This guide has been prepared to assist welding personnel with the preparation of welding procedures
required as part of their company certification to CSA Standards W47.1, W47.2 and W186.
The following three documents will be described:
(a) Welding Engineering Standards (Note: Only required for W47.2)
(b) Welding Procedure Specifications
c) Welding Procedure Data Sheets
There will be a brief description of the first two documents; however, this guide will focus on the preparation
of welding procedure data sheets.
Paradoxically, skin is both a primary barrier to systemic absorption of topically
exposed chemicals and a portal to systemic delivery of transdermal medicaments.
Knowledge of the factors that determine both extent and rate of chemical flux across
the skin is an important component of both toxicology and pharmacology studies.
The aim of this book is to provide current approaches and techniques by which
dermal absorption may be quantitated utilizing end points relative to these two
It will not have escaped the notice of anybody who happens to be living
in Europe at this time that the organisation of health care services has
been and continues to be in a seemingly permanent state of flux. In
some countries this is perhaps more noticeable than others, but no
health system is free of the challenge of change. The dynamic for this
process has been primarily, but not solely, one of controlling costs, but
the modernising of health services delivery within Europe has proved to
be not simply one of financial stringencies....
