Action Revisions Revised Editorial - no technical change A. Cockman Apparatu
2、s Required Stiffness Tester According to drawing Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 OC and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions
3、 unless otherwise specified. Procedure 1. Cut 6 specimens 300 x 50 mm in size, 3 in the longitudinal and 3 in the transverse direction 2. Place the specimen on the test equipment so that the smaller dimension is in line with the front edge of the platform. 3. Move the specimen forward in the directi
4、on of the centimetre scale without any additional load until the leading edge of the specimen just touches this scale. This procedure must be completed within 3 seconds. Record the value at the point that the specimen touches the scale. Evaluation Report the stiffness for both the longitudinal and t
5、ransverse specimens as the average of the three scale readings obtained in each direction. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
