8、 BS EN 23270:1991 ii BSI 08-1999 National foreword This British Standard has been prepared under the direction of the Pigments, Paints and Varnishes Standards Policy Committee, and is the English language version of EN 23270 “Paints and varnishes and their raw materials Temperatures and humidities f
9、or conditioning and testing”, published by the European Committee for Standardization (CEN). It is identical to ISO 3270:1984 “Paints and varnishes and their raw materials Temperatures and humidities for conditioning and testing”, published by the International Organization for Standardization (ISO)
10、. ISO 3270:1984 was previously published as Annex A to BS 3900 “Methods of test for paints” Part 0:1989 “General introduction”. BS 3900-0 is being amended and Annex A to that standard will be replaced by a reference to BS EN 23270. A British Standard does not purport to include all the necessary pro
