Standard Test Methods for Vacuum Cleaner Hose—Durability and Reliability (Plastic)
SIGNIFICANCE AND USE
4.1 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) vacuum cleaner and extractor hoses for household use.
1.3 The following tests are included:
Section
Torsional Flex
6
Hot and Cold Flex with Aging
7
Abrasion, External Surfaces
8
Flex
9
Pull Test on Hose Fittings with Aging
10
Crush
11
Stretch Ratio
12
Extractor Hoses
13
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7 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.
