Anotace textu normy ASTM D178-22 :
This specification covers the acceptance testing of insulating rubber matting that are used as a floor covering for the personal protection of workers. The sheeting shall be made from any elastomer or combination of elastomeric compounds. Two types of matting, differing in chemical and physical characteristics, are provided and are designated as Type I, which has been properly vulcanized, and Type II, which has one or more of the following special properties: (A) ozone resistance; (B) flame resistance; and (C) oil resistance. Five classes of matting, designated as Classes 0, 1, 2, 3, and 4, are assigned according to electrical protection characteristics. When evaluated in accordance with the test procedures detailed herein, the matting shall adhere to the following property requirements: electrical properties such as phase-phase maximum use voltage, AC and DC proof-test voltages, AC and DC dielectric breakdown test voltages, and AC and DC electrode clearances; an physical and chemical properties such as moisture absorption, oil resistance, tensile strength, tension set, elongation, resistance to accelerated heat aging, and flame resistance.

| X1.3?Significance and Use
X1.3.1?Tests made on a cellular plastic under conditions herein prescribed can be of considerable value in comparing the rate of burning and/or extent and time of burning of different materials, in controlling manufacturing processes, or as a measure of deterioration or change in burning characteristics prior to or during use. X1.3.2?This test method is not intended to be a criterion for fire hazard. The fire hazard created by materials depends upon the form and end use of the material. Assessment of fire hazard includes, but is not limited to, many factors, such as, ease of ignition, burning rate, flame spread, fuel contribution, intensity of burning, and products of combustion. |

1.1?This specification covers acceptance testing of rubber insulating matting for use as a floor covering for protection of workers. 1.2?Two types of matting, differing in chemical and physical characteristics, are provided and are designated as Type I and Type II matting. 1.3?The following safety hazards caveat applies only to the test method portion, Sections 17 to 19, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1:?Rubber insulating matting should remain flexible for
use through normal temperature ranges.
Note 2:?Rubber as used in this specification is a generic term
that includes elastomers and elastomer compounds, regardless of
origin.
1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
