D 774/D 774M, An American National Standard Standard Test Method for Bursting Strength of Paper
ASTM D 774/D 774M,
An American National Standard Standard Test Method for Bursting Strength of Paper
Bursting Strength of paper는 종이의 찢김을 시험하는 것이며 본 시험은
쉽고 저렴한 편입니다.
이 시험은 두께 0.6mm (0.025인치) 이내의 시편(종이)을 사용하여 30kPa 부터 1400kPa의 압력을 가하는 시험입니다.
1.1 This test method covers measurements of the bursting
strength of paper and paper products occurring as single or
laminated flat sheets not over 0.6 mm [0.025 in.] in thickness
having a bursting strength of 30 kPa up to 1400 kPa [4 psi up
to 200 psi].
1.2 This test method is not intended for use in testing
corrugated boxboard, liner board, or hardboards that tend to cut
the thin rubber diaphragm.
NOTE 1—Similar procedures for making bursting strength measurements
are found in ISO 2758 and TAPPI 403.
1.3 The values stated in either SI units or in other units shall
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system
must be used independently of the other, without combining
values in any way.
1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.

VCI Resin / VCI Film Test (ASTM D-1238, ASTM D-1505, ASTM E308, ASTM D4703)
VCI Resin / VCI Film Test
Volatile corrosion inhibitors (VCI) are a type of corrosion inhibitor used to protect ferrous materials against corrosion where it is impractical to apply surface treatments. They slowly release compounds within a sealed airspace that actively prevent surface corrosion. A typical application is to protect stored tools or parts inside bags, boxes or cupboards, one advantage of VCIs being that if the container is opened and reclosed, levels of inhibitor will recover.
VCI(기화성방청제)는
증기나 접촉 상태 모두에서 금속 표면 위의 부식을 막아주게 됩니다.
기화성 성분이 수면 위의 금속 표면으로 끌려와 산화작용에 반하는 분자막을 형성하여 가장 닿기 어려운 우묵한 부분까지도
보호를 해주는 물질입니다.
VCI 레진과 필름 테스트는 다음과 같습니다.
VCI Resin(per product):
Standard: Melt Index (ASTM D-1238)
Test Method: Density (ASTM D-1505)
Test Method: Color (ASTM E308)

VCI Film (per product):
Test Method: Anti-Corrosion (MIL-PRF-22019)
Test Method: Vapor Pressure (ASTM E96/E96M)
Test Method: Tear Resistance (ASTM D1922)
Test Method: Density: 0.92 (ASTM D792)
Test Method: MVTR: 9.0+/-0.5g/SQM (ASTM F1249 mod.)
