121.75.8679.166529
2) if accessible at a position of 600 mm or more above ground when tested in accordance with D.2.2, depending on the angular orientation range of the opening (see Figure D.4), shall conform to the fol- lowing:
⎯ Range 1: (template centre line ± 45° from vertical); when the template apex contacts the base of the opening, the depth of the opening shall be less than the length of the template to the under- side of the shoulder section.
⎯ Range 2: (template centre line from horizontal to + 45°); when the template apex contacts the base of the opening, the depth of the opening shall be less than the ‘A’ portion of the template. If the depth of the opening is greater than the ‘A’ portion of the template all parts of the opening above the ‘A’ portion shall also allow insertion of the shoulder section of the template or probe D.
⎯ Range 3: No template test requirements.
