16 C.F.R. § 1260.2
(b) Requirements for rigid cord shrouds. If a custom window covering complies with paragraph (a) of this section by using a rigid cord shroud to make an operating cord inaccessible, the rigid cord shroud shall meet the requirements in section 6.3, of ANSI/WCMA A100.1—2018 and shall not have an accessible cord when tested for cord accessibility using the test methods defined in paragraphs (b)(1) and (2) of this section.
(1) Test methods for rigid cord shrouds: Center load test.
(i) Support each end of the rigid cord shroud, but do not restrict the rotation along the axial direction. Supports must be within 0.25 inches from the ends of the shroud as shown in figure 1 to this paragraph (b)(1)(i).
Figure 1 to Paragraph (b)(1)(i)—Rigid Cord Shroud Test Set-Up

(ii) Apply a 5-pound force at the center of the rigid cord shroud for at least 5 seconds as shown in figure 2 to this paragraph (b)(1)(ii).

(v) While continuing to apply the 5-pound force, determine if the cord(s) can be contacted by the cord shroud accessibility test probe shown in figure 3 to this paragraph (b)(1)(v). If the cord shroud accessibility test probe can touch any cord, the cord(s) are considered accessible.

(2) Test methods for rigid cord shrouds: Axial torque test.
(c) Requirements for cord retraction devices. If a custom window covering complies with paragraph (a) of this section using a cord retraction device, the cord retraction device shall meet the requirements in paragraphs (c)(1) through (4) of this section.
(d) Requirements for loop cord and bead chain restraining devices. If a custom window covering complies with paragraph (a) of this section using a loop cord and bead chain restraining device, the loop cord and bead chain restraining device shall meet the requirements in section 6.5, of ANSI/WCMA A100.1—2018 with an additional test as defined in paragraph (d)(l) of this section, and shall not form a hazardous loop when tested for a hazardous loop using the test methods defined in paragraphs (d)(2) and (3) of this section.
(2) Test methods for loop cord and bead chain restraining device: Center load test.
(i) Support each end of the loop cord and bead chain restraining device, but do not restrict the rotation along the axial direction. Supports must be within 0.25 inches from the ends of the shroud as shown in figure 4 to this paragraph (d)(2)(i).

(ii) Apply a 5-pound force at the center of the cord and bead chain restraining device for at least 5 seconds as shown in figure 5 to this paragraph (d)(2)(ii).
