Standard Specification for Underlayment Felt Containing Inorganic Fibers Used in Steep-Slope Roofing
N D6757/D6757M REV A
Annotation
This specification covers (1) inorganic fiber-reinforced organic felt underlayment and (2) inorganic fiber-based felt for use as underlayment with steep-slope roofing products. The intent of this specification is to provide criteria for producing and evaluating underlayments with a significantly reduced tendency to wrinkle before or after the installation of steep roofing products.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
The following safety hazards caveat pertains only to the test method portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

Стандартная спецификация для Юндерлэмана чувствовала содержащий минеральные волокна, используемые в кровле крутого откоса
Эта спецификация покрытия (1) неорганический укрепленный волокном органический чувствовала underlayment и (2) неорганическое основанное на волокне использование, которому сопереживают, в качестве underlayment с кровельными продуктами крутого наклона. Намерение этой спецификации состоит в том, чтобы обеспечить критерии создания и оценки underlayments со значительно уменьшенной тенденцией сморщиться прежде или после установки крутых кровельных продуктов.
