How to identify ISO 6162-1 and ISO 6162-2 flange connections and components

1 How to identify ISO 6162-1 and ISO 6162-2 flange port

See table 1 and figure 1, compare the key dimensions for identify ISO 6162-1 (SAE J518-1 CODE 61) port or ISO 6162-2 (SAE J518-2 CODE 62) port.

Figure 1 Port dimension for flange connections

From table 1, Dash-8 and -12 sizes, it is same screw dimensions and closely l7 and l10 for ISO 6162-1 and ISO 6162-2, so need inspect the l7 and l10 dimensions carefully, and measured with an accuracy of 1 mm or less.

2 How to identify ISO 6162-1 and ISO 6162-2 flange clamp

See table 2 and figure 2, figure 3, compare the key dimensions for identify ISO 6162-1 (SAE J518-1 CODE 61) flange clamp or ISO 6162-2 (SAE J518-2 CODE 62) flange clamp.

If it is split flange clamp, inspect and compare l7, l12 and d6 dimensions.

If it is one-piece flange clamp, inspect and compare l7, l10 and d6 dimensions.

3 How to identify flange head

From table 3 and figure 4, compare the key dimensions for identify ISO 6162-1 (SAE J518-1 CODE 61) flange head or ISO 6162-2 (SAE J518-2 CODE 62) flange head.

And if there is an identification groove located on the circumference of the flange disk, see figure 4 blue marked, it is ISO 6162-2 flange head. (this mark is optional before, so not all of ISO 6162-2 flange heads have this mark)
