第 2 版はキャンセルされ、初版と置き換わりました (ISO 6603-2:1989), which had been technically revised.

ISO 6603 consists of the following parts under the general heading Plastics – 硬質プラスチックの穿刺衝撃挙動の測定:

— 一部 1: 非器具衝撃試験

— 一部 2: Instrumental impact testing

The appendices A to E of this part of ISO 6603 are for reference only.

ISO 6603-2-2000 “プラスチック、硬質プラスチックの穿刺衝撃挙動の判定 – 一部 2: 計器衝撃試験”

1 範囲
ISO のこの部分 6603 specifies a test method for determining puncture impact properties of rigid plastics in the form of flat specimens using instruments that measure force and deflection. Applies if a force-deflection or force-time plot recorded at a nominal constant firing pin speed is necessary to characterize impact behavior in detail.

If ISO 6603-1 is sufficient to characterize the impact behavior of plastics by impact failure energy thresholds based on many samples, ISO 6603-1 May be used.

ISO のこの部分 6603 is not intended to explain the mechanisms that occur at each particular point in the force-deflection diagram. These explanations are the task of scientific research.

Note also article 1 of ISO 6603-1:2000.

3 用語と定義
For the purposes of this part of ISO 6603, 次の用語と定義が適用されます.

3.1 Impact velocity

The speed of the firing pin relative to the support at impact

注記 1: The impact velocity is expressed in meters per second (MS).

3.2 Force F

The force exerted by the firing pin on the specimen in the direction of impact

注記 1: Force is expressed in Newtons (N).

3.3 Deflection l

The relative displacement between the firing pin and the specimen support starts from the first contact between the firing pin and the specimen

注記 1: Deflection is expressed in millimeters (んん).

3.4 Energy

Energy used to deform and penetrate the specimen up to the deflection L

注記 1: Energy is expressed in joules (J).

注記 2 The energy is measured as the integral of the force-deflection curve from the point of impact to the deflection l.

ISO 6603-2-2000 “プラスチック、硬質プラスチックの穿刺衝撃挙動の判定 – 一部 2: 計器衝撃試験”

3.5 Maximum power FM

The most power that occurs during the test

注記 1: The maximum force is expressed in Newtons (N).

3.6 Deflection lm at maximum force

Deflection at maximum force FM

注記 1 Deflection at maximum force is expressed in millimeters (んん).

3.7 Energy to maximum strength

The energy expended at maximum force reaches deflection lM

注記 1: The most powerful energy is expressed in joules (J).

3.8 Puncture deflection lP

The force is reduced to half the deflection of the maximum force F M

See Figures 1-4 そして 3.9 notes.

注記 1 Puncture deflection is expressed in millimeters (んん).

3.9 Puncture energy

Energy expended until the puncture deflects lP

See Figures 1 through 4 and note 2.

注記 1: Puncture energy is expressed in joules (J).

注記 2 A probe mounted at a distance from the impact tip records the friction force acting between the cylindrical part of the firing pin and the piercing material when testing hard materials. The corresponding friction energy should not be included in the piercing energy, so the piercing energy is limited to that deflection, where the force drops to half of the maximum force FM.

3.10 Impact Failure

Mechanical properties of the material to be measured, which may be of one of the following types (ノートを参照してください) :

ある) YD yIELDING (zero slope at maximum power), then DEEP yielding
b) YS yIELDING (Zero slope at maximum power) それから (at least partially) cracked the S bench
c) yIELDING of Yu (zero slope at maximum power) Then u unstable cracking
d) no yielding for new features

注記 1: A comparison of Figures 2 そして 3 shows that puncture deflections l, P and puncture energy EP are the same for failure types YS and YU. As shown in Figure 4, in the case of failure type YU, the deflection and energy values are the same at maximum and puncture. For complex behaviour, 付録 A を参照.
