32、when examined and tested, they are found to have features that reduce the degree of protection required by this Standard.4.2 Materials4.2.1 Metal parts, including metal wire rope, shall show no evidence of corrosion that would affect their function after being subjected to the applicable test specif
33、ied in ASTM B117 or ISO 9227 for a period of 24 h of exposure and 1 h of drying, followed by a second period of 24 h of exposure and 1 h of drying.4.2.2 Components made of materials that can degrade as a result of exposure to sunlight or other environmental factors shall be protected against such de
34、gradation by proper shielding of the components or other suitable means.4.2.3 The material specifications and design of all components shall ensure their durability and reliability of operation in temperature extremes from 35 to +45 C (31 to +95F) and when subjected to normal handling in the field.4
35、.3 Fall arresters4.3.1 Fall arresters shall be designed and marked in a way that ensures that they are used with a lifeline in accordance with the manufacturers recommendations.3(Replaces p. 3, January 2012)Z259.2.5-12 2013 CSA GroupApril 20134.3.2 When used on a vertical lifeline, fall arresters sh
36、all prevent installation or operation in the wrong orientation (unless designed to operate in any orientation).4.3.3 When a fall arrester has been installed on a lifeline, it shall not come off the lifeline when moved up and down. Only deliberate action by the user shall allow the device to be remov
37、ed from the lifeline. After arrest, the device by itself shall not allow the unintentional release or further lowering of the individual.4.3.4 Fall arresters shall be free from sharp or jagged edges or other design features that could injure the user or damage the fall-arrest system during normal us

44、pril 20135.3.3.2 The test equipment shall be set up as shown in Figure 1, with the fall-arresting mechanism at such a height that the test mass will not touch the floor in a successful simulated fall. The fall arrester shall be attached to the applicable lifeline fastened to an independent anchor po
45、int at least 3 m (10 ft) above floor level. If attachment hardware is required for installation (e.g., wire rope lifelines on ladders), all additional hardware that would be used in a field application shall also be supplied with the fall arrester and the lifeline.5.3.3.3 The test mass shall be rais
46、ed to a height above the fall arrester and at a horizontal distance less than 300 mm (12 in) from the fall arrester.5.3.3.4 If the fall arrester can be oriented on a lifeline in different ways, it shall be tested in all orientations.5.3.3.5 The lifeline shall be anchored at the top end of the inclin
47、ed plane and the fall arrester shall be affixed to the lifeline at least 1.2 m (48 in) along the incline plane from the bottom edge. The test lanyard shall be connected to the fall arrester and project over the edge. The test mass shall be attached to the test lanyard and raised 1.2 m (48 in) (see F
48、igures 5A and 5B).5.3.4 Residual static strength testImmediately following completion of the dynamic strength test specified in Clause 5.3.3, the fall arrester and lifeline shall be subjected to an additional force of 2 kN (450 lb-f) for 10 min by adding 200 2 kg (440 5 lb) to the test mass.
