This standard includes three types:

1. Figure-8 blank

  also called spectable blank, is a pressure-retaining plate with one solid and one open end connected with a web or tie bar.

2. Paddle blank

  it's similar to the solid end for a figure-8 blank, it has a plain radial handle. It's generally used in conjunction with a paddle spacer in large sizes.

3. Paddle spacer

  It's simiar to the open end of a figure-8 blank, it has a plain radial hande. It is generally used in conjunction with a paddle blank.
