C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. Lapped edges of adjacent layers shall be staggered. Flexural strength, ultimate—22 psi MPa. A Maximum dimensions 2 in. The resin matrix is applied by various methods, including brush, roller, or spray gun.
Tensile strength and tangent modulus of elasticity, flexural strength, glass content, thickness, hardness, chemical resistance, and surface flame-spread classification tests shall be performed to conform to the specified requirements. When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. D Test Method D Test Method D NOTE 5—Maximum flame spread designation by Test Method E 84 relates to measurement and description of the properties of materials, products, or systems in response to heat and flame under controlled laboratory conditions and should not be considered or used for the description or appraisal of the fire hazard of materials, products, or systems under actual fire conditions.
Laminate designation from Table 3 shall consist of the abbreviation RTP followed by 1 type in Roman numerals; 2 class in capital letters followed by FS if required; 3 grade consisting of five Arabic numbers to designate minimum levels of physical properties and 4 thickness designated by Arabic number in decimal inches or ALL, if properties apply to all thicknesses.
However, results of this test may be used as elements of a fire risk assessment that takes into account all the factors that are pertinent to an assessment of the fire hazard or a particular end use. Current edition approved Oct.
This specification is limited to fabrication by contact molding. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
