HDA 120 – Hardness and Density Automation Test System

The DIN ISO 48 standard outlines the procedure for performing a Shore A hardness test, which measures the resistance of a rubber material to indentation. The test involves applying a defined force to a standardized indenting tool and measuring the depth of the resulting indentation. The Shore A hardness value is then calculated based on the depth of the indentation. The specimen should be a flat and uniform piece of rubber or elastomer material. The specimen thickness should be at least 6 mm (0.24 in) and should be sufficient to allow the indenting tool to penetrate the surface without bottoming out on the support surface. The Shore A durometer used for testing should be calibrated before the test to ensure accurate and consistent results. The hardness value is reported in Shore A units, which range from 0 to 100. A higher Shore A value indicates a harder material, while a lower value indicates a softer material.

The ISO 2781 test method involves measuring the mass of a test specimen and its volume. The mass of the specimen is determined using a balance, while the volume is determined by either measuring the displacement of a liquid or by measuring the dimensions of the specimen and calculating the volume using geometric formulas.

The ISO 2781 standard outlines the specific test conditions and requirements for performing the density test, including specific test equipment and procedures for specimen preparation, handling, and testing. The test specimen should be a representative material sample, free from air bubbles or voids, and have a known weight. You also need to weigh the specimen on a balance of suitable accuracy and record the weight. To calculate the specimen's density, divide its weight by its volume. The density is usually expressed in grams per cubic centimetre (g/cm3) or kilograms per cubic meter (kg/m3).

The ISO 1183 standard has been adopted by many countries around the world, including the United States, Canada, and the EU. The test method involves measuring the mass of a test specimen and its volume. The mass of the specimen is determined using a balance, while the volume is determined by either measuring the displacement of a liquid or by measuring the dimensions of the specimen and calculating the volume using geometric formulas.

The ISO 1183 standard outlines the specific test conditions and requirements for performing the density test, including the use of specific test equipment and procedures for specimen preparation, handling, and testing. It also provides guidelines for reporting test results and includes information on calculating the test results' uncertainty.

The volume of the specimen can be determined using one of two methods:

• Liquid displacement: Submerge the specimen in a liquid of known density and measure the volume of the displaced liquid using a graduated cylinder or other suitable equipment.
• Dimensional measurement: Measure the dimensions of the specimen using a suitable instrument, such as a micrometre or calliper, and calculate the volume using geometric formulas.

ASTM D1817 is a standard test method for rubber products. It specifies the determination of the specific gravity of raw or unvulcanised rubber.

The specific gravity of a rubber material is a physical property that provides valuable information about the composition and quality of the material. It is the ratio of the mass of a given volume of the material to the mass of an equal volume of distilled water at a specified temperature.

What is the procedure? ASTM D1817 involves measuring the mass of a sample of rubber material and then determining the volume of the sample by immersing it in a liquid displacement medium, typically water. The specific gravity is then calculated by dividing the mass of the sample by the volume displaced by the sample.

The test method specifies several variables that must be controlled during the test. These variables are the temperature and timing of the measurements, the cleanliness and temperature of the liquid displacement medium, and the size and shape of the sample.

HDA 120 complies with ASTM D1817 Standard.

After the hardness measurement, a pneumatic gripping system transports the samples to a transfer point for density determination. Initially, the weight of the sample is determined in the air to calculate density. Subsequently, the gripping system transfers the sample to another station where it is deposited. A cylinder immerses the sample entirely underwater in a container filled with distilled water, and the water level is checked and adjusted if needed for each measurement. The cylinder moves the water bath up at least twice to eliminate air bubbles, and the current water temperature is recorded. The number of weightings in water can be increased to obtain more precise results. The highest wet weight is used to calculate the density.

The gripping system for density determination is designed with a forced ejection feature to prevent samples from sticking to the gripper. Once the density is determined, a separate gripping system picks up and ejects the sample, preventing potential water carryover. This gripping system also has a forced ejector feature to ensure no sample gets stuck.

The Impress Protection of HDA 120 is IP21.

IP21 (Ingress Protection 21) is a rating system that defines the level of protection provided by an enclosure against the ingress of solid objects and dripping water. The IP rating system is a standard defined by the International Electrotechnical Commission (IEC).

In the case of IP21, the first digit "2" indicates that the enclosure provides protection against the ingress of solid objects larger than 12.5mm, such as fingers or small tools. The second digit, "1," indicates that the enclosure provides protection against vertically dripping water.

In practical terms, IP21 is a relatively low level of protection and is often found in indoor environments where the equipment is not exposed to harsh conditions. Enclosures with IP21 protection are not sealed against dust or water spray and may not be suitable for use in dusty or wet environments.

The Impress Protection of HDA 120 is IP21.
