Expected Expansion Contraction of Maple Due to Environment
This online tool is being released as part of Cross-Tech’s goal of making technologies available to the entire sport market. This calculator enables users to estimate how much Maple will expand and contract when between two given moisture content. NOTE: This tool is informative. It’s results are provided as an educational tool. All results are […]
Maple Equilibrium Moisture Content Calculator
Cross-Tech, ASET Services’ new division, is focused on making new technology available to the market. Cross-Teck is providing the sports surface industry with an informative tool to calculate the Equilibrium Moisture Content, or EMC, of the maple components of hardwood area elastic sport and dance floors. The EMC represents the equilibrium moisture content of […]
A guide to Cross-Tech Standards
The standards developed within Cross-Tech are modeled on ASTM Standards in the format and grouping. They provide a starting point for the development of official ASTM or other international standards. Cross-Tech standards are identified by group. For example CT-QM1100 (2024) is a ‘Quality Method’ that for measuring surface elevation irregularity. Each standard designation has a […]

Developing a more holistic approach to sport/dance surface safety using HIC and G-max testing.
The sports industry has been testing sports surfaces since the 1980’s. However, very little has changed in the last 45 years. Those tests, and today’s focus exclusively on low-energy, lower-extremity (leg/foot) – surface impacts. Anyone who has watched a practice, game, or performance knows that other impacts, specifically falls happen, and yet our traditional standards […]
A novel method of quantifying uniformity in Sport and Dance Surfaces
How uniform is your current sport or dance surface? How uniform are the surfaces you are considering for your new project? There is no way to tell using existing standards or performance rules. ASET believes that is a clear oversight by the entire manufacturing, testing, and architectural community. We completed a preliminary research project to […]
What is a dead-spot on a basketball court?
By: Paul W Elliott, PhD, PE Before discussing dead-spots, I want to briefly address field performance. If an architect, or owner, is concerned about the performance of individual installations, the specification must clearly state the performance levels that will be delivered and considered acceptable. Current North American specifications are vague and never state that the […]
When is a test report too old? – ASET’s updated position on suggested retest dates.
Note – Applies to reports issued after 2023. In the past, ASET Services chose to include suggested retest dates on our suitability reports. We felt this was an important feature for those using our reports that would help to insure that the results were reasonably current. First, we were the only lab that we know […]
