Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces LY/T 1321-1999 "cork paper test methods." Compared with LY/T 1321-1999, in addition to editorial changes outside the main
To technical changes are as follows.
--- The scope of an increase of roll-like cork paper;
--- Increased dumbbell specimen map;
--- Increased compression springback tester schematic;
--- Increased softness formula;
--- Increased resistance to boiling hydrochloric acid test.
This standard uses the redrafted Law Reference ISO 7322..2000 "Bonding cork test method" and GB/T 20671-2006 "Non-metallic
Gasket material classification system and test methods "prepared. The degree of consistency with ISO 7322 is not equivalent.
This standard proposed by the State Forestry Administration.
This standard by the Chinese Academy of Forestry Forest Chemical Industry Institute.
This standard was drafted. Xi'an Forest Chemical Factory, China Academy of Forestry Forest Chemical Industry Institute, the State Forestry Administration of Forest Products Quality Inspection
Inspection Center (Xi'an).
