Rubber household gloves — General requirements and test methods

ISO 20057 specifies the general requirements and relevant test methods for gloves made of natural rubber latex or synthetic rubber latex or blends of natural rubber and synthetic rubber lattices intended for household use. ISO 20057 is intended to serve as a guide to obtain gloves of consistent performance. It does not cover safe and proper application of the gloves with subsequent handling, packaging and storage procedures.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

Rubber household gloves — General requirements and
test methods
1 Scope
This document specifies the general requirements and relevant test methods for gloves made of natural
rubber latex or synthetic rubber latex or blends of natural rubber and synthetic rubber lattices intended
for household use.
This document is intended to serve as a guide to obtain gloves of consistent performance. It does not
cover safe and proper application of the gloves with subsequent handling, packaging and storage
procedures.

glove back
part of the glove (3.2) which covers the back of the hand (3.1), i.e. from the wrist to the base of the fingers
4 Materials and manufacture
Gloves are generally categorized by materials, designs and surface finishes. Materials include natural
rubber latex, synthetic rubber latex and blends. The glove outer surface may be smooth or textured,
with or without pattern on the surface while the glove inner surface may be with or without flock
lining. In any case, the glove shall be either ambidextrous or in pairs (right hand, left hand), single or
multi-layers (laminated).
Any glove made of materials and manufactured with designs and finishes described above that meet
the requirements of this document is acceptable.
5 Sampling and selection of test pieces
5.1 Sampling
For reference purposes, unless otherwise stated, gloves shall be sampled and inspected in accordance
with ISO 2859-1. The inspection levels and acceptance quality limits (AQLs) shall conform to those
specified in Table 1.
Table 1 — Inspection levels and AQLs
