Product standards are established guidelines that define the quality, safety, and performance requirements for various products. These standards ensure that products are reliable and meet consumer expectations. They can be set by organizations such as ISO (International Organization for Standardization) or ASTM (American Society for Testing and Materials) and often vary by industry. Adhering to product standards helps manufacturers maintain consistency and improve customer satisfaction. Additionally, compliance with these standards can facilitate international trade, as products that meet recognized standards are more likely to be accepted in global markets.
