Machined from polished stainless steel and certified to ANSI\/ASTM E617 standards, this 500 g individual weight is engineered for precision balance calibration in analytical, pharmaceutical, and research-grade applications where accuracy requirements go beyond what general-purpose Class 3 or 4 weights provide.\u003c\/p\u003e\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eASTM Class 1 precision\u003c\/strong\u003e — among the tightest ASTM tolerances, suitable for high-accuracy precision balances\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePolished stainless steel\u003c\/strong\u003e body with a \u003cstrong\u003e7.96 g\/cm³ density\u003c\/strong\u003e, meeting the more stringent ASTM 0–1 alloy specification\u003c\/li\u003e\n \u003cli\u003eHoused in an \u003cstrong\u003eimpact-resistant plastic case\u003c\/strong\u003e with a recorded serial number for traceability\u003c\/li\u003e\n \u003cli\u003eMeets \u003cstrong\u003eANSI\/ASTM E617 Class 1\u003c\/strong\u003e specifications across the full stainless weight range\u003c\/li\u003e\n \u003cli\u003eAvailable as an individual weight for targeted calibration without purchasing a full set\u003c\/li\u003e\n \u003cli\u003ePolished surface finish reduces contamination risk, supporting longer calibration intervals\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003eDetailed Overview\u003c\/h3\u003e\n \u003cp\u003eASTM Class 1 occupies the second-highest accuracy tier in the ASTM hierarchy, just below Class 0. At 500 g, this weight is appropriate for calibrating precision balances across a broad capacity range, from analytical instruments through to high-capacity precision models. The 7.96 g\/cm³ stainless steel density specified for ASTM Classes 0 and 1 is more tightly controlled than the 7.9 g\/cm³ used in Classes 2–4, reflecting the elevated accuracy requirements at this level. This distinction in alloy density is an important aspect of achieving and maintaining Class 1 mass tolerances.\u003c\/p\u003e\n \u003cp\u003eThe polished surface and protective case help maintain the weight's calibrated mass over time. By purchasing individual weights, laboratories can select precisely the denominations required by their calibration procedures rather than acquiring an entire set — a practical benefit for facilities with specific, well-defined calibration protocols. The case also carries the serial number required for traceability documentation in quality management programmes such as ISO 17025.\u003c\/p\u003e\n \u003ch3\u003eApplications\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eCalibration of analytical and semi-micro balances in pharmaceutical and research laboratories\u003c\/li\u003e\n \u003cli\u003ePrecision balance verification for food, chemical, and environmental testing\u003c\/li\u003e\n \u003cli\u003eReference mass for accredited laboratory calibration programmes\u003c\/li\u003e\n \u003cli\u003eRegulatory compliance testing requiring ASTM Class 1 traceability\u003c\/li\u003e\n \u003cli\u003eReplacement or supplementary weight for existing Class 1 calibration sets\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3\u003eWhy Choose the Adam Equipment ASTM 1 – 500g?\u003c\/h3\u003e\n \u003cp\u003eFor applications that demand ASTM Class 1 accuracy at the 500 g denomination, Adam Equipment's individual stainless weight is a well-made, traceable choice. The inclusion of a protective case and documented serial number simplifies compliance with quality management systems. Adam Equipment's established presence in precision weighing ensures this weight is manufactured to the exacting standards that analytical laboratories and regulated industries depend on for consistent, defensible calibration results.\u003c\/p\u003e","brand":"Adam Equipment","offers":[{"title":"Default Title","offer_id":53765881364693,"sku":"ASTM 1 - 500g","price":165.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/9933\/4869\/files\/astm_1_-_500g.jpg?v=1778277828","url":"https:\/\/weighcore.com\/products\/adam-equipment-astm-1-500g-accessory","provider":"Weighcore","version":"1.0","type":"link"}
