At a glance
Decide PTFE from the 260 continuous-service shorthand note and the figure 260 in Safety & fire class. Use Polyethylene in Measured properties only as contrast. A shopping guess that drops 260 does not replace the dossier you can already open.
Atlas Verification Checklist
0 / 4 verifiedCheck each criteria to confirm findings against the atlas verdict.
Open the existing chapter · PTFE / continuous-service shorthand (260)
Open the Safety & fire class chapter of PTFE and write 260 beside 260 on the continuous-service shorthand note before you accept a shopping guess. A figure that leaves that chapter is no longer the basis of the decision you can defend.
Keep the figure attached · PTFE / continuous-service shorthand (260)
Keep 260 attached to PTFE and to the continuous-service shorthand note in Safety & fire class. If a shopping guess moves the figure onto Polyethylene or onto a different year, put it back on the page that already exists.
Stay inside the limit · PTFE / continuous-service shorthand (260)
This is a heat, fire, or flex decision, not a shopping list, and alloy or code can move the safe choice. The continuous-service shorthand note is a way to read PTFE around the figure 260. It does not add a method, a rank, a cure, or a promised result beyond that page.
Use the second page as contrast · PTFE / continuous-service shorthand (260)
Open Polyethylene in Measured properties only to see a different existing page. Do not let that page supply missing facts for the 260 continuous-service shorthand note on PTFE. Two dossiers side by side are still two dossiers.
This is a heat, fire, or flex decision, not a shopping list, and alloy or code can move the safe choice. Check 260 on PTFE in the Safety & fire class chapter before you act on a shopping guess.
Does the continuous-service shorthand note replace the PTFE dossier?
No. The note tells you to read the Safety & fire class chapter of PTFE first and to keep 260 beside 260. The dossier remains the source.
Can Polyethylene override the figure 260?
No. Polyethylene is only a contrast in Measured properties. It cannot erase 260 on the continuous-service shorthand note.
What if a newer shopping guess ignores 260?
Keep both dates. A later shopping guess does not delete 260. Return to the Safety & fire class chapter and write down the clash instead of keeping the louder version.
