This standard provides a unified test method for determining the insulation resistance of vulcanized rubber and thermoplastic rubber. It no longer distinguishes between volume resistance and surface resistance but measures their combined value, making it suitable for highly insulating rubber samples with resistance values greater than 10^8Ω. Due to its simple sample preparation, this standard method is primarily intended for applications that do not require high precision but need rapid qualitative assessment of the insulating properties of materials. The test apparatus mentioned in the standard must be capable of providing a stable DC voltage and determining the resistance value using either a bridge method or by measuring current and voltage. Relevant supporting instruments include guidelines for calibrating test equipment and potentially used electronic analytical balances.
