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 and health practices and determine the applicability of regulatory limitations prior to use.

TEST METHODS
6. Torsional Flex Test
6.1 Scope—This test method covers the determination of the adhesion of the reinforcement wire coating to the hose jacket, the
jacket strength, and the strength of the reinforcement wire for plastic hose with inside diameter from 1 to 2 in. (25 to 51 mm).
6.2 Apparatus—The apparatus shown in Fig. 1 is suitable for this test method with the following provisions:
6.2.1 Means to rotate test mandrel in a horizontal plane at 20 6 1 rpm, both clockwise and counter-clockwise.
6.2.2 Test weight of 48 6 1 oz (1360 6 28 g) with provision to attach to sample hose.
6.2.3 Suitable clamp to attach sample hose to mandrel that retains the hose without causing failure at the clamp during the test.
6.2.4 Test mandrel with diameter same as inside diameter of hose with 0.078 in. (2.0 mm) radius at the ends of the mandrel (see
Fig. 1).
6.2.5 Guide for weight to prevent hose sample from swinging during test cycle.
6.2.6 Instrument to measure cycles to failure or to a specified end point.
