The Type A Durometer for general
rubber (Normal hardness )<\/h3>\n<\/hgroup>\n

The mainstream product used world-wide for measuring various kinds of rubbers, and specified in the standards of JIS K 6253-3, ASTM D 2240, ISO 48-4, DIN53505, etc.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\u00a0 \u00a0 \u00a0 \u00a0 The Pressure foot in contact with the specimen is 44mm in width and 18mm in depth, wide enough to ensure accurate measurement.<\/p>\n

Another type of durometer with an 18mm diameter pressure foot is available. In addition, the Longer Pressure Foot Type (AL Type<\/a>) is applicable for measurement of narrow or concave specimens.<\/span><\/div>\n

\u00a0 \u00a0 \u00a0 \u00a0 Our product line consists of various types of durometers applicable to specific materials as indicated in the chart above.<\/p>\n

Type A Durometer (ASKER A type), conforming to JIS K 6253-3 is the most popular type of durometer for measuring rubber hardness.<\/p>\n

However, verification is recommended because a significant difference is estimated to be the largest when a durometer indicates measurement values from 10 to 90 points.<\/p>\n

For hard specimens for which Type A Durometer readings indicate more than 90 points, measurements should be undertaken using the Type D Durometer (ASKER D type). However, for soft specimens with measurements of less than 20 points, the ASKER C type or Type E Durometer (ASKER E type) should be used. The most important consideration in using durometers is to select the correct type for purposes of measurement according to the specimen.<\/span><\/div>\n
