance, and obey the standards. In construction, it helps in evaluating the properties of structural material and checks whether it meets the standard safety standards or not. In addition, the electronics industry applies these techniques for the identification of metals within circuits or components of devices to foster the production of durable electronics.
Materials Commonly Tested with ASTM E37
This test standard materials include metals and alloys including aluminum, copper, zinc, lead, bismuth, and silver. These materials can be used in applications in many fields such as aerospace, automotive industry, construction, and electronics. The testing assists in confirming the compositional requirement hence appropriate for ascertaining the quality of the components used in these sectors.
Safety and Best Practices in ASTM E37 Testing
There are several important procedures for safety and best practices during and after ASTM E37 testing on specimens to provide a safe working environment in the laboratory. Where one handles hazardous chemicals, analysts should protect themselves from contacts by putting on gloves, lab coats, and safety goggles. Nitric and perchloric acids must be particularly well aerated since the vapor is toxic when inhaled. Some of the instruments for example atomic absorption spectrophotometers should be calibrated often to ensure accuracy.
Importance of ASTM E37
This test is important because it offers procedures through which it is possible to diagnose the compositional compatibility of metals and alloys hence suitable for application in the industries. The ASTM standard formulation of standard protocols for chemical analysis helps to meet industry standards and regulations and increases the safety and dependability of products.
