ASTM E 21 包含了定義降伏強度,拉伸強度,伸長量與提升溫度之金屬減少面積的拉伸測試方法,在 ASTM E 8 中所描述的試片尺寸通常也適合 E 21 的測試。根據 E 21 ,試片必須是圓形,而此幾何形狀的材料尺寸 - 尤其是薄板或條狀樣式的材料,在 E 8 中,標距長度與直徑的比率必須為 4 ,應當確定力量盡可能軸向加載,為了促進此項測試, E 21 建議使用帶螺紋的圓形試片或適當幾何形狀的末端以符合此要求,當使用矩形試片或是有足夠的材料時,可允許夾持爐之外拉長的附柄兩端。 ASTM E 21 需要一台遵從 ASTM E 4 正確規格的測試儀器加上夾治具及利用電阻或輻射機制的加熱裝置,在試片周圍的空氣必須符合大氣壓力,當需要定義 降伏強度 時,必須使用根據 E 83 等級 B-2 的應變計。
 
為了保證正確的結果,我們的 萬能測試儀器 系列皆符合或勝過 ASTM E 21 正確的規格所需。當測試矩形試片溫度達到 350 ° C (660 ° F) 時,我們建議的解決方案包括一系列鋸齒夾面的高溫機械楔型夾置具,而對於圓形的試片,我們使用 V 型鋸齒夾面。以上所提的溫度,我們成功的使用符合試片末端的 拉力棒 加上試片有內螺紋的固定器,至於加熱裝置,當溫度範圍達到 600 ° C ( 1110 ° F) 時,我們通常是用我們的 3119 系列的環境箱 ,而當溫度高至 1200 ° C (2200 ° F) 時,我們建議的解決方案是使用 高溫爐 ,像是 model SF-16 三區的分裂爐。
 
我們提供金屬拉伸測試有效的應變計解決方案,我們的應變計符合或勝過 ASTM E 83 的正確分級,我們建議使用我們的 高溫軸向應變計 W-E440 系列來作環境箱溫度達到 540 ° C (1000 ° F) 的測試,此 W-418 或 W-E405 系列的應變計是 SF-16 高溫爐溫度達到 1200 ° C (2200 ° F) 的理想解決方案。
