A Class 1, or Class A, fire rating means that the building material is highly resistant to fire and does not spread flames quickly. In the flame-spread rating test, a score of 0 to 25 constitutes a Class 1 rating. The score is relative and balanced between asbestos cement sheet, with a score of 0, and pure red oak, with a score of 100.
A Class I vapor retarder is a material with a permeance less than 0.1. That definition may be difficult to understand without some additional context. A vapor retarder defined by ASTM E1745 is a material with a permeance ranging betweem 0.01 and 0.10 perms. Click to see full answer.
ASTM Levels • ASTM Level 1: Ideal for procedures in which there is low risk of fluid exposure (no splashes or sprays expected). • ASTM Level 2: Ideal for procedures in which there is moderate risk of fluid exposure (splashes or sprays can be produced). • ASTM Level 3: Ideal for procedures in which there is high risk of fluid exposure (splashes or
