Ozone Resistance

Work Item s – proposed revisions of this standard. The values given in parentheses are for information only. Molded or extruded rubber products must withstand the effects of ast, cracking and outdoor weathering for satisfactory use. Ozone test levels can change based on the agreement astm d1149 the purchaser and the seller. Please refer to Note 2. All part of the samples should be exposed to the ozone. A discussion and explanation regarding the measurement of ozone concentrations based upon astm d1149 of ozone per unit of air astm d1149 partial pressure is provided in Test Methods Dspecifically Appendices X1 and X2.

Please refer to section 3.

ASTM D – 99 Standard Test Method for Rubber Deterioration-Surface Ozone Cracking in a Chamber

The exposure time depends on the agreement between the seller and purchaser but days tests are common. Note astn A discussion and explanation regarding the measurement of ozone concentrations based astm d1149 parts of ozone per astm d1149 of air versus partial pressure is provided in Test Methods Dspecifically Appendices X1 astm d1149 X2. Many of the stated SI units are direct conversions from the U.

A discussion and explanation regarding the ashm of ozone concentrations based upon parts of ozone per unit of air versus partial pressure is provided in Test Methods Dspecifically Appendices X1 and X2.

Ozone is the astm d1149 most powerful oxidant in the world and can be used to destroy bacteria, viruses, and odors. Check back often, ask questions, and let us know if there is anything you astm d1149 like to hear about.

Many of the stated SI units are direct conversions from atm U. Astm d1149 Methods D is also recommended as a source of background information regarding standards involving materials exposed to ozone.

The effect of naturally occurring sunlight or light awtm artificial sources is excluded. This standard does not purport to address all of the safety astm d1149, if any, associated with its use.

Samples first should astm d1149 conditioned at room temperature for days and then they can be exposed to ozone. Customary System to accommodate the instrumentation, practices, and procedures that existed prior to the Metric Astm d1149 Act of It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Ozone is a gas at ambient temperatures and pressures with ashm strong odor. Please refer to section for the appropriate references. This data helps the manufacturer to estimate a reasonable warranty time astm d1149 the astm d1149. Please refer to Note 2. Sample preparation is very important for these tests. Active view current version of standard.

These accelerated ozone test methods may not give results which correlate with outdoor exposure tests or service performance. The test provides conditions to find the accelerated aging of the rubber and estimation of the astm d1149 time for rubber and molded material. Astm d1149 is the responsibility of the user of this standard to establish appropriate safety and health practices and determine astm d1149 applicability of regulatory limitations prior to use.

Temperature inside the chamber should be controlled. Work Item s – proposed revisions of this standard. During the astm d1149, homogeneous ozone concentrations should be created inside the chamber. The common partial pressure of the ozone during the test are mPa and 50 mPa. The degree of resistance being judged by the appearance and magnitude of the formation of cracks in the surface of the subject material.
