General Discussion / Re: ISPM15 Audit critera / guidelines
« Last post by MichaelM on May 30, 2017, 10:19:18 AM »
APHIS (Agricultural Pant Health Inspection Service) is the US agency that oversees the ISPM program.  I know, we al thought an aphis was an insect a few years ago.

APHIS, in turn, delegates the implementation to the ALSC (American Lumber Standards Committee).

Grading agencies, such as WCLIB or WCLIB, get their authority to issue grade stamps from the ALSC.
Therefore, your grading agency is the go to organization. They will issue the authority for you to use the HT stamp.

Dry Kiln Control / New float style wet bulbs

New float style wet bulbs: is a flow meter still needed?
  • No, not if they are working correctly.  Although there may be a benefit of a visual flow indicator and an individual shut off per wet bulb

Drying Defects / Re: Agressive Schedules?
« Last post by DrykilnsMan on May 23, 2017, 10:23:34 AM »
Make sure your not running out of control, i.e. vents fully open & current wet bulb set points not being achieved. Same goes for dry bulb set points.

General Discussion / ISPM15 Audit critera / guidelines
« Last post by HencoV on May 12, 2017, 01:03:20 PM »
Does anyone here know where I can get hold of the actual ISPM15 audit guidelines that must be adhered to before a heat treatment facility can be certified to comply with the standard? Our government department that is supposed to do this cannot provide such a document, keep shifting the goal posts and keep and keep asking for ridiculous achievements to be accomplished...honestly..the inspector cannot tell the difference between a temperature probe and football.

My understanding is that is must be proven that the core temperature of the timber must be measured and recorded at 56 Deg C or above for 30 consecutive uninterrupted minutes.  Our inspectors are asking for up to 12 probes at different positions in the kiln of 7 x 4 meters holding less than 10 cubic meters....?

Please assist..

General Discussion / Dry Bulb & Wet bulb hygrometer or RH/EMC Probe for control
« Last post by HencoV on May 03, 2017, 08:51:37 AM »
Hi Guys,

I have always had some reservations about using RH/EMC probes instead of Wet Bulbs for control. This, in my opinion is probably because the controls I came across that uses RH/EMC control was very slow to react, and "over vented" from an early stage in drying. I suspect it was a lack of proper understanding of the programmer on the effect of RH on venting and energy usage. So..to put my own internal conflict at rest, I decided to run some tests

I'm busy running a comparison in one of our kilns using both Wet Bulb, as well as RH probe for control purposes to try and establish the best way forward.  I'll will post my findings here in a month or so.

In the mean time:What are your views, pros & cons of each of these technologies. From a control and accuracy point of view, which would you rate best? Share your experience please
