What is ISO 14644-2:2016 ?

Title: Understanding ISO 14644-2:2016 and ISO 14855-1:2016

Introduction:

ISO 14644-2:2016 and ISO 14855-1:2016 are two important international standards that cater to different aspects of the manufacturing process. ISO 14644-1:2016 is an international standard that specifies the classification of air cleanliness in controlled environments, while ISO 14855-1:2016 is a technical document that focuses on establishing a framework for testing the wear resistance of materials. In this article, we will delve into the purpose and significance of both standards, as well as their requirements and testing procedures.

Purpose of ISO 14644-1:2016:

ISO 14644-1:2016 is an international standard that provides guidelines for the design, construction, and operation of controlled environments, such as cleanrooms, to minimize airborne particles and other contaminants. This standard is highly important in various industries, including pharmaceuticals, medical devices, biotechnology, and electronics manufacturing. The main purpose of ISO 14644-1:2016 is to define the cleanliness level required for different classes of cleanrooms. The standard classifies the number of airborne particles per cubic meter (particles/m³) based on particle size and establishes the maximum allowable concentration limits for particulate contamination in each specified class.

ISO 14855-1:2016:

ISO 14855-1:2016 is a comprehensive technical document that sets the guidelines for determining the wear resistance of materials used in various industries. The purpose of this standard is to establish a framework for testing the wear resistance of materials under specified conditions. By defining the test methods, parameters, and evaluation criteria, ISO 14855-1:2016 enables manufacturers to assess their materials' performance and make informed decisions regarding their application in different environments.

Classification System:

ISO 14644-1:2016 and ISO 14855-1:2016 both rely on a classification system to categorize different classes of cleanrooms and materials based on their air quality requirements. In ISO 14644-1:2016, the classification system is based on the number of airborne particles per cubic meter. It also establishes the maximum allowable concentration limits for particulate contamination in each specified class.

ISO 14855-1:2016, on the other hand, uses a different classification system that is based on the American Society for Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (ASME BPVC). The classification system is categorized into ten levels, with each level representing a different level of wear resistance.

Testing Procedures:

Both ISO 14644-1:2016 and ISO 14855-1:2016 require manufacturers to conduct testing to ensure their products meet the required specifications. In ISO 14644-1:2016, manufacturers must conduct tests to determine the cleanliness level of their controlled environments. These tests involve measuring the number of airborne particles per cubic meter in different classes of cleanrooms.

ISO 14855-1:2016 manufacturers must conduct tests to evaluate the wear resistance of their materials. These tests involve subjecting the materials to various wear and tear conditions, such as friction, impact, and abrasion, to determine their resistance to wear.

Conclusion:

In conclusion, ISO 14644-2:2016 and ISO 14855-1:2016 are both important international standards that provide guidelines for various aspects of the manufacturing process. The purpose of ISO 14644-1:2016 is to define the cleanliness level required for different classes of cleanrooms, while ISO 14855-1:2016 is a technical document that focuses on establishing a framework for testing the wear resistance of materials. Both standards are essential for ensuring product durability and quality in various industries.
