Standard Test Methods for Rubber Deterioration—Reference and Alternative Method(s) for Determining Ozone Level in Laboratory Test Chambers

Importancia y uso:

4.1 General purpose and many specialty rubbers will undergo ozone cracking when exposed to ozone containing atmospheres, when the test specimens or actual use products are under a certain degree of tensile strain. Certain additives such as antiozonants and waxes inhibit or prevent this cracking. Various rubbers and rubber formulations containing such additives are customarily evaluated under static or dynamic tensile strain in laboratory ozone chambers. This standard provides for an accurate assessment of the ozone content of such chambers used in Test Methods D518, D1149, D1171, D3395 and ISO Standard 1431 I/II/III. For additional information on ozone analysis, refer to Code of Federal Regulations; Title 40 Parts 1 to 51.
