MS 812:2021 is the Malaysian Standard that specifies the safety requirements, performance criteria, and test methods for fireworks. It is a crucial document for manufacturers, importers, distributors, and regulatory bodies (such as the Royal Malaysia Police) to ensure that fireworks sold in Malaysia are safe for public use.

By utilizing a standardized general tolerance like MS 812:2021, manufacturers ensure consistency across different production facilities and suppliers. It reduces the complexity of technical drawings, minimizes the risk of misinterpretation, and ensures that parts meet functional requirements while maintaining cost-effective manufacturing tolerances.

While specific values scale progressively based on the size of the workpiece, the standard breaks dimensions down into specific (measured in millimeters). Below is how the standard structures its inspection and validation criteria: 1. Linear Dimensions (Excluding Chamfers)

Follow this exact process to secure the optimal document:

Based on the standard code , this refers to a Malaysian Standard (MS) .
