GB/T 2577 - Determination of Resin Content of Glass FRP

Standard System: GB (Chinese National Standard)
Current Edition: 2005
Product Category: Raw Materials - Resins
Test Category: Chemical Properties
Equivalent Standards: ASTM D2584

Description

GB/T 2577-2005, Determination of Resin Content of Glass Fiber Reinforced Plastics (Burn-off method). Removes resin matrix via high-temperature muffle furnace to determine resin mass fraction gravimetrically. Equivalent to ASTM D2584. Deviations exceeding ±3% from manufacturer’s declared value indicate process control failure.

How to Apply GB/T 2577 in Inspection

Applying GB/T 2577 starts with confirming the edition named in the contract, the product scope, and any purchaser-specific additions. Material system, dimensions, pressure or temperature rating, manufacturing route, and service environment should be mapped to the clauses that actually apply. Before testing, the inspection and test plan should define sampling frequency, specimen conditioning, calibrated equipment, witness points, acceptance criteria, and retest rules. A traceable report records sample and batch identity, the method and edition used, environmental conditions, raw observations, calculations, measurement uncertainty where relevant, deviations, and the decision against each requirement. This evidence chain supports purchasing acceptance, manufacturing release, engineering qualification, and dispute resolution. This page is an aid to discovery and interpretation; the current official publication remains the controlling source whenever its wording differs from this summary.

The sampling plan determines the population represented by the conclusion. Incoming inspection, first-article approval, type qualification, and production release carry different frequencies and risk levels; one selected specimen cannot stand in for a batch. Before shipment, confirm specimen count, dimensional tolerances, machining and end treatment, conditioning, and transport protection. During review, consider dispersion, failure mode, and raw curves as well as the reported average. Any anomaly should be investigated under a predefined retest rule so that an independent reviewer can reproduce the final decision.
