To comply with ASTM E83, a system must be verified using a calibration device (like a laser interferometer or a digital micrometer) that is significantly more accurate than the extensometer being tested. 1. Temperature Stabilization

Platforms like ANSI or IHS Markit.

is the most common requirement for determining the modulus of elasticity in metals.

Without a standardized verification process like E83, the data from a tensile test would be unreliable. 🔍 Key Classifications in ASTM E83 astm e83 pdf

The standard categorizes extensometers into "Classes" based on their maximum error and repeatability. When you review an ASTM E83 PDF, you will see a table detailing these requirements: Relative Error of Gauge Length Fixed Error (whichever is greater) ±0.00001 in. Class B-1 ±0.0001 in. Class B-2 ±0.0001 in. Class C ±0.001 in.

Many universities provide access to ASTM Compass for students and faculty.

Technicians take readings at various increments across the extensometer's range. This ensures accuracy at both small strains (near zero) and large deformations. 3. Reporting Results A verification report must include: The date of calibration. The specific classification achieved (e.g., Class B-1). The temperature during the test. The traceability of the calibration equipment. 📈 Why You Need the Official PDF 🔍 Key Classifications in ASTM E83 The standard
