18、decrease (unaged to aged) in tensileproperties.4. Test Methods4.1 Vertical Static Load TestThe ladder shall be mountedas intended and subjected to a vertical static load of three timesthe rated load to evaluate the hook or anchoring, rung/step, andrung/step support components. The loads shall be eve

19、nlydistributed along length of the ladder, with a maximum of250 lb (113 kg) per rung, for 1 min. Following the test, theladder shall be examined for evidence of failure.4.2 Horizontal Static Load TestThe ladder shall bemounted as intended and subjected to a horizontal static load of200 lb (91 kg) to

20、 evaluate the hook (for portable ladders) orpermanent structural attachment (for permanent ladders) andstandoff components. The load(s) shall be applied at the pointwhere it would cause the greatest stress on the component for1 min. Following this test, the components shall be visuallyexamined for e

21、vidence of failure.4.3 Rung/Step Strength TestRungs/steps shall be mountedas intended to the side supports and subjected to a static loadof 750 lb (340 kg) applied at the center of the rung/step of a4-in. (10-cm) width for 1 min. Following the test, the rung/stepand side support shall be visually ex

22、amined for evidence offailure.4.4 Rung/Step Support Shear TestRungs/steps shall bemounted as intended to the side supports and subjected to astatic load of 750 lb (340 kg) applied to the rung/step of a 4-in.(10-cm) width immediately adjacent to the side support for 1min. Following the test, the rung

23、/step and side support shall bevisually examined for evidence of failure.4.5 Deployment Test:4.5.1 A variety of able-bodied individuals who have noprior knowledge of the product shall deploy and use the ladderthrough a window opening as defined and instructed by themanufacturer. Each test person sha

24、ll be evaluated for theirability to follow the instructions correctly, install the ladder(for portable ladders), deploy the ladder, and climb through thewindow and down the ladder. The deployment shall be timed.4.5.2 All members of the testing group shall accomplishdeployment through an opening in 1

25、 min. or less.NOTE 1The time period shall start at the time the person grasps theladder and shall end when the ladder is fully deployed (as intended foruse).4.6 Abnormal Operation TestA representative sample ofthe ladder shall be mounted as intended and subjected to thefollowing test: A 250-lb (113-

26、kg) load shall be placed 10 ft(3.0 m) below the hooks or permanent structural attachment.The bottom end of the ladder shall be displaced 10 to the rightfrom vertical. The ladder shall be evaluated for evidence ofslipping, disconnection, or any other hazardous conditions withrespect to attachment to

27、the window sill or permanent struc-tural attachment.5. Labels5.1 If any assembly by the consumer is required, the label inFig. 1 shall be visible on two opposite sides of the finalpackage.
