||Participation Invited to Technical Training on Natural and Artificial
Introduction to the Fundamentals of Weathering, a technical
training session on natural and artificial weathering will be
offered by the executive committees of ASTM D08 on Roofing, Waterproofing and Bituminous Materials, D35 on Geosynthetics, and C24 on Building Seals and Sealants during ASTM Committee Week in
Norfolk, Va., June 24-29. Two sessions will be offered at the
Norfolk Waterside Marriott Hotel:
Committee D08 will present on Sun., June 24, 3:00-5:00 p.m.;
Committees D35 and C24 will present jointly on Wed., June 27,
10:00 am-12:00 p.m.
The training is part of a larger research and liaison session
that Committee C24 is holding.
There are three main factors of weather that contribute to the
degradation of exposed materials: radiant energy from the sun,
temperature, and moisture, wrote Matthew McGreer, general manager,
Client Education, and Frederick P. Schall, manager, Standards
Program, both with Atlas Electric Devices Co., Chicago, Ill.
These forces work synergistically to cause physical and chemical
changes, continued McGreer and Schall, who will be session speakers.
Understanding these factors are critical when evaluating exposed
materials, developing an exposure test program, or choosing an
accelerated method of testing. This presentation will feature
specific features of various natural and accelerated weathering
test methods, discuss what factors of weather are most accentuated
by these methods, and provide a guide to determine appropriate
exposures based on the end-use application of a material.
Weathering is a fascinating topic that touches all products,
concluded Schall, a member of several ASTM committees.
Attendance is highly encouraged. For further technical information,
