Press Release Summary:
ASTM D7910, Practice for the Collection of Fungal Material from Surfaces by Tape Lift, helps avoid inconsistencies by describing correct way to collect accurate tapelift sample. According to ASTM member John M. Neville, tapelift samples are less expensive, less time consuming, and less labor intensive to collect and deliver than swab, bulk, or dust cassette samples. Users will include indoor environmental quality investigators, house inspectors, and certified industrial hygienists.
Original Press Release:
ASTM Tape-Lift Fungal Material Collection Standard Will Aid in Mold Sample Analysis
Taking a tapelift sample is one of the main practices used by indoor environmental quality investigators for detecting whether mold structures (for example, spores and hyphae) have either settled onto or colonized the surface. Despite the popularity of the method, there can be significant inconsistency in how tape lifts are collected.
A new ASTM standard, ASTM D7910, Practice for the Collection of Fungal Material from Surfaces by Tape Lift, addresses such inconsistencies by describing the correct way to collect a tapelift sample. ASTM D7910 will help investigators perform more accurate tapelift samples, according to ASTM member John M. Neville, senior mycologist and technical director, laboratory services, Bureau VERITAS North America Inc.
“The practice provides a simple and clear way to collect surface samples that may have mold contamination,” says Neville. “A tape lift is one of the main types of surface samples the consultant will collect.”
According to Neville, when done properly, tapelift samples are less expensive, less timeconsuming and less laborintensive to collect and deliver than swab, bulk or dust cassette samples. “Tapelift sampling may be a major step in a mold investigation to see if there is a mold problem and a potential building or health concern,” says Neville.
In addition to indoor environmental quality investigators, house inspectors and certified industrial hygienists will use ASTM D7910. Analytical laboratories will have an easier time performing tests on samples collected in accordance with ASTM D7910.
ASTM D7910 is under the jurisdiction of Subcommittee D22.08 on Sampling and Analysis of Mold, part of ASTM International Committee D22 on Air Quality. All interested parties are invited to participate in the standards developing activities of D22.08. The following are among the proposed standards D22.08 is currently developing:
• ASTM WK22872, Practice for Collection of Total Airborne Fungal Spores Via Inertial Impaction Methodology;
• ASTM WK28565, Practice for Collection of Cultural Airborne Fungi by Inertial Impaction Systems; and
• ASTM WK32489, Practice for Developing and Performing a Sampling Strategy to Collect Meaningful Data During the Assessment of Fungal Growth in Buildings.
