Standard Practice for Sampling and Analysis of Existing Built-Up Roof Systems
5.1 This practice is for the sampling and analysis of existing built-up roof systems. For roofs under construction, use Practice D3617.
1.1 This practice is a guide for removing test specimens from existing built-up roofing systems in the field and for determining the approximate quantities of the components of that specimen (Note 1). Components determined may be:
1.1.1 Insulation components when they are part of the roof membrane system,
1.1.2 Plies of roofing felt,
1.1.3 Interply layers of bituminous material,
1.1.4 Top coating, and

1.3 The values stated in SI (metric) units are to be regarded as standard.
1.4 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 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
