What is Astm D1927?
Astm D1927 is a standard test method for determining the thickness of plastic film and sheeting using a micrometer. It was developed by ASTM International, an organization that sets standards for various materials, products, systems, and services. Astm D1927 was first published in 1948, and has been revised several times since then. The latest version of Astm D1927 was issued in 2019.
Astm D1927 covers plastic film and sheeting with a nominal thickness of 0.25 mm (0.010 in.) or less. It applies to single-layer or multilayer materials that are homogeneous or nonhomogeneous, transparent or opaque, smooth or embossed, flat or textured. Astm D1927 does not apply to coated, laminated, or perforated materials, or materials that have surface irregularities that interfere with the measurement.
Applications and benefits of Astm D1927
Astm D1927 is widely used in various industries and fields that involve plastic film and sheeting, such as packaging, agriculture, construction, medical, automotive, aerospace, electronics, etc. Astm D1927 helps to ensure the quality, performance, safety, and compliance of plastic film and sheeting products. Some of the benefits of using Astm D1927 are:

How to Use Astm D1927?
To use Astm D1927, you need to follow the requirements and procedures of the standard, and use the appropriate equipment and materials. Here are the main steps to use Astm D1927:
Requirements and procedures of Astm D1927
Select a representative sample of plastic film or sheeting that has a uniform thickness and is free of wrinkles, folds, creases, or other defects.
Cut at least five specimens from the sample, each with a minimum area of 25 cm (3.88 in.). Avoid cutting specimens from the edges or corners of the sample.
Condition the specimens at a standard temperature of 23 2C (73.4 3.6F) and a standard relative humidity of 50 5% for at least 40 hours before testing.
Use a micrometer that meets the specifications of Astm D1927, such as having a flat anvil and spindle with a diameter of at least 6.35 mm (0.25 in.), a pressure foot with a diameter of at least 9.53 mm (0.375 in.), and a force of 0.88 0.02 N (0.2 0.005 lbf).
Place the specimen between the anvil and the spindle, and lower the pressure foot until it contacts the specimen. Apply the force gradually and uniformly, and read the thickness to the nearest 0.001 mm (0.0001 in.).
Measure the thickness of each specimen at five different locations that are at least 6.35 mm (0.25 in.) apart from each other and from the edges of the specimen.
Calculate the average thickness of each specimen by dividing the sum of the five readings by five.
Calculate the average thickness of the sample by dividing the sum of the average thicknesses of all specimens by the number of specimens.
Report the average thickness of the sample to three significant figures, and indicate the units used.
Equipment and materials needed for Astm D1927
To use Astm D1927, you need to have the following equipment and materials:
