ASTM C271 Standard Test Method for Density of Sandwich Core Materials

ASTM C271 determines the density specific sandwich construction core materials. Core materials include continuous and discontinuous bonding surfaces such as balsa wood, foams and honeycomb etc. The test involves measuring the volume and mass of the specimens

GET STARTED

 Introduction 

ASTM C271 provides a standardized procedure for measuring the volume and mass of specimens and calculating their density and specific gravity. It ensures accurate and consistent measurements aiding in quality control and material selection processes. It specifies a standard method of obtaining sandwich core density data for design properties, material specifications, research and development applications, and quality assurance.

ASTM C271 test method offers a standard way to gather sandwich core density data for design attributes, material specifications, applications in research and development, and quality control.

ASTM C271 Test Procedure 

Specimen PreparationThe specimen is placed parallel facing plane surfaces and perpendicular sides.  notches, undercuts, rough surfaces, and uneven surfaces are to be avoided. lubricated precision sawing, milling, or grinding is used  for final dimensions. 
Test Setup and ExecutionThis test method consists of environmentally conditioning a sandwich core specimen, weighing the specimen, measuring the length, width and thickness of the specimen, and calculating the density.

ASTM C271 Test Specimens 

Specimen DetailsIt is important to ensure that the specimens are representative and properly prepared to obtain accurate density. The specimen preparation may results in data scattering by affecting joints, discontinuities, curvature, and surface roughness.
Specimen dimensionsThe size and shape of the specimens can be chosen based on the specific requirements of the material and testing equipment. However, test specimens shall have a square or rectangular cross-section. The recommended minimum specimen size is 300 mm (12.0 in.) in length by 300 mm (12.0 in.) in width, with the thickness equal to the sandwich core thickness

Results 

The results of ASTM C271 include the density of specific sandwich construction core materials. These values provide quantitative measures of the material’s mass and volume characteristics. Both the environmental circumstances in which samples are prepared for testing and the conditions in which the test is conducted effect the results directly. The observed densities of specimens examined in different places with differing levels of ambient moisture can change noticeably. However, the results are stated in mass per unit volume. 

Relevant Tests

The relevant ASTM tests of ASTM C271 include ASTM C559 (Bulk Density). These tests evaluate different aspects of the material’s density and specific gravity properties, complementing the information obtained from ASTM C271.
