PCA Test Methods Foreword

The test methods used by the pine chemicals industry are published primarily by three organizations,   ASTM International,   International Standards Organization  and the Pine Chemicals Association.   ASTM and ISO standard test methods  cover areas of wide industrial interest  including some for the pine chemical industry but do not include  many that are specific to the products and the processes of the  pine chemicals industry.

Some years ago the Pine Chemicals Association  remedied this by collecting and publishing Standard Test Methods for  Tall Oil Products.   The original publication has been updated once and now is is being updated again.

The major reason for this latest updating is the continuing changes in the regulations governing solvent use and the increased emphasis on laboratory safety.  

The original publication was limited to tall oil products and this latest update primarily pertains to tall oil but it does include a limited number of test methods related to turpentine.  In addition a Guide to Turpentine Test Methods is included as an appendix. To reflect this change the title has been changed from Standard Test Methods for Tall Oil Products to Standard Test Methods of the Pine Chemical Association.

This updating was made and approved by members of the PCA Testing Committee under the chairmanship of Donald Scott and Phil Hurd and with the support of James Russell.  

 

SAFETY

The procedures described in these test methods require the use of a wide variety of chemicals and laboratory techniques.  In order to keep the methods easy to follow, individual test methods do not address all the safety problems associated with their use.  It is the responsibility of the user of these standards to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

In order to ascertain the hazards associated with any of the chemicals mentioned in these test methods, the user should consult the Material Safety Data Sheet for that chemical. Also, the user should refer to their location's chemical hygiene plan to ascertain the appropriate personal protective equipment to where while carrying out these tests.
