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 and extractor hoses will receive in normal use.

1.2 These test methods apply to plastic (regular and reinforced), nonelectric vacuum cleaner and extractor hoses for household use.

1.3 The following tests are included:

Section
Torsional flex6
Hot and cold flex with aging7
Abrasion, external surfaces8
Flex9
Pull test on hose fittings with aging10
Crush11
Stretch ratio12
Extractor hoses13

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 mathematical conversions to SI units that 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.
