Standard Test Methods for Vacuum Cleaner Hose—Durability and Reliability (Plastic Wire Reinforced)
SIGNIFICANCE AND USE
These test methods can be used by buyers of vacuum cleaner hose to specify the test criteria the hose must meet to be acceptable for their purposes.
SCOPE
1.1 These test methods cover the determination of the effect of anticipated stresses and strains that vacuum cleaner hoses will receive in normal use.
1.2 These test methods apply to plastic, wire-reinforced, nonelectric vacuum cleaner hoses for household use.
1.3 The following tests are included:
SectionTorsional flex6Hot and cold flex with aging7Abrasion, external surfaces8 Flex9Pull test on hose fittings with aging10Crush11
1.4 These test methods are individual tests as agreed upon between the hose and vacuum manufacturer.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathmatical conversions to SI units, which are provided for information only and are not considered standard.
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
