ASTM D2829 – Standard Practice for Sampling and Analysis of Existing Built-Up Roof Systems

Description:

Significance and Use

5.1 This practice is for the sampling and analysis of existing built-up roof systems. For roofs under construction, use Practice D3617/D3617M.

Scope

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

1.1.5 Surfacing.

Note 1: This procedure is for the investigation of existing roofs and is not intended for new construction inspection.

1.2 This practice is applicable to both 914 mm [36 in.] and 1000 mm [39³/₈ in.] wide felt rolls.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
