1.2.1 Limitation; performance This standard practice shall NOT be used to establish levels of ___.
American Society for Testing and Materials (ASTM) E119 UL: Underwriters Lab Inc; ULC: Underwriters Laboratories of Canada
2.2 SFRM Classification: sprayed-fire or cementitious This standard practice shall be applicable for the testing of ____ as either ______
mixture bearing the UL or ULC label.
Cementitious mixtures Typically consists of one or more binders, aggregates or fibers that are mixed with
water to form a SLURRY and conveyed through a hose to a nozzle where
compressed air is typically used to disperse the material into a spray pattern.
Spray fiber materials Typically consist of one or more binders, aggregates or fibers that are conveyed
by low-pressure air through a hose to a nozzle where the material is mixed with
ATOMIZED water and sprayed. (dry mix)

3.2.1.D ASTM E736; 80%; 50% Bond tests conducted in accordance with ___ indicate a minimum average bond
strength of ___ and a minimum individual bond strength of ___, when compared to
the bond strength of the SFRM as applied to clean uncoated ⅛ inch thick steel
plate. (3.2.1D)
Five bond (3.2.1D) The average and minimum bond stregth values shall be determined based on a
minimum of ___ tests conducted in accordance with ASTM E736 (3.2.1D)

the ______ has NOT been measured. (3.2.1.1)
3.2.1.1 untreated substrates; five bond The treated and____substrates shall be coated with SFRM, cured and subjected to
___ tests each, in accordance with ASTM E736. (3.2.1.1)
If condition 3.2.1D is not met (bond tests) it shall be acceptable to provide a mechanical bond by wrapping the structural
member with expanded METAL LATH having a weight of not less than 1.7 lbs per
yd2.
If any of the conditions 3.2.1A-C are not met mechanical break shall be provided. (p. 6)
A mechanical break shall be provided by mechanically fastening one or more minimum 1.7 lbs per yd metal lath strips to
the flange or web either by weld, screw or powder-actuated fasteners, on
maximum 12 in centers, on each longitudinal edge of the strip, so that the
clear spans do not exceed the limits established (3.2.1A-C)
